- Update: New PWM video coming up • Thank you, Xiaomi! No ...
This is not the typical car photography videos that I share online but rather a topic that not many people talk about.
I decided to make this video because many people like me suffer from headaches and migraines because of pulse width modulation (PWM) & the new OLED displays. The only difference is I know what is causing it.
Storytime. A few years ago, I was diagnosed with a terrible migraine. It crept in progressively & I reached a point where I couldn't drive, dizzy and out of balance. I visited many doctors and was given many medications to control the pain!
Now if you are wondering what the symptoms were, it was:
Pain behind the eye and behind the nose, mainly to the right side of my face, felt like a sinus infection
Light sensitivity
Felt like I had a fever, without the fever
Dizzy & out of balance
Couldn't look at monitors and mobile screens
Being me, I never settled for this, I had to know what is causing the migraines to get my active life back. I have looked everywhere…. until I stumbled upon / karinnelson video where she was describing my symptoms!
I have also found this post on Reddit / massive_eyestrain_from... , and back in the days, I was using the Huawei Mate 20...
I know what you are thinking... It's only affecting a small percentage of people & it won't affect you. Well, you are wrong! I used the mate 20 for two years before my migraines started... which means you can build up that intolerance over time. I don't know if this means permanent damage but listen to this.
I recently bought the New Samsung galaxy s21 ULTRA... that was a mouthful. I fully charged the phone and was excited setting it up, I even played a few rounds of clash royal & then I went to bed... with a slight headache!
The following day I woke up with a TERRIBLE headache, more of a migraine that lasted few days... I quickly realised the New Samsung caused this and sold it the next day.
My go-to phone was the One Plus 8, which I bought a couple of years ago. It had a DC dimming option, and I was very happy because I found a good flagship device with that feature... But, ironically, they removed the DC dimming option with the latest update.
The following is a question to all smartphone brands out there ... WHY? If you could ease our pain with a simple optional software fix, why not include it?
New OLED Screen PWM Headache Video Update czcams.com/video/uVtylIuB_zQ/video.html
This answers everything. Back when I had an LCD display I never had any difficulties. Immediately after I switched to OLED, even looking at the screen has become a chore. Previously I used to read books on my phone but now I am unable to do it. I also miss the natural colors of good LCD IPS panels and I have noticed that sometimes the colors are too exaggerated and punchy on some OLED panels. OLED is still a developing technology and phone companies need to seriously consider making it better instead of adding more and more cameras to their phones each year lol. Technology should benefit everyone.
I agree, the "eye-safe" claims are false and OLED displays are not safe, at least not to everyone. I wonder how many are suffering without knowing it's their screens!
@@MoeZainal many people ! I had the samsung galaxy s7 edge before for almost a year and i had pain and so much eye issues and headaches , i didn’t realise its the screen until i got the iphone 13 few months ago and i returned it and brought back the iphone 11 thats i used to use previously
@@ismaelsteezy28 Most phone companies are fully switching to OLED now even for their base models. They really need to address these flicker issues.
@@MoeZainal I really hate all these dam Oleds and they affect alot more people than manafacturers and these youtubers are leading on. Even the nintendo switch Oled is so bad for the eyes.
OLED panels can have perfectly "natural" colours if the companies choose to have them appear that way. It's not the tech that is the problem but companies that may oversaturate the panel for their products. A properly calibrated panel will have accurate colours as the measurements show and if someone still says they are oversaturated then that is the person's incorrect feeling, not actual fact.
It's too bad these portable displays simply don't have smaller versions of oled tv displays. Oled TVs are great and don't have PWM flicker issues.
I got a galaxy s23 and my life suddenly got worse, eye strain, sometimes things looks blurry, a bit dizziness and headache, i though i was just getting old or something, but no, was this galaxy s23, is killing my eyes, sadly i discovered 2 months later, just by realizing that not looking at my phone was making me feel better.
Thank you for making this video ❤, sadly i really don't get it why others bigger youtubers or media don't talk about it, just because they don't have health problems doesn't mean is not happening to other people.
Btw honor 90 is a decent phone and have high pwm like almost 3000, maybe is my next phone.
I agree completely. The smartphone and computer manufacturers need to take note and eliminate PWM and other sources of flicker on their devices.
So I am PWM sensitive, and what I found helps is keeping your phone at 100 brightness, and then using a 3rd party app(Screen dimmer), that lowers the brightness by using a grey overlay filter to dim the screen. This has helped me immensely.
This is a good workaround, but I am sure it drains the battery if the brightness is always set at 100%. Nevertheless, it's a good solution.
@@MoeZainal surprisingly it doesn't as much as one would think. I don't know if this has something to do with the dimming app or not. I usually only charge my phone once to twice a day. Better than headaches..lol
I've been doing this exact thing for 4 years. I found I needed a 3rd party app like Night Screen after deciding that the darkest setting was still too bright. I recently received a probable functional neuro disorder (FND) + complex migraine dx, and am just learning about all manner of possible triggers. Some cause prolonged migraines. Others, when removed, seem to ease the migraines (FND).
So thrilled that you shared this info. You did a great job providing context and history, as well as detailing the nuances that make this an issue for some people. Looking forward to sharing this video with my doctors!
Regarding getting this info into the hands of manufacturers, based on my most recent role at Intel & other stuff:
1) Companies often rely on the number of customer support tickets and feedback posts to determine what goes into the IT backlog & road map.
That said, the more awareness & call to action (via feedback) spread amongst occupational health departments, employees at Samsung, LG, etc. and user forums, the more likely they will work toward fixes.
2) This may also an accessibility issue for visually impaired people. My husband is legally blind. He can't attend to a task on his phone at any level of brightness, and I'm starting to think this may be a part of the problem. Disabilities Rights organizations may be interested in this, as well and lobby for legislative changes regarding manufacturing of these screens.
@@nooreosleft thank you for sharing your experience and for sharing insights on how tech companies handle feedback, it's really helpful.
In terms of accessibility and disabilities rights, do you know which entity we could approach?
I was thinking of developing a website along with running a gofundme campaign to support our reach.
You seem to have a lot of information and ideas, do you mind sharing your email address? Could be the start of a PWM sensitive people committee.
How did you find out you had this? I was looking for a new laptop and someone said i shoudnt buy OLED it can cause PWM sensitive. But i used my Samsung s9 with OLED for 5 years now and dont think i have any problems? Is it really obvious if you have this?
Thank you so much! I am suffering from bloodred eyes, dry eyes, aching eyes, headache, etc ... It got to the point I could not work anymore. I replaced my iPhone 13 with the 2022 iPhone SE which works much better. Unfortunately, I had to replace my Macbook Air M1 with a Dell Latitude 3420 (and downloaded the Health Guard Software from Laptopmedia) and I stopped using Monitors since looking "downward" to a screen helps with dryness. Thanks to replacing my hardware, very frequent use of eyedrops (every 2-3 hours) and no more monitors (at least in private) I am feeling much better now. PWM and Temporal Dithering are a seriuos issue for me and I hope the manufacturers will address it soon. Thank you for spreading the message
Sorry to hear about your experience, I am so glad you are feeling better now ♥️ I hope they change this display tech because many are suffering.
Sadly LCD phones are going away. Gripping my iPhone XR very tightly.
No joke. These brands should be held accountable for their doodoo flicker boxes.
Thank you for bringing this topic up! I think all the devices with PWM at least must have some sort of warning or notification for people like us. I mean, you can't know for sure if it would work for you unlit you spend some time with that device. PC monitors have this option called "Flicker-Free", and that helped me to choose a monitor I can work for hours with no problem. This should be also present in features list of TVs, phones, tablets. Moreover, sometimes I get a feeling that people who don't experience PWM effects would think I'm crazy or something, because they don't even believe those screens can cause such health issues :)
I agree, it should be regulated
You answered my question which was in my mind for 1 year I thought there is something wrong with my eyes but now switching back to ips display everything is fine again and I can enjoy my phone without headache and blurry vision
sad to see there is no more good phones with ips!!
Thank you sharing such important information.
You are welcome! I am glad you have figured out the issue because it's really an awful experience.
UPDATE: Apparently, OLED displays PWM frequency or flickering frequency are low in comparison to LCDs. The lower the frequency the worse it get for PWM sensitive people. Samsung PWM frequency is below 250hz while the iPhone 13 frequency is above 480hz. They claim keeping it low provides better battery consumption and better colors.
Most LCD IPS panels use DC-Dimming that's why they don't flicker.
Update #2: I recently bought the Poco X4 GT with an LCD screen and it's heaven to my eyes. Although notebookcheck detected PWM, its frequency is so high at 50,000Hz, that's why it's safe for our eyes.
Sony LCD TVs use 720hz PWM at all times unless you enable the Black Frame Insertion feature called Clearness, then it flickers at 120hz. Samsung LCD TVs can do 960hz in Movie mode but uses 120hz in many other modes including when frame interpolation is enabled.
Huawei Mate50Pro and P60Pro PWM display is 1440Hz and that's fantastic for your eyes. The best result.
I wanted to Buy the s23 ultra but now I am not sure anymore because it only has 240Hz PWM. 😕
They've used PWM for LED-backlit LCD screens as well. It was just cheap and simple for manufacturers to sell that crap instead of spending a bit more for DC. It tooks years before they actually started releasing PWM-free displays. Now with OLED it's back to square one.
LG OLED's that are WOLED don't have PWM. I still don't know if I made the right decision with ordering an LG C2 42 inch model though.
this is correct, stick to WOLED @@flockelocke2297
@@flockelocke2297 Hi! How did it go?
Great video. For years I've been suffering and had no idea this was a thing until this year. I stumbled on a video here from a woman who suffered a lot. I tested it out with an old iPhone 8 Plus and my Note 9, iPhone 11 Pro Max and recently the iPhone 12 Pro Max I traded back to Apple. Picked up a new SE 2022 and have been headache, migraine free, no eye strain or tears. I was about to take medication for the migraines too. Unbelievable it was my phones all these years. I wish there was an offering for flagship phones with lcd or software option to turn on and off.
Thank you for sharing your story Jon, we all been in the same boat, I have actually took the migraines medications, it made me feel so bad that I had to dig deeper to find the origin of the problem. I am glad you have sorted it out. We need to get the message out there and hopefully they listen to us and give us a flagship with LCD. I just got Poco X4 GT and it has been a pleasant experience!
You probably still can find new Iphone 11 or some cheap Chinese phone
Dont you miss face id?
I recently got an OLED smartphone with a 2160Hz pwm. I no longer suffer from headaches, I love it
@@fs_1189 Hello, which brand and model?
Wow you have just described the symptoms I had, I thought it was a migraine but it’s not quite one, medication for that didn’t work, the doctor said a sinus infection, it was an out of body experience, I also couldn’t drive, didn’t feel stable.
I’ve avoided my phone and also now struggling to make choices with tech now
I'm glad you were able to point the main cause. Imagine all of the people that doesn't know why they are having migraines.
Same here! The driving is the scariest
Experienced this while turning your head? I had it like this, if I looked down or left/right I felt like I was about to collapse
THANK YOU FOR BRINGING THIS UP! I quickly learned I suffer from this after I had purchased my Galaxy S21. I unfortunately have to leave my phone at full brightness all the time just to not get migraines and eye soreness from it! The whole world is moving to OLED and I fear I'll have to deal with displays that cause me pain with no alternatives (notice how we can't buy CRT's anymore, LCD's just might wind up in the same place). I've just started a project that involves a small OLED display, and the *very* first thing I've done is get stuck trying to disable this silly silly PWM dimming on the display. Matter of fact, the flicker on this particular display is so bad that I can actually see the flickering to some degree. Again, thank you for making this video, as it's something I see only getting worse unless tech content creators actually start including it in their reviews and shaming companies who fail to implement such a simple accessibility feature.
Thank you for sharing your story, I feel your pain. LCD screens are good for PWM sensitive people like us. I am using Poco X4 GT which has an LCD screen and I don't get the headaches anymore.
would it be possible to produce aftermarket oled display, for these phones, without PWM?
Is there no solution to this? I wanted to buy the S. 23 Ultra but now I am not sure anymore! 😕
I am a LOT on my smartphone.
Have same issue , severe migraines using iphone 14 pro and did feel out of balance and all those symptoms , now back to 11 , i hope apple fixes this.. its a major problem
Thank you so much for bringing this up! It’s way to underreported. I had to sell my iPhone 11 Pro and get an 11. I can upgrade till something changes. I hope for a miniLED Apple phone. But probably won’t happen.
Thank you for sharing your story. It's very hard to get the media's attention. This kind of tech has to be regulated.
Hello Moe, great that you are talking about this, there are so many people out there who don't even know why they constantly have a headache. They have the problem in their own hands, a mobile phone with an Amoled display..I have the same problem, years ago you didn't know the problem, thanks to the Internet you can find everything. You should really start a petition against it. I also got my mother an LCD smartphone because she also had a very severe headache.
I am really glad you have found out what the problem was. I am thinking of creating a website and maybe launch a campaign to spread awareness about OLED and PWM but it won't be easy.
Me pasa lo mismo con el último móvil que compré con pantalla súper amoled, me provoca fatiga visual y escozor de ojos. Tengo un móvil barato con una buena pantalla lcd y los colores se ven mas relalistas y no me daña la vista. Antes pensaba que las amoled eran mejor pero ahora veo que es solo marketing.
I think that is an excellent idea, even if it was basic when first launching it would be great to get more awareness out there
Totally happening with me. I thought I was crazy. Thanks so much! Cell phone makers please create solutions!
They will never create solutions, they have intentionally manufactured a problem... So many people have NO idea the spiritual warfare they are up against. This world is about SO much more than money.
There are lot of issues with eye-strain and displays that don't get talked about enough in reviews etc. And it's not just OLED or pwm etc. I had 16 inch intel Macbook Pro that I gave me horrible migraines at default settings (i had blurred vision or the auras that are associated with migraines), but when I chaged the resolution scaling they disappeared. I have very good eyesight so that's not an issue of the text being too small etc, just some tech they use for the scaling etc. I'd like to get a MBP 14", but afraid it'll bring back the headaches (I'm using MBA M2, which is completely headache free). Unfortunately the reviews mostly focus on that the display "looks good". Thanks for this video.
That's a very interesting perspective, thank you for sharing
Don't get the MBP 14", worst screen I ever used in my life, mini-LED is even WORSE than OLED imo. By the way, you can make your MBA M2 screen look even better with the "Stillcolor app" that is able to reduce flicker even further and make the image more stable, search it up
Same feeling here... because of this, I have already bought 3 iPhone 11 so that if one broken, I can continue to use the second then the third. I don't know when the manufacturer will pay attention to this problem. The only thing I can do is to hoard more iPhone 11...🤣
These companies need to start correcting the flickering issue. It's causing some customers negative symptoms and even reducing their profits. I was planning on buying the recently released Alienware OLED monitor, but didn't due to the flickering issue present, Rtings review shows the substantial level of flicker. It's absurd that companies charge over $1000 for an OLED device, yet it has anti-consumer PWM flickering. Thanks for the video, this problem needs to be reduced before companies compromise more of our comfort as tech evolves further.
Shouldn't the Alienware be ''flicker free''? ''The backlight isn't technically flicker-free because it has a slight dip in brightness that corresponds to the 165Hz refresh rate. However, it isn't considered pulse-width modulation like on LED-backlit monitors because it isn't a full-screen on-and-off flicker, and you won't notice it.'' When I google then yeah you find posts about flickering issues. I ordered a LG C2 OLED and I hope my head can take this thing. I have problems with my Pixel 7 display but I think it's due to the bad pwm and the LG C2 doesn't have it.
Edit: The Alienware is rated 10 for flicker free, so I think it's nowhere near as bad as an Pixel 7 display for example.
@@flockelocke2297 True, they classify it as flicker free, but their graph still shows small changes in brightness. I assume that could cause some people sensitive to flicker, issues. However the Alienware does have more intense flicker when using VRR, as do all OLEDs currently. That was my main reason for not getting the Alienware or the new Lg 27" monitor. I'm so used to using VRR and Gsync in games. I remember how jarring frame dips used to be prior to this tech, so I wouldn't want to part with it. Hopefully they'll eventually get VRR to work consistently with OLEDs and remedy any flickering.
The Lg C2 looks great and the flicker according to Rtings is extremely minimal. You would still get stronger flicker if you're using VRR though. Users report VRR not causing flicker when your frame rate is very consistent, but any moderate fluctuation will cause flicker. As someone who mainly plays PC games, I prefer to use VRR. But you could always try locking your frame rate without VRR, things like that could be an option.
@@zsookah3 I only play on the PS5 but there I also became very sensitive. I remember playing 3 or 4 years ago, I had no issues at all and could take 30 fps easily and could play for hours. Now I even feel like watching TV or a stream on Netflix is a little ''slideshow'' ish. I don't know what it is?! I only switched from 27'' 75 Hz and 28'' 4K 60 Hz to 32'' 144 Hz and before that I had a PS4 Basic and Pro and now the PS5 with a M32U Gigabyte. Hmm okay, thanks for the Info. The PS5 has VRR at 60 hz too but then I will probably turn it off instead. An example is Elden Ring where I think it runs catastrophically on the PS5 even in 2023 and other people have no problems with it at all. Okay you're a PC gamer hmm I probably would wait too if it should be OLED or you could try an MSI 1440p with quantum dots maybe? What is your current display? Displayninja wrote that the 27'' OLED is the best gaming monitor on the market but yes you can only find out if it's okay for your eyes when you try it. But it's much money for trying and if the eyes or head make problems then you have the thing with returning.
Edit: I think the monitor market generally sucks a little bit because of overpriced monitors. For the price of the M32U you can get an 48'' OLED with better image quality and much better HDR and it's good for gaming too but it's just huge like very huge man.
@@flockelocke2297 Yeah, TVs seem to be a lot cheaper, compared to monitors. I use a 27" 4K IPS Lg monitor. It's been pretty great for a couple years now. It's bright and has accurate colors, but it has bad black levels. That was my main interest with OLED, to have better dark scenes. I'll probably wait till OLED is improved some, or might try out a VA or mini-LED. Although those seem to have their own drawbacks.
Ah nice, I assume you'd have a better experience using an OLED with a PS5. I think the frame rates must be much more consistent, with Vsync or VRR. So you'd probably not have much of any flicker. Many PC games run steadily, but quite a few fluctuate all over the place, I think nearly all of which would cause flicker.
@@zsookah3 I was searching for days in the net for a monitor when I got my PS5 in 2021. I also went for IPS and I tried the Rtings settings and it looks pretty good. What I find funny is when people complain about brightness or think, because they read, 400 or 450 nits or something that it isn't bright enough but then you look at the settings after calibration and there it says brightness is at 15 😄so it has 85 brighter steps. For HDR you need a little bit more maybe but you also need a FALD system or OLED. Yes, I would like some better detail and image in darker scenes and I hope that OLED can give me this. IPS is still much better than TN in that regard. VA has even better contrast but then you read things like black smearing and colors aren't on IPS level. Maybe there exceptions. It not so easy with these things but if you don't get a bad unit LG probaly is mostly a good choice. I have an LG Flatron M2262D from 2010 or something and this thing still works and I watch TV in the evening with it. 😜I feel like 27,28 inch is the best size for normal close sitting gaming. My 32 inch is too big for my taste and at a little bit distance it's too small somehow and the nice 4k is better at close range.
It is worth noting that not all PWM displays support DC dimming. Some displays only have PWM hardware so this cant be fixed in software as the necessary hardware is not included. another problem is flicker free OLEDs actually just used a modified PWM algorithm when you set it to DC mode. the display isn't switching to DC dimming its just increasing the speed of the PWM so its less noticeable. even DC OLEDS have a brightness drop as they draw each frame which can be perceived as flicker.
God bless you for this video....I was just just thinking OLED panels will solve the nauseating, migraine n loss of balance that average LED panels have been giving me over the years. Ryt now m using an old 2009 LCD monitor and a window 7 laptop with ccfl LCD display panels. N now with this video, I don't know what I m going to when the laptop eventually dies. Funnily enough, a lot of people think m crazy whenever i tell them that the LED PWM is making me sick n sensitive to light. This shows how small we really are. M in Nigeria, West Africa.
Nice Job sir
I came across this video by chance, but when I read the description of the video I said: wow. I've had your symptoms for many years, and I've never found an explanation. Mostly I put it down to stress. I started one Christmas with very strong migraines, vomiting, I had to stop playing videogames, everything hurt when I looked at screens, the lights bothered me, horrible. After that I started to look at the PWM of the devices, and I tried to avoid the ones that were bad for my eyesight, but as a precaution, not because I was sure of the problem. But after reading the description I connected the dots, made a timeline and it all started after 2 years of intensive use of a monitor with PWM, probably added to stress, etc. I still haven't fully recovered, I can't even play video games for 2 hours at a time, but I can work in front of the computer, study, and lead an almost normal life. I don't know if this is permanent or not, but what has relieved me 80-90% has been Botox. I have been using this treatment for 2 years and it has been a life changer.
If this helps anyone I'm glad, but when I read "which means you can build up that intolerance over time" I suddenly felt identified, and with the comment "I have been struggling the past 2 years and have now become really sensitive like you describe". I haven't tried OLED smartphones for a long time but a couple of weeks ago I was on one for 20 minutes and I started to feel a lot of pain. I am in the process of choosing a new phone, and I did some research about the PWM on each model, and the truth is that there is no top devices with LCD anymore and the HZ of the PWM is quite low in OLED models. I was interested in a Vivo X80 pro, but discarded, the S22 Ultra discarded, iPhone also, the only solution I have found is either a phone with LCD or phones like Honor or Huawei that have more worked this aspect. I know that each person is affected in a different way, the ideal is to test the devices, but this is very difficult to do in the shops so.
Thank you for sharing your experience. I am now using Poco X4 GT, it's a mid-range device with LCD, I am happy with it so far!
Is there no solution to this? I was happy to buy the s23 ultra in a week but now I am not sure anymore because of it! 🙁
This explains everything. I just got this sweet OLED monitor and was so excited but looking at it throws me off and makes me dizzy.
Sorry to hear so, the low pwm frequency in OLED displays is the reason why you are getting dizzy
@@MoeZainal Yeah, I ordered an LED, which is what my old monitor was. Never had any issues with that one.
Great video and very big problem for the sensitive people. I am one of them. Thanks that you made this video. Just one technical addition - PWM not just a software fix. It is also depends on hardware, on screen controller to be more precise. And it can slightly affects colors on screen. Probably this is one of the reasons why the manufacturers don’t want to mess with dc dimming.
Thank you for the addition. True that, but would they rather lose customers or keep it optional, so people who are PWM sensitive can enable it and use the device.
All TVs use it too (frequency usually changes related to your backlight setting) but it’s less noticeable there due to ambient light on in your room when watching TV counteracting it somewhat. The *only* TVs that don’t are Sony’s non-flagship LCDs (ones without full array local dimming).
Also, most off-brand LED lightbulbs use it. I’ve found Philips, Osram and IKEA bulbs don’t have it as long as the bulbs aren’t dimmable.
I have avoided OLED altogether because even with DC dimming and OLD Saver it might be doing harm to my eyes. Over the long run. It is so bad that my eyesight have deteriorate a lot. Luckily for me my sight is able to recover. Even my cooler vision is burnt out. It is a very scary thing to lose your vision.
So that means, lcd is less harmful for eyes? :)
@@RandomGuy-ws6td yes LCD display is cooler to my eyes
OLED also has burn in issues nobody wants to acknowledge and is bad for watching films (or other 24fps content) on as it shows up motion judder on planning shots which looks almost like strobing, something decent LCDs never had issues with.
I'll stick with a good LCD, never had any reason to dislike the good ones.
I use a LG c1 at about 1.2 M away its great
Awesome video. Same experience. Used an iPhone X for 3 years and then can not use any oled/miniled screen after that. If this affects a certain percentage of the population, why isn’t there a disclaimer on the box. This device has flashing lights and I’m pretty sure it could trigger epilepsy in susceptible individuals.
I’m the same. I’ve been using my iPhone X since 2019 and tried upgrading to 13 this year. I had serious migraines and had to sell it. I decided to try the 11 but it also has the OLED display and gave me headaches also so had to sell it too 😢.
So I’m still using my faithful old IPhone 10.
So people like us can’t enjoy modern technology, so unfair.
@@swiftlydoesit8480 the standard iPhone 11 has an lcd. Much better performance than the iPhone X and it can update to iOS 17. Look for that phone. Very easy on the eyes.
@@swiftlydoesit8480 The iPhone 11 has an LCD panel which is good, only the 11 Pro is OLED^^
The solution isn't that expensive to implement. All manufacturers have to do is make high frequency pwm flicker screens, like above 2000Hz. At that point human eye stops registering flicker and sees it as a regular source of light. Most of these amoled phones have 200-500Hz frequencies, even the flagship phones that have even lower than 200Hz which is terrible for all people, not just sensitive ones. Dc dimming kinda solves the problem but on some phones even that doesn't work. I still didn't use amoled display but every time I look at it it appears as offensive and unpleasant to look at so I might have the same problem. Thankfully there are still LCD screens in midrange segment but they started to disappear there as well.
I was happy to buy the s23 ultra in a week but now I am not sure about it anymore! Can't this be fixed on the S 23 ultra?
I am a LOT on the smartphone...
Do you know how much PWM the Huawei Mate 20 pro has?
Been having issues for 8 years. Everyone thought I was nuts. With each new phone it got slowly worse. 100% brightness and reducing whitepoint mitigates it a lot. Also- using it with natural lights vs. crappy overhead lights (that also).
Glad the message is getting out. I spoke with apple at length about it when I got my 12. They did not seem to care.
Yes, 100% brightness combined with a high Reduce whitepoint value (such as 95%) reduces the brightness of colors. It won't be overly bright just because of a 100 % brightness setting. The high Reduce white point setting mitigates that. I'm talking about my iPhone. On Android under Settings, Display one can change the screen mode to have less vivid colors.
Many consider IPS to be obsolete technology, but I still look towards the iPhone 11 and understand that this is the last iPhone with a comfortable matrix. Perhaps someone will add miniLed or microled to phones, they are not so aggressive, but we know that now global changes from year to year are not so frequent, and they mainly update cameras and design.
Well said. We still don't know how we will react to miniLED though
@@MoeZainalIPS is not obsolete as they have gotten better, less bezels and sharper than any high quality oleds displays. IPS is only obsolete for Amoled fanboys. Now in the actual smartphone market, budget phones have become the new mid rangers while keeping the ancestral shenanigans like ips displays, 3.5 mm audio jack and on top of it, the mighty micro sd card allowing the user for easy storage upgrade, needless to mention why phones with micro sd will still be better, especially if you rely on the storage for screen recording and downloading, in this case, micro sd helps a lot without wearing out the phone's nand.
It's not only because migraines, it's about destroying our eyes. The motor system of the eyes.
Very well explained symptoms, i too had same issues with Iphone XS Max, Iphone 12. Now using Samsung A series midrange and all symptoms are gone !!
Thank you. It's unfortunate that we don't get to enjoy flagship devices because of OLED and PWM. I personally now use the Poco X4 GT and it's the best in terms of specs + an LCD screen.
What samsung A are you using?
PWM sensitive here. I just recently changed my phone from 13 PM to Honor M4U (a gift from friend) and to my surprise, no more headache. Apparently this is due to its high flickering rate (around 2000Hz ish) that even PWM-sensitive eyes do not notice it. Maybe it can be a good alternative flagship phone to some (but it is Huawei though)
Absolutely, I got the Poco X4 GT and it has a flickering frequency at 50,000 which is crazy high, no headaches 👌🏼
How did you not feel the headache and the OLED screen? I suffer like you, and my device was the 13 Pro Max, but I sold it and got the regular 11. The symptoms are mild, but they are present and sometimes annoying. Should I look for a cheap device?😢
Worst thing is that oleds are nearly everywhere now, even in midle range phones! Producers do not give us another choice!
PWM gives me awful migraines. Thanks for bringing attention to this issue. I realize those of us who are sensitive to PWM may be a minority, but it's a massive problem for us. And PWM may have effects in the general population. I don't think anyone has studied the long term effects of PWM in the general population.
I wonder how many are we. Yes, a minority. But even if we are 5% companies should think about us too, they don't like to lose even a small percentage of customers
You do realise PWM is used in most LED lights, including cars, signs, etc. If you haven't noticed it there then you probably wont have noticed it on oleds either.
Bought new 2024 ipad M4 11, 3 days later I had to return, severe watery eyes and headaches.
Now got an ipad 6 mini, just fore bed time media consumption, oh boy, it is the best.
For me, my eyes really likes IPS LCD panels.
Same! Had to return after a week. Got severe eye fatigue within minutes, pain behind the eyes for hours afterwards. Not worth enduring.
it's because of low frequency pwm screen, HUAWEI and mi provide many high pwm products, I've already changed my apple to huawei, since then I never experienced headaches and eyes stress anymore
Honor phones are also oke, if you need google.
Why Huawei are you using?
This video deserves more views!
You are not alone. I also am PWM sensitive. I'm using iphoneSE and will stay with it just for this purpose. Yes, would like to utilize a flagship model, though cannot do so with headaches. Isn't there a jailbreak hack or mode we can install to override? Perhaps, there is an aftermarket screen that can be installed into the flagship models.
Excellent video, I just return the Xiaomi 11 T pro, Great phone, fast, well design etc but the monitor, 30 seconds and I start to see everything blur, I was looking for other option and everything I find was OLED until Moe recomendation, I just order the Poco X4 GT, Notebookcheck test Screen flickering / PWM detected 51540 Hz, looks veeery good for me. Thank you Moe!
I had a midrange AMOLED Samsung Galaxy for two years using it as a work phone from the company I work. I could never consider to have this model as my own, or any flagship so to speak only for its screen technology! Reading on (AM)OLED is good for short periods but not sustainable for longer. Color accuracy, sharp contrast and all that are absolutely true compared to an IPS LCD. Even if one does not see the flicker, yet it puts a heavy strain on the eyes even using it for viewing in "dimmed" light at night for example. Therefore my choice for a new budget phone (Xiaomi Note 10 5G) with all its downsides compared to its other (Xiaomi Note 10 Pro) counterpart was only the screen technology. I regularly read books on my phone and AMOLED is just not for me. So long I will buy any smartphone until LCD will be an option! Thank you for this great video!
Wise choice friend. I was planning to buy the new oppo a78 4g, when I found out that it came with an amoled display. I decided to buy the realme c55 which has an IPS punch hole display, 256 gb rom, micro sd card and supports the 33 watts superVooc ultra fast charging. Best purchase of this year
this pwm is not the only factor. actually ,even for a lcd display, which is with a led backlight as the light source,which uses pwm to adjust its brightness as well as the oled display does!
Same problem here. I've a Google pixel 4a. After problems I've installed a little free app called PWMFree and everything's ok.
Today I was feeling very bad. Very hard headache. I checked and my brightness was something like 70% instead 100%.. probably my son touched it... But it's a pain... And I don't know why producers don't even take care about a lot of people that notice all this issues... Thanks for your video!
I'm sorry to hear about your experience. I tried re using my one plus 8 pro few days ago, and started having sinus headaches. It's an awful experience and I hope smartphone manufacturers take this matter seriously.
True i have same problems with this new screens
Thanks for covering this as I too are unable to upgrade as I too suffer from this it’s sad that I can’t choose any of the latest phones
I am sorry to hear you're going through this. I am trying my best to share this video with the world, in hopes to reach a decision maker. One day hopefully!
Fingers crossed
Pwm is my big problem 😔😔😔. Last year I bought new Macbook pro couldn't use it even 10 minutes ahhhhhhh. After that I thought it is because LCD retina display and I sold it and bought new LG gram 22 laptop. Same scenario 😫😫😫. Sold it ))))))) Two weeks ago I bought new s22 ultra same same same. 😔😔😔😔 What should we do to use flagship phones and newest laptops. When I went to Apple genius bar and LG service centre. They said one thing laptop don't have any problem this is your eyes problem they said that they cannot solve it or refund. Big companies don't care about pwm sensitive costumers.
I am sorry you are going through this, it is an unpleasant experience and I hope brands would answer our demand for an eye-friendlier screens.
Goooddd newssss 😁😁😁. Now I'm sooooo happppyyyy. Because I can use my s22ultra without any issues. My method of use : First month I used with dimming mode with highest brightness and 60hz, lowest resolution. I had eye strain only after long usage. Second month I have changed my settings to turn off dimming, brightness higher than 50%, 120hz and highest resolution. Now I have no pain on my eyes even after using all day. I strongly believe my eyes adopted to pwm of s22ultra. And It is all about what you think. If you think about eye strain, your eyes will have eye strain. If you don't think about it use freely, eye strain will not bother you. Thank you. Sorry my grammatical mistakes ^^
Look on macrumors for the thread "Eye-strain while using iPhone X and up". Here you will see 5 years of posts since the launch of the iPhone X. There are many, many of us who still cannot use any OLED iphone (even the Mini-LED Macbook Pro and 12.9" ipad Pro) due to PWM (and possibly dithering issues as well.)
It's a nightmare as our world fills with lighting, car infotainment, TV'S etc, that use PWM. I used to love new technology but I'm stuck on an iPhone 7 plus with no solution other than mid/bottom range devices.
This is thanks to manafactuers like Samsung, LG, BOE for not caring enough to address the issue while their display technology is used in everything.
It's unfortunate that no one is monitoring these manufacturers for any harming tech! Like you said, displays are everywhere, from TVs to watches and OLED is bleeding into them.
I just received my Poco X4 GT ando love it, LCD screen looks great, almost the same of Oled but without hurting my eyes, it was the last 256GB on Amazon, the one before was Xiaomi 11T pro and this one works better, only missing feature is the IP against dust and water, but the camera it's even better, believe it or not.
The last TFT LCD from Xiaomi :(
I used S10 for almost two years before switching to an iPhone 14 Pro Max, which has more PWM frequency than the S10, at least according to papers (S10 has 240HZ whereas iPhone 14 Pro Max has 250HZ
Very interesting! Thank you for sharing.
Yes, I had problems with the fancy screen of MacbookPro 16" (2021 model). One thing that worked for me was when I reduced the amount of colors to RGB. The screen now looks less vivid, less stimulating. Interestingly I don't have problems with my AMOLED Samsung S8 with 250 Hz PWM (at least I think it is PWM). But that phone's colors are not that vivid compared to my iPhone 11 (which seems to give me problems, I will be using another phone for a few days in order to know for sure).
@@allkindsofthings1497 Yup, My brother was using galaxy S22 which has very low PWM frequency than iPhone (Typically 124hz PWM) yet he can able to see the phone for hours without any issues, He later swifted to IPhone and got the headaches and eye strains even after using it for seconds, this people can't afford the Apples colour calibration.
I just switch from galaxy s21 to the iphone 15 pro max and ive been having nasty headaches 😖
@@savagelouie4498 been there, it'll only get worse.
I upgraded my 2017 MacBook Pro to the a new 16" M3 MBP and I noticed the eye strain and other symptoms leading to a migraine. I have never had this issue before on other monitors and laptops.
I have until January to return the laptop, so I will keep this comment updated if things get better/worse.
Commenting so that I can see the update to your situation.
@@milenamiki1349 I also bought an Oled laptop for work. 4th day now of headache, and eye strain. Bought software to lower brightness without lower brightnes on the laptop and all kinds of eye health software installed. Still feels like a thousand needles hurts the eyes. Some people say that you get used to it, but I dont have issues with Oled on Iphone. I will try to return the laptop
There is more to it than just the frequency. I was fine with the iPhone 12 (226) but couldn’t keep the iPhone 13 Pro (480). I’ve read a few things about how PWM is implemented, like how stable the wave form is, can also impact eyes. I go between an s21u for photography and an iPhone SE for everyday things. When I first started to experience eye strain with the 13 Pro, it took me a few months before I could use any OLED screen again. Meanwhile, Chinese brands are currently a few years ahead when it comes to eye comfort. Luckily for people like us, Samsung is coming out with a new display (E6) that will have a PWM frequency of 1,440Hz. I am hopeful that by the end of 2023 most flagships will use these kind of screens. Fingers crossed that it helps!
That is very interesting! Will also look in to E6 displays. Thank you for sharing.
For last month I checked 3 phones with high PWM friquency(vivo x90pro+(with samsung E6), xiaomi 12t pro and realme 10pro+) and with every of them I had headake and eye strain. You buddy mentioned about problem with iPhone 13 pro, Im curious didnt u checked 14 pro also in this sense, because I would like to use it but scary of pwm effect
@@nerqal some people are effected by even +10000hz
Vivo X90 Pro+ got E6 and got same PWM: 222 hz
I'm fairly sure I've never had issues with phone screens until I got the iphone 12. It is crippling for me, I've never known anything like it. I had a oneplus 6 before and don't recall any problems with that display. My mum has the iphone x and while it's not quite as bad for me it's still not great.
Given what you know about differences in the way it's implemented, do you have any ideas why apple oleds seem to give me symptoms?
Received my Steam Deck earlier this week and was getting some eyestrain and nauseous feeling from using it for a not too long period on the first day. Thought it was something to do with the screen size and maybe my eyesight just getting worse but then did some searches and found out it uses PWM with its LCD display and that it is apparently at a lower frequency. Saw someone say to turn the brightness to max where it should go away and it apparently did for me since the issues when away so yeah, found out I am sensitive to PWM flicker earlier this week.
Good to know going forward yet sucks to be sensitive to it and now having to take this into account before I buy any portable device with a display including future laptops. I do wonder now if previous times I have ever got headaches with mobile and laptop displays after not too long staring at them if it was because of PWM or something else.
I have nausea under a minute looking at OLED. Shame I can't get good LCD phone and I literally have to chose 2020 model to stick to what I've got, which is eye soothing huawei p30 lite (my version is 2019). Always been pleasant to eye but since I discovered eye protection mode it's just like looking and the paper magazine. Great display.
👏👏👏👏👏👏👏👏👏👏👏 I can't praise this video enough!
Other than eye "ergonomics" with monitor displaying peak brightness at 100 CDM puts you into "legal" level color grading standard. From six months I've been working with 80 CDM luminance so it gives me the opportunity to have a better perceptual match between screen and prints observated under a high TLCI and CRI D65 illuminant.
Also against the Hunt Effect principle I have measured a better gamut with 80 CDM instead of standard 120 CDM for photography, with both my BenQ PD2700U and my LG CX 65 monitors: maybe is correlated with a better condition for the display technology electronics instead of pure color perception capabilities with higher luminance (which increases colourfulness).
Thank you for explaining the problem.
it sucks that companies like Samsung who push so much on this oled technology doesn't care about the health of their customers(I was taught in school that the customer is the capital of the company)Customers who buy the top of the line find themselves with emmicrenee and eye problems.Even Iphone Apple has the same problem on smartphones.
Doctors and ophthalmologists have smartphones to thank for their billings.
I was happy to buy the s23 ultra in a week but now I am not sure about it anymore! Can't this be fixed on the S 23 ultra?
I am a LOT on the smartphone...
I find wearing migraine glasses or activating a rose tint on oled screens work pretty well but it definitely isn't a complete solution. But it's not just oled, some led lights use a very low frequency pwm flicker so I need to use migraine glasses for those too
May I know what glasses u have used ?
WoW. Didn't think about this. Explain some of my issues. Thanks
I've also noticed this has become an increasing issue for myself as well. Had a OP7P for 3 years and with the latest TVs I still feel off after using them. Ended up selling all of them without realising it was the TV's that were the cause. Good to know. I guess it's best to stay clear of OLED laptops, TVs, phones etc until it is fixed.
True that but some of the comments suggest that some of the TVs have fixed OLED by increasing its flickering frequency.... I have not verified this but I wish they would allow us to switch between DC Dimming and PWM.
OLED TVs do not have pwm dimming. I feel great watching them no eye strain.
LG OLED C2 is rated 10 for flicker free and it doesn't have pwm. On Reddit someone posted a comment about having problems with an OLED phone screen but not with his TV.
Hey I just heard that 10% population in the world suffering from the same problem.. I don't know why companies not recognizing it..
Im getting rid of my oled zenbook for the same reasons... horrible headache
I am having these symptoms too. They acted like I was crazy at the Apple Store. I am a UX/UI Designer. I have to have a computer to work. I can only use my old laptop.
Which laptop ?
It is not only PWM. I find that I get problems with screens (both phone and computer) when the colors are too vivid and exaggerated. I just found this today and am testing it: From Android Settings, tap Display, and then tap Screen mode. Tap Natural (or Basic). Don't choose Vivid. Also under Settings, Accessibility, Display there may be some setting affecting color. My Android phone is old so can't check it now.
Galaxy tablets look bright green to me all the time. Something definitely wrong with oled.
I'm also PWM sensitive, iPhone SE is the way to go :)
Is better with Iphone SE ??
Technicality here, but Pulse Width Modulation actually turns the lights on and off at a constant frequency, but stays dark for a longer portion of that time. Some LED TVs do switch to a faster PWM frequency below a certain brightness threshold though.
Loved my Samsung Frame but just couldn’t bear the strobing, even at the 960 Hz modes. The art mode looks like 120 Hz so it’s more like a distracting disco strobe light in my eyes.
Pro Tip for TV: Sony X85J. The X90J has local dimming using PWM (albeit a sine wave shaped PWM instead of hard on and off).
Wow, that's too technical and very interesting as well. I'm struggling with smartphone displays, flagship displays... I hope they recognise us and fix it.
Any high speed camera demonstrations of PWM? I've not seem them and I don't seem to be able to experience it on any OLEDs. This should be a demo to show us how PWM is working - like the flickering of CRTs or CFLs using high speed cameras.
@@jamesm5192 It's literally just the backlight flashing on and off. There's a lot of different forms, I much prefer a smooth sinus wave like pattern than a hard square wave. Some Sony TVs do it well where they don't refresh the whole display at once but do it in zones so the overall brightness stays constant, sort of like CRTs where it lights up the even and then odd lines.
@@Hamachingo Ya I was just confused because I assumed OLEDs had "off pixels" (for perfect blacks) and "on pixels" for the rest... Turns out for the majority of OLEDs the areas that are on are turning on and off really fast, which totally makes me reconsider it as a superior technology. I guess there are DC OLEDs, but I never see them advertised. I miss my high end CRTs for sure! Fingers crossed on some of the new OLED displays being DE, but I like my screen quite dim half of the time I'm using it so maybe OLED isn't the right tech for me. But which tech has great blacks and the most constant signal possible?
@@jamesm5192 I mean CRTs have the "pixels" turned off most of the time and they only light up briefly between 50 and 120 times per second. The electron beam is alway on though so at any point in time there's always "on" pixels somewhere and it's not strobing the whole screen.
I hate looking at my OLED iPhone in the dark. 240 Hz PWM is awful. Samsung Frame TV: 960 Hz (and that only in some modes... and it dropped frames here and there), still terrible, had to return it. Ended up with a Sony X89J (the X85 is identical except for the stand, the 89 is often cheaper). They got the PWM-free dimming figured out, I guess it's because Sony is popular among Gamers and those are way more likely to notice flickering, dropped frames, etc.
Noticed this with the steam deck, just thought I was getting old
Same issue here with my s23 ultra...
Here is an idea for phone makers out there!
1. Create an IPS phone, high/middle end (fast, latest android version, good camera etc)
2. Pay youtubers to review and make sure they mention that eye issue does not occur on this phone and image quality is ok in comparison to oled
3. Advertise it as much as possible on internet, etc
4. This problem will become more obvious as more and more people are aware.
They could get 10% of the market if the phone(s) they make are good !
For how long you have to use the S 23 ultra so that you get problems?
I was happy to buy the s23 ultra in a week but now I am not sure anymore because it only has 240Hz PWM and I am worried that I will get problems with it.
I am a LOT on the phone by the way. And I am worried because of my eyes.
Do you have any suggestions what I should do?
Sorry about late response. Borh my wife and i had problems with s23u within 15 minutes of use. It was obvious something weong with the phone. I returned it after 25 days, after viewing so much info about pwm in youtube (i wish i knew about it earlier)
@@FSWEB2011Same here, and now I cannot get rid of it.
I have the same issue with all new devices. I returned a TCL 65'' TV, a Asus Game Laptop, a Samsung A54 and now a S23 Plus. I'm considering suing those companies to bring attention to this matter. I work with my laptop and phone all day and spend my evenings watching series and movies on my TV. I never had any Eyestrain or anything related. However I always had a sensitivity to flashing lights for emergency vehicles, other than that, this is all new to me. Somebody please enlighten us on this matter and what can we do. Thank you
Thank you for the video.. many people feel the same way.. I'm still stuck on the iPhone 11
We bought a new oled tv last year and I've started to notice that I have eye strain after looking at it. Its weird I usually get more of it if Im gaming but if im watching videos ect my blood vessels on my eyes just get supper big and the eye becomes supper itchy. If I stop looking at the screen it helps. I have computer monitor thats va panel and I have no issues with it. I think its pwm but im not sure. I've noticed if i turn hdr off then that helps a bit. I didn't have this problem at the begining but It all started when I got an eye infection from covid and ever since then I've had problems with oled screens. Its so anyoing!!!
QD-OLED Alienware is in the box right now because it ruined 8 months of my life with headaches. I have CRT's Plasmas and LCD's and I've never had these issues.
I guess everyone with the headache problem will need to wait until they can get OLED screens with refresh rates in the 240hz range where the PWM speed will be way too quick for the rods and cones in your eye to respond to. (120hz screens are on a borderline where the really dim shades can still have an effect. Definitely with the 60Hz OLEDs, some can even make out a type of continuous screen grain/modulation on the lowest brightness shades.) As for the PWM, it can consumes less power compared to DC dimming and generates more accurate colors at darker shades. IE: battery life and accurate colors are what everyone is asking for...
240 hz will use a lot of power, they won't do that.
The S 23 ultra has 240 Hz PWM...
Everyone says that this is really LOW and also causes headaches, bad eyes, nausea and so on. Why then you say that this is ok?
I was happy to buy the s23 ultra in a week but now I am not sure about it anymore because it has just 240Hz PWM...? 🤔
@@alparslanmetehan9678the S 23 ultra has 240 Hz PWM and all people are saying that this is a very LOW number! The I phone has 480Hz PWM and others way above that! 🤔
Thanks
Very excellent and interesting documentary - learnt new things today and if I spend too much screen time in front of mobile then do get Migranes.
I think it's the other way around. It's when you lower the brightness that flickering increases. Because they turn off/on the backlight more times to create the effect of lower brightness.
The darker it gets the LESS often PWM goes on and of. Lower numbers are more harmful for the eyes.
So 1400 Hz PWM= good
240 Hz PWM = bad.
Oled displays have another massive disadvantage: they are far too rich in contrast. Normally, high contrast is not a disadvantage, but the content displayed is usually not optimized for this. Dark image areas literally drown and bright image areas such as text, icons or websites burn your retina away. I was really shocked when I compared oh so great flagships with my ancient iPhone 6s. Smartphones are mobile devices that are rarely viewed under ideal conditions, so black levels that are too low are more of a disadvantage than a benefit. The coupling of the brightness of the Oled displays to the brightness sensor is also patronizing. I once set a colleague's relatively recent iPhone to full brightness indoors and placed it next to my 6s. Now guess which display was significantly brighter…
All Huawei phones and tablets support DC dimming. All Huawei monitors are TUV Rheinland certified flicker free.
Thabks, the mate 20 didn't have it - Huawei smartphones are really good, but now without Google services its kind of boring.
I just got an OLED Steam Deck today and I am getting headaches and feeling dizzy after short session playing it. What a bummer - I do not know if I can return it to my local store.
I’ve just got an iPhone 14 pro this week and my eyes instantly hurt when looking at it. I have come from an iPhone 11 Pro and have been fine with it for 3 years which is confusing as it’s still OLED apparently 🤷♂️
I went to the opticians and they said there nothing wrong with my eyes but also said it won’t be the phone screen!! This post has helped but is also worrying that many people may be suffering from this without even knowing, and professionals like opticians haven’t got a clue either!
This is the explanation I've always heard but I still feel this even with OLED devices that supposedly do not use PWM dimming.
Damn, you must be very sensitive to it. I have an OLED monitor and I use it for about 10 hours every day. Every single day, so that's 70 hours a week, but not a single headache. It's a shame it totally affects some people, but not in the slightest on other people.
Your monitor might be using DC Dimming. And even with PWM Dimming, monitors use higher frequencies so it's easier on the eyes... But yeah it affects 5 to 8 percent smartphone users.
I am suffering terrible headaches with a lot of screens, unfortunately not a lot of persons talk about it
i can't use any phone , if a just see the screen of any phone i have headache , take painkiller
Try getting an LCD IPS display phone, or one that supports DC Dimming.
but i Phone se does't give me headache because of its LCD retina display, and i am using hp pavilion LED display without any headache problem, but any android phone like samsung , mi , oppo , vivo, realme , poco gives me headache even just seeing for 2 second. i have been suffering from last 3 years when i bought mi 6 in january 2018 and its screen was flikering but i ignored, i have consulted two eye specialst one of them prescribed me +0.25 cylendrical blue light cut glasses, eye drop and other one prescribed me +0.25 spherical glasses ( i am using it now a days during screen time). i have consulted a Ayurvedic doctor it said that its your posture problem ( he didn't get it ) . i have tried homeopathic medicine for eyes muscles recovery for 4 months but nothing work during this period i was taking pain killer (naxdom 250) . Then i took teatment for migrain for 4 months it prescribed two over the counter medicine and one for migrain attack ( maxprox 250 ) , As long as I took the medicine, it was fine after that the headache started again. so now a days i am taking one medicine for eye muscles recovery , eye drop and pain killer and i will start the migrain medicine again ........THANK YOU FOR READING THE COMMENT , i am from India
Samsung seems to know and doesn't care. Their flagship hurt my eyes badly to the point I need to sell it.
I used to have some cheap LED worklights that gave me a headache. I had to return them because they flickered so much.
I haven’t experienced any migraines from using a phone, but I did just get my first OLED smart phones. I guess I’ll see.
Thanks for sharing this information!
You are welcome!
I've always had my device brightness turned down and red filter to help with eye strain. I do have light sensitivity but I've never experienced anything like this before with my devices. I got an S23 recently and used it for a few days before I started feeling like I had been staring at the sun - burning eyes, dark spots on my vision, headaches, nauseous and my eyes feel like they are having seizures. I hope these symptoms go away and don't exacerbate the sensitivity that I already had. Looking for a new phone with LCD but none of them are the flagship specs that I really want. The S23 is everything I wanted but unfortunately it is making me feel so sick. This was my first amoled. I'm returning it.
i think we are on the same boat, was using huawei p30 (also 240hz pwm) but i am totally fine with it, but just changing to s23 yesterday, and start to feel nausea tonight, sad case indeed
Did you changed the phone? I was happy to buy the s23 ultra but now I am not sure anymore about it because it only has 240Hz PWM. I don't want to hurt my eyes even more.
So you would not buy it?
I think I may have the same problem, after i using iPhone with oled screen and I start to get headaches and don’t realize it maybe the reason.
Try another phone with a high PWM frequency or a phone with a DC Dimming feature.
All I know is I bought a 75-inch LG OLED after wanting one for many, many years and had to return it two weeks later. I experienced nausea, dizziness and horrific headaches within minutes of watching a show on it. I was so disappointed.
I noticed the pmw modulation, it can be distracting to me , but I don’t let it annoy me bc anything at all that annoys me gives me a headache
Modern Chinese phones have 2160 hz pwn and higher.
I bought one, tried, and it worked. 2 hours of getting used to it, and now it's like magic.
Samsung doubled the PWM on the S24. Some people are claiming it fixed the problem while others say it did not. I'm beginning to think the migraines for some are not caused by the PWM.
Flickering is bad as on the s23u. 480 hz during all brightness levels. It's the phone. Samsung does not deserve to be defended in this
@@smitjee Thanks for the response. What is it then? Is it the LTPO panel?
@@hermanwooster8944 Their way of using pwm. Look at motorola, xiaomi, oneplus, honor, they at least have settings to lessen the effects.
I am really sorry. Right now OLED is the best panels with it's infinite contrast.
If the DC feature is easy to add, then they definitly add that feature.
But don't be upset that much, Mini-LED technology is also a good alternative. Who knows maybe that will be used widely.
I have the same problem i bought 11 pro after using 8 plus for 4 years it was the most comfortable screen for my eyes ( i mean the 8 plus ) but the 11 pro immediately made my life hell , headaches, dizziness , nausea , i did not know the reason until a week later . .

Nothing is improving: preordered the 15 Pro Max in continuing hope that something has changed. After one evening of use I have eye strain, brain fog and tension + I feel nauseous. I’m now on day two of not using it and still feel the same. The worst affect was waking the next day, opening my curtains and having the sun hit my eyes - my vision started to strobe and hurt a lot, it was actually very scary. I immediately boxed up the phone and returned it. I feel like I’ve damaged my vision and pray I feel better in the coming days.
This is the 6th year of trying to buy a flagship OLED iPhone only to have to return it because it makes me feel ill. Total bullshit situation which Samsung and Apple clearly don’t care about.
Got Samsungs flagship tablet S9 and it also flickers. Some years ago got Lenovo X1 carbon, also their flagship and with hdr display. Wasn't actually real hdr display and I can use it only with external monitor. I will avoid new oled screens until they fix these
I also had the same issue with my eyes. even my eye sight is now weak and it caused some time pain. so I tried redmi 8. that is good phone for the eyes.
