Hey everyone! Thanks for all the great comments. I appreciate the feedback, both positive and constructive. Keep it coming! Now, what's the one thing you MUST know about the performance of the Sony A95K QD-OLED TV. Anything but price. That info just will not be issued for another couple of months. Let me know as a reply to this post!
My 2 biggest questions: Is there any form of ABL? How bright will these panels be in a calibrated state, no fluff, just real world performance? Thank you Caleb!
I watch a lot of anime and Korean content that need subtitles. With the upped resistance to burn in, do you think the QD OLED is an OLED that's fine to watch 8+ hours of subtitle content a week? (lets say 500 hours a year).
How do 4k Blu rays look on it? How does Dolby Vision and IMAX enhanced Disney+ content look on the new QD OLED from Sony Master Series?
Would like to know Real world brightness not in vivid mode.
Thanks Caleb! Having been pretty familiar with the inner workings & tech behind QD-OLED, this is a great explainer video. I also think having just a single Blue based OLED layer, there is less chance of uneven aging and the display may not show a Red or Green color shift/tint.
yes , all well and good , but still waiting for Pioneer to reapper and shock everyone with a 4K Plasma display !
The 1080p kuro still king of TV's!! You can mimick this by adding 20% window tint to any cheap plasma.
I still have a Pany plasma tv from 2005. Still runs great…and still throws out a lot of heat.
@@RARufus, me too, 2006
Great video mate, thank you. Can't wait for you to review in detail this QD OLED
Was waiting for this video since I checked articles on qd- display.Great work
Well explained. Haven't been so hyped for a new technology in years.
that was very informative Caleb, thanks as always for another great video !
Glad you enjoyed it!
Thanks, Rich!

As far as I know, there are three stacks of blue OLEDs on QD OLEDs. At least that's what was mentioned on a patent.
This makes a lot of sense! Great explanation 🙌
Glad it was helpful!
Outstanding video, very direct and informative. Thanks!
Glad it was helpful!
pumped to see your finding this years
Just one thing: quantum dots still sap some of the energy from the light for color conversion. about 20%. the thing is that is still less than filters, so it's better.
I'm pretty familiar with the tech behind QD-OLED, but I've been anxiously awaiting this video with your breakdown, Caleb. Thanks so much!
Thank YOU!
I still run a 2008 Pioneer Kuro. A true RGB display, the Jacob + Katie Schwarz 4k vids look stunning even at 1080p. QD OLED is the next gen Kuro I have been waiting for.
You lucky so and so. Finest flat screens ever made IMO. I'm hoping a 65" true microLED beast might take that baton.
Kuro is King!! It's a secret dark glass and dark phosphur. The Panasonic zt65 beats it slightly. Also if you get cheap old plasmas. Simply window tint them 20% and it's stunning!!
@@tonymemory2279 wut
I have a 50 pioneer elite, still blows away all of friends tv’s
My Panasonic VT60 plasma is still going strong. Looks better then most 4k TVs except for OLED. I just purchased the LG C1 oled for my game room. It will be my 4k hdr movie and gaming tv while my VT60 will be for sdr 1080p movies. 😊
Love your work keep it up thanks
A TV that runs many hours a day may not be “watched” full time. A TV could include a device that recognizes when there are no eyes on the screen and dim the intensity of the blue led. Commercial breaks could be toned down to give a “break” to the led. It sounds like some sophisticated processing is being used to monitor the degradation of the quantum dots, so a simple tracking of TV watching could be implemented easily.
Yes, we need more big corporations perving into our living rooms with cameras that are permanently on. This is the only way to completely preserve the quality of the blue OLED light in our televisions.
Thanks for making this video that literally exclusively restated my exact posts in your original CES QD OLED video. I'm not being sarcastic here. This video will reach way more people than 5-6 individual posts.
If we have to expect an extremely expensive Sony a95k line, I can’t wait to know how extreme it will be. They look like terrific tvs and technology.
Thanks, Caleb!
You are great explaining 😍
Thank you! 😃
Awesome presentation!
Great explanation 😊 good job!
Glad it was helpful!
This channel has become my go-to channel for TV related tech.
I always thought OLED used an individual oled "unit" for each oled pixel. Whether it's LCD, oled filters or QD, we are just using advanced prisms to get colors. I would really like to see us use just one layer of self emitting pixels; micro led or micro oled.
Thats exactly how it is in phone oleds.
Great explainer vid Caleb, thanks! What's the name of the other tech you mentioned at the end of the video? It sounded like QDEL - emissive quantum dots but with no organic materials at all. Thanks.
Yes it was Qdel or quantum dot Electro luminescent whereby electricity is used instead of light as a more efficient direct self emissive display.
Where can I purchase the LED sticks in the background?
So, how are quantum dots better than color filters? If they turn blue light into red and green, don't they lower the brightness also?
Im looking forward to the reviews.
I'm interested to find out more about microled. Have a great weekend Caleb.
Great video.
that was definitive and excellent .
Great presentation. Thank you from Canada 🇨🇦
Thanks for watching!
I'm eagerly looking forward to Sony's introduction of the A95K QD-OLED TV and Caleb Denison's full review. Even though I'm rarely an early adopter I could seriously consider opting for this new TV technology. My plasma TV is starting to show its age and Sony's A95K flagship model would be a premium upgrade.
hi,how old are your plasma tv?
@@holprod00 The plasma TV I have is from 2014. It was the last 1080p plasma model that Samsung made. It is still displaying a bright, high-quality image, but I recently had to have the power supply board replaced, and shortly after that repair, a couple of vertical lines have appeared on the screen that are one pixel wide. These could just be caused by some faulty connections that might easily be remedied, but so far I haven't gone to the trouble of removing the back of the TV in an attempt to fix the problem.
Don’t stop using that plasma use it until u can’t get it to work at all anymore. That is as new as the plasmas get and one gorgeous picture. These new TV’s are amazing but soo was the plasma even just 1080p. Hope u can make it last many more years
@@garrettstrutz7421 Thanks - The plasma TV is still working well. I'm still impressed with the lifelike image it is able to display. Yes, I admit that it can't achieve infinite black and HDR highlights, but I continue to enjoy its picture quality. And as for being limited to 1080p, I'll just say that unless you are watching actual 4K source material, the picture you see on your 4K TV is just simulated UHD. I will upgrade my TV eventually, but I don't like the idea of needlessly turning good electronics into landfill waste.
Such good detail!
Thank you! Cheers!
Great review Caleb. I purchased an LG CX 55” based on your recommendation, and love it. What worries me is that Samsung ignore Dolby Vision which I love and this is a big sticking point with their products. Still, if they were to bite the bullet and use DV, then I’d buy this product without hesitation.
I don't think they really need Dolby Vision while they have HDR10 technology
@@abdullahalqattan3861 but do Disney, for instance, support it?
@v cam HDR10, yes, but most mid-range or higher displays now are pushing HDR10+, which is actually superior to DV because it was finalized after, and has been around since 2017. It can not only do the scene-based luminance like DV, but also do higher peak brightness. The DV spec peak brightness is 1000 nits, where has HDR10+ peak brightness is 10,000 nits. There's no consumer displays on the market that can hit over 1000 nits quite yet, but they're coming, and HDR10+ is future-proofed quite a bit better. The other upside is that HDR10+ doesn't require the special decoding hardware that DV requires, which means not only is it better, but it doesn't cost money to license and install in TVs, meaning that displays don't need to charge extra for it.
@v cam @neomic Answer: HDR10 and Dolby Vision are two main HDR formats. The difference is that HDR10 is an open-standard and non-proprietary, whereas Dolby Vision requires a license and fee from Dolby. ... However, Dolby Vision does offer a better picture quality, mainly due to its dynamic metadata
@@IAmNeomic you are so wrong I actually feel sorry for you. Dolby Vision spec is optimized for Rec 2020 coverage which is 12bit color and also for a peak brightness of 10,000 nits.
Great explanation 👍
Glad it was helpful!
Hi Caleb, very interesting video. I am very afraid of the prices of qd-oled televisions in Europe. The Sony A90J currently costs around EUR 2,500. But I hope that TVs (monitors) with this new technology will become cheaper the more manufacturers will use this new technology. Hope dies last. :)
Should I wait or buy the LG c1 choices choices.
Great Video!!!
Thanks!
Where did you get your Lamps in your back ground if you don't mind me asking.
I'm very excited for QD-Oled...as soon as I can get a larger size at a decent price I'm in
I'm excited to buy this in a few years lol. Very informative!
You and me both! Thanks!
I'm excited to steal it this year. I'm already planning the heist with 10-12 other people.
@@TheJjjoj Hit me up. I'll drive the get-away van.
Caleb! Have you done a review of one of those old school CRT overhead projectors? If not, you should!
Hello. Something slightly different. Is the SonyX95K a master series please. Many thanks.
Nice content
Excellent video as always!
Can't wait for my coming Samsung Galaxy S23 that using this Quantum Dot OLED 😍
It's delicious 😋
so yeah there is no burn in per say but if one layers is used more they just wind up dimming the others down then right ?
Quantum Dot has been around for quite some time. Were the bt2020 color volumes not reachable with QLED TVs?
BTW- Thanks and keep up the great work!
Brother what do you do with all the products you get?
I stuck with LED and picked up the 85Z9J. (As per your recommendation) Awesome set, clean screen, insane HDR and more. Kinda disappointed that the Z9K is coming, but from what I have seen with the current crop of Mini LEDs, I just don’t see the benefit. Currently, trading a gain in contrast for brightness, blooming and screen uniformity.
Let’s hope Sony can get it right!
Thanks Caleb!!!
I wonder how pricing is going to be for the first few generations. I’m expecting incredibly high for early adopters
The 65" QD OLED will be about $8000.
Edit: Vincent says $4000 now.
@@GordonJones88 vs 83" OlED with heatsink $5000- other option buy a holding TV $2000 - buy 83" QD-OLED in 4 years for $6000- note not so silly as Media using full BT 2020 needs to catch and /or be broadcasted
@@nimblegoat I believe your cat might be walking across your keyboard.
They are not early adopters if they have been supporting the company by buying their products for years. Samsung oled in phones (even in laptops), and QD LED in TVs.
They brought these technologies together and it seems the only thing the innovated beyond that was how to monitor each pixel to ensure longevity.
So that $6000 (assumed $8000 price tag total for QD OLED for 65 inch) premium over other OLED costs (WRGB OLEDS are going to be much cheaper for around $2000) seems to be mostly for their longevity, considering they have been making QD and OLEDs for a long time (their old tech), they have the cost down for that. So their new tech so to speak is just for longevity monitoring.
Im concerned as to why people keep on pushing the idea it should be expensive. When in reality it should not be. Yes, any company will try to make the most money, but as a consumer, we are also informed and based on that, we should get the value based on that as well. If I am over paying because everyone simply thinks it should be over priced, then thats not increased value and its due to the consumer being misled.
So the only reason left for the much increased price, is that because we are 'early adopters', which imo, we are not.
Where did you get those lights behind you?
What are those lightsabers lamps you have in the background?
Great!
If they make 8k 65 inch qd oled in near future can they cut it in 4 to make 4 32 inch monitors 4k?
Thanks for the video. I’m more excited about micro LED.
I have the micro led iPad Pro and the iPhone 12 Pro Max which is oled. Nothing compares to oled in a pitch black room. The white Apple logo for instance illuminates as if it’s floating in midair on the oled, but on micro led there’s what is called a blooming affect where part of the brightness of the image bleeds over to the rest of the screen. Micro led does produce deeper blacks and sharper images than standard led, but it still pales in comparison to the perfect blacks that oleds are capable of producing.
Still rocking my Hisense H8G. It’s been outstanding for my bedroom.
Can we get an updated list of recommended soundbars to include sub 1000$ models .
QLED - expensive
OLED - more expensive
QD-OLED... yeahhhhh, gonna have to sell a kidney AND your firstborn child
Wait, I just have a question, at the end he mentions something like "QDEL" and the concept sound very similar to the original QNED idea from Samsung, is it the same thing?
They are not the same thing. QDEL = quantum dots convert electricity directly into light, no separate backlight is needed. QNED = quantum nanorods replace the OLED back light in QD-OLED displays.
@@matthewhendrix6821 Thanks for the answer, and holy crap didn't event knew they were working on the particles themselves being powered, this shouldn't requiere any backlight or color convertion layer, wouldn't it?
Do you have more info on the topic? Can't seem to find it.
@@sebasnu1 that's correct. Quantum dots emit specific wavelengths of light when they are electrically charged. Right now they are changed by light but they can be charged with electricity directly. That's QDEL. I'll be keeping my Sony A80J until QDEL is affordable.
In my opinion, high end CRT are still the best looking tv ever made. The industy been playing catchup for the past 15 years or so
How does QD OLED differ from Evo Panel by LG which is now in its 2nd generation?
I've just got Vizio p series quantum x for my birthday and now there's a new Qd oled ...I've never bought a oled before it will be my next tv for the next 10 yrs
At 10:17 did you say Sony’s qd oled tv ?
The panel being used in a monitor display is essentially a stress test scenario for any possibility of burn-in in TV units
Samsung s90d can be woled or qdoled. Its an absurd. Butt is there a way to know which one is when buying?
Quick question samsung q60b..70..80b vs lg oled. Which one should i go for?
Sony Bravia A95K QD OLED on discount now better than LG WOLED TVs this year and last or you could get discounted A90J or A80K
awesome Korean technology! between LG's OLED and Samsung QDOled, we have technologies that give us true black levels. . . exciting!
dude how much is the sony a95k going to cost? i am wondering if a 2nd gen mini led tv (first from sony, but prob samsung panels), will be good enough.
Samsungs QD-LED is starting at $8000 LOLOLOL soooo
@@TechCody113 really? is that how much it's going to be?
@@GordonJones88 the 8K version or 4K?
@@Harlizzlee so the QD-OLEDS, are gonna be starting at $8000, miniLED won’t, I’d say we should see the miniLED X95K maybe around $2500-$3000 for 65inch
What about sensitivity to direct sunlight?
Will it have less burn in potential then conventional OLEDs? The same? Worse?
Well explained.
But tbh, I just can’t get excited about TVs anymore, no matter how good they get. This used to be something I was really interested in, so I stopped to think on why this is. I guess I’m just over TV’s. I can’t see a use case for my family anymore. Thinking back on it, we turned on our big TV once in the past 3 or 4 years. Usually, we just use our large-format iPads to watch content. Everybody gets to watch what they want and when, and nobody has to put on their eyeglasses. We can get everything we want as far as shows (but we mostly watch CZcams these days), and I watch sports in apps, and get stats and other data along with the video feed.
I could see this being more exciting for PC monitors perhaps. But I think those days are numbered too. Once they really get VR headset technology locked in, that’ll be the death of large-screen displays. And while you can use them to simulate a large 2D screen, I think it will eventually lead to the death of fixed-view cinema as an art form. I think we’ll end up with theater making a comeback, except you are on the stage with the actors, able to look around at will. And it will revolutionize sports viewing. Imagine being able to choose between a pitcher’s- or umpire’s-eye view of a baseball game in 3D, as if you are right there? And of course it will be a game changer for video games, a revolution that is already in the early stages. I have high hopes for the Pimax 12K that is in the works, but even if that turns out to be underwhelming, somebody is going to figure out the tech soon.
So, I guess I’ve shifted my thinking of video from a big piece of furniture to a personal consumption model, similar to how most people have shifted with audio, moving from large living room-based hi-fi stereo systems to Spotify and Apple Music on headphones, smart speakers, and in the car.
Legitimately try having one screen on in each room. Makes you forced to be interested in each others hobbies when one person is in control. Even if just for one hour.
So if blue layer decreases its performance and less blue is seeping through, the other colors will also dim to match the ratio? That means that the TV will just get dimmer as it wears out?
Dave Rubin from The Rubin Report called. He wants his voice back. You guys sound almost identical, to the point where it is spooky, but also glorious.
Blue material USED to wear out the fastest. That isn't the case in recent televisions. that's like early 2010's news. they've updated the material since then.
On that corrective note, LG OLED's are actually 3 layers of OLED sheet. One whole sheet of red, one whole sheet of blue, and one whole sheet of green. These layers are STACKED to create "white." Then they use really bad color filters that lose a tons of brightness to re-create red/blue/green. With as you said, the 4th pixel left alone to be "white" and shine right through.
The samsung side, its ONE LAYER of all blue, with quantum dots on top. which create red/blue/green. there aren't layers like on LG based WRGB displays. and since quantum dots are insanely high quality, more light passes through, thus higher peak brightness.
just saying.
I have the qn90a beast brigh tv flws in dse and motion but maybe that can be fix the motion in a fiture firmware so hopefully but i like my tv 75 in my bedroom yes im crazy
I want to see how burn in works with the supposed upcoming computer monitors. Sounds too good to be true
I'm probably the most excited about this QD-OLED technology and how well it's going to perform.. what I don't like is gonna be the price of a 65" tv and basically with everyone (almost everyone) wanted to go bigger this is going to hurt the sales of this TV. I feel at some point Sony is going to have to take the hit and loses like it did with the PS3 and eat the cost and lower the prices. Just my thoughts.
I’m worried the price of these are going to be beyond insane
Lovely picture 😃 😀
Lots and lots of love from SONY 🥰😍😘
Thanks 🤍🤍🤍🤍
Do you think the Sony QD OLED A95K is going to be way more expensive than the current A90J?
Yes, most of the informed guesses that I’ve seen are somewhere between $6-8k for the 65” A95k. I’m guessing that it will be closer to the high end of that range. Hopefully, prices for this technology will fall in a few years.
How long is your “nice long time

Waiting for Micro led ... 🔥🔥🔥🔥🔥🔥🔥🔥
My CX LG OLED from last year is great. I’m happy with it for probably another 5 years ( I think ) But the ye olde PC monitor is a different matter. That Alienware QD OLED one I will definitely read reviews with interest. And if it’s there I think I will jump.
I Hi Caleb! as always, a fantastic and insightful, easy to understand narrative on new TV tech.. I have been a stickler for perfect 24fps viewing of movies and waited almost 8 years (bypassing the entire LED TV era). I jumped directly from a Panasonic 50" Plasma TV (that still works like a charm almost after 10 years ), To LG OLED in early 2021. What are your initial thoughts on playing 24fps content on QD - OLEDs?
If you are not using your black frame insertion feature on your TV make sure to turn it on. It makes the motion much smoother and more "plasma like". I also suggest a little dejudder for 24p content. it really is necessary to make it look it's best, unless you like stutter :( I love my Oled, (c1) but it isn't as suited to lower framerate content as Plasma is.
How about 10k soon !?
I will still wait for the mini qd OLED
This just confirms that Samsung, the cheerleader of LCD technology, couldn’t get their TVs to match OLED contrast. It also forces the OLED enthusiast to concede their current TVs weren’t as bright as they could’ve been. This will probably be a good middle ground technology, but not the answer that micro LED seems to promise.
Let’s wait and see how much brighter QD OLED’s are first. I’m cautiously optimistic. Over promising and under delivering is simply too common in this industry.
@@brucecarter6205 I agree. And I only support micro LED in theory. It’s going to be so ridiculously expensive I wouldn’t buy it until the next better technology comes along to drive the price down.
I’ve always openly admitted that my LG C1 isnt as bright as I’d love for it to be. But coming from bright and blooming to perfect blacks is just the greatest
microLED is not the answer either, as it costs ~$100,000. Maybe in 15 years microLED might be affordable MAYBE.
@@zenon3021 I agree, and also touched on this and another reply.
great video as always!!! Looking forward to the A95K review...and with Dolby Vision on it, Samsung better jump on board too or they're gonna get left behind!
Hi, which TCL TV do you recommend in the 40 to 55 inch category
So there might actually not really be any chance of burn in.. And burn in is a misnomer. It's uneven wear (aging).. So if they can literally monitor every single pixel they can just reduce the brightness level of all the Blue pixels (the light source) to be all 100% even luminance and hence burn-in cannot be seen.. Because that is all what burn in really is. It's just that some pixels have aged and for example doesn't shine at 100% but at 97% and that difference between a the rest of the panel being 99% and the area where the pixels that are "burnt in" showing 95% light..
So imagine them lowering the 99% ones to 95% as well. You cannot see burn in/ permanent retention anymore..
The key here is how LONG the Blue OLEDs can last. If it is for many thousands of hours. There is enough headroom to do this over time..
Also a TV that is 25% less bright over several years you wouldn't even notice, you'd have to have the same TV brand new sitting right next to it..
So this could, if done correctly actually mean a Proper OLED that also doesn't have burn-in. Unless EXTREME cases. That's exciting if true..
By the time I can afford a QD-OLED it likely will be 3 years from now anyway and by then we would know.
What about flicker? I am one of the small percentage of people that are negatively impacted in the optic nerve by OLED screens. I wish I wasn't but I am. Will this help with that issue??
your issue is same with crt & plasma ?
@@ismiismael I never had the issue before. I bought a CX had it for 3 weeks and all was good. Week number four the amount of time I could spend looking at the screen started to decrease. By week 5 it killed me to even look at it. I am surprised that more people don't have this issue.
The thing is mid grade TV’s are sooo good these days there is hardly a reason to go for the high end ones. Soo many beautiful looking TV’s and great brands to choose from. Definitely worth going for a mid grade over a low grade tv though
dose samsung use lg panel in this model?
Nope but them off Samsung Display division who make QD OLED panels S95B and S95C same Sony Bravia A95K and upcoming A95L.
How is the viewing angle on these QD-OLED’s gonna be?
i like that jacket
QD-OLED is a good stop gap before MicroLED becomes main stream !
Mini led won't become mainstream ever
What do you think a 65" would go for?
$8-9,000
@@chadboomershine9796 damn u really think so sheesh
Caleb casually signals his status as a fence-sitting force user. "What?! Those old light-sabers? Yeah, I dabble . . . a little . . . light AND dark sides . . ."
In theory, if WOLED is having to drive the blue oled through a yellow filter, which creates a dimmer image, these oleds are probably being pushed much harder to get an acceptable level of brightness compared to the qd-oled counterpart. This would probably lead to a shortened life compared to qd-oled.
Close, but not exactly. In the WOLED, there's a yellow phosphor over the blue OLED which converts the blue light to something closer to white. That MIGHT dim the output a bit, but the real brightness zapper is the color filter, which converts the white-ish light to red, green, and blue. That's why the white subpixel is added in -- to brighten things up.
@@Caleb_Denison Yep, it's not filter, but a phosphor. In fact, that's how ordinary white LEDs work.
The thing I am curious about is LGs OLED phone displays. Their TVs use OLED with a white subpixel. Is that the same method they used for mobile displays?
