- Loads of folks seem to be having an issue with getting the official Raspberry PI 7" LCD up and running so I got one and have put together this detailed video (Well 2 videos really) showing how its done
EDIT
***********************************************************************************************************************
I accidently had the ground cable from the LCD on pin 8 and not 6 on the PI Header. Please make sure you use PIN 6 for the ground.
***********************************************************************************************************************
First video deals with the assembly only with closeup pictures to help you understand where the cables go and how they fit into the connectors
The second is a short test of the display using Raspbian 1.5.0 and we add a Virtual Keyboard.
Some people have tried to put them in wrong, previous instructions I have seen do not always make it clear so mistakes are made. I am hoping that my video will help to clarify everything
You can get these displays from numerious places including at the following links
RS-Online uk.rs-online.com/web/p/graphic...|acc
Newark/Farnell :- canada.newark.com/raspberry-pi...
Raspberry PI SWAG store :- swag.raspberrypi.org/products/...
PI HUT :- thepihut.com/collections/raspb...
and many others
NOTE: there was a mistake in my wiring to the PI, I accidently connected the ground (Black) wire to pin 8 of the PI instead of PIN 6. It should go to PIN 6.
This did no harm in this case as I had not enabled the serial functionality but it should be noted that if I had, It would have resulted in a short on a PI output pin. this may have caused damage. I should have said the third pin down not 3 pins down from the first. Sorry for an y confusion - Věda a technologie
This was so helpful. I am in a group who does coding, and they didn't connect anything properly. This video and the next in the series set me straight. Thanks so much.
Thank You! This is the best, most complete, and most informative instructional video for setting up the 7" touchscreen. I followed the step by step instructions to hookup my Raspberry Pi 3 and it worked almost immediately. Thank You again...........
Your welcome and thanks for the positive feedback
5 years later and still informative...thank you.... great job .. trying to get the 2nd part but can't seem to trace it.
Glad it helped!
Ordered this on Sunday along with the v2 of the camera module (with 8MP) and waiting to get it tomorrow or on Wednesday. ^_^ Thank you for this tutorial. Very neatly explained, love the zoom in whenever you are connecting stuff and most of all I really appreciate it that your hands are not in front of the camera. Surprisingly enough many tutorials are actually bad just because of the fact that the person who's doing them is covering the view with his/her hands which renders the VISUAL part of the video completely useless. :D
This was a lot of help to get my up and running, thanks!
Thanks for explaining the ribbon part I was all night trying to figure this out until I seen this video cheers
Thanks, mate, for the video. Your explanation was quite precise and very clearly done. Keep up the good work. I found the video to be quite helpful.
much better tute than the others as the inclose camera work is much clearer. The other vids put the ribbons on the boards in a flash and i'm WTF?? good stuff
Very nice informative video, with GREAT resolution. Thank you
this helped me fix my black screen problem! thanks!
Concise. Well presented. Subscribed. Great job.
so much better than the other video I tried to use
Great closeups very useful.
well made and so very good information. thank you for this video. you made it supper easy to follow. this is the perfect size of screen for me.
Thank you for this. Is there anyway to edit the actual video regarding the pin 8/pin6 correction to avoid others making that error please? I only inadvertently read your after-note. Fortunately I did though! phew!
Really love your clarity and close ups. x
Thanks a lot Peter. I had a question regarding if it is possible to run this whole thing via battery power? Do you think it would be feasible to power the screen, the pi and an arduino using a battery?
Battery power is perfectly doable
Very clear, good information.
Almost watched the full video until I see you are using a 50 pin connector. I have an LCD with 40 pin for the display and it has a digitizer with 30 pins. The part numbers are Wtl068601g02-18m wtf0686lg40as1-v5 for the display and WJDR6870-V3 FPC.
I want to use this 6.5 display with a raspberry pi but I cant seem to find the right connector or conversion board. Any ideas would be greatly appreciated.
If we still put all the colored cables and we do not use some of them, will it affect pi or just sit there and do nothing, cause im thinking of putting all, cause why not ??
thanks！ great help ！ now i finally know how to install the pins
simple and effective video thank you so much.
Very clear how to do it. Thanks.
Great video - thanks very much. I'm just starting with some Windows IoT stuff. Important to note the incorrect Ground Pin.
Will I need a fan or heat sink if I am going to put it into a case? I'm using this raspberry pi for a firewall setup for my senior project
I have never needed a heat sink on any of my projects so far, and a few are inside cases, it is something that is easy to add though if you want it to be that extra bit cool
Is the ground not connected to GPIO14 in the example shown? That looks like pin 8 to me.
Hi, so if I refer to your video, you can't plug a (for example : ) RFID card to the GPIO just because you already plugged a few pins for the screen on it ????? i'm screwed in my project so ? I just want the screen and an rfid card... there is one GPIO 40pins... so it's dead ?
Not at all, there are only 2 pins of the header actually needed and they can be done differently, Such as feeding both boards with USB Power. The only thing mandatory for the screen is the ribbon cable on the side of the PI. As long as the display has power via its USB it will work. The PI can simply be powered through its normal power connection.
Is there anyway just to get the control board? I have a 7" touch display that i bought but its for a arduino mega. It looks to be the same type of screen and touch display so i'm wondering is there any way just to get the controll board or if the schematics for the controll board are available with the rom driver.
Not that I am aware of and it would probably be cheaper to get a whole display, try looking at www.52pi.com for more economical displays that work with the pi
Pi3 must have a different pin config. I am glad i checked on the pi site. 1 is 5v, the next is also 5v, the third along is ground. i did have my pi3 wired as per yours.....glad i checked before i powered it up.
The same is for pi2 but unfortunatly I didnt doublechecked so it was blank screen, wondered etc... Updated os ... at the end doublechecked the ground connection to the pi. Its good that nothing had broken. Its also intresting that the power supply was connected to screens power in (as in video) and when I connected to hdmi the pi worked normal. i wonder how was the circuit closed? the screws?
Yeah I was thinking the same thing. watching the video thinking to myself, wtf? those are not 5v pins... lol
I just powered up... nothing happened (well, a red light). Did I break it? How do I fix what's wrong in the vid?
Peter, fantastic and very helpful video tutorial, Sir! Thank you!
I was wondering if I might run a question by you. You mentioned that there is a USB power feed as opposed to using the i2c connectors, which, as much as I would rather use the method you've illustrated here, I might have to resort to, as I will need to affix a hifiberry i2s sound card to the GPIOs. If I use the USB method instead, will I still be able to use the touchscreen functions?
Sorry about the 'NOOB' questions...
Thank you for your time and help.
Best,
Chris
+Dolce Dolente The Touch screen works through the LCD cable so it will not be affected, just feed power via 2 USB leads, one to the Screen, One to the PI
OR
power the PI via USB, then using one of the PI usb connect a very short USB to the touch screen
Either way, now the GPIO header is free for any card to be connected
If your ok wih soldering, you can also connect the power to the underside of the PI GPIO instead of the top
Thank you so much! I just placed an order for one. :)
Can I use an old lady touch screen from an old car stereo with backup camera? Like scavenger style? Even if I could get display only it would be neat
Well the PI does have HDMI and composite output, if the display has either of these then possibly
Does anyone know what component U2 is between resistors R8 and R11? I made a mistake in the voltage input putting 12v and then this U2 burned .... I couldn't find any schema or datasheet
whats the name of the connector for the lcd screen
cool. If I understand it correctly. I don't need to use the GPIO pins if I use separate power supplies?
I use a T-cobbler so all the GPIO pins are "occupied"
Tor Ivan Boine that would be correct
Hi, are you sure that it's the 4th pin for the GND? for me, I think that it's the 3rd pin after the 5 V pin.
You are correct but it is already edited in the video and all over the notes in the post.
Great video! Thanks
Do you know if i can use that connector for a regular LCD laptop? With (obviously) the proper cable?
It uses an industry standard interface utilizing differential pairs (Very High Speed) and a I2C bus, I think the pinout can be found on google, if the LCD you want to use has the same then it possibly will work
Hey Peter! I got the display and followed the steps, but the display is not lighting up. I have tried using commands sudo apt-get upgrade/update, but it is still not working. Do you have any idea what may be causing it? Also, is it normal to have black lines across the width of a unpowered screen? Thanks!
+Jun C Re-check the wiring, especially the flat cables between the Display and the adapter board, have a re-watch of the video for assembly and look where I show the closeups of the way they attach
Almost every instance I have seen so far has been identified as an assembly issue. If your booting from a new image (2016) then you dont even need the update/upgrade stuff to get it working
Hello sir. Can I find all of these tools you used in this video as a package in order to not buy piece by piece to gather them?
The only tool I used was a cross head screw driver?, all the parts are included in the Official PI 7" Display kit.
What specifically are you referring to ?
ive got a 7inch display from an old portable dvd player. will it works with raspberry or do i have to buy an original raspberry lcd ?
Probably not, certainly not in a timely fashion. Many people have tried with varying success but at the end of the day it often takes a lot of time and effort for little progress.
Could it be done... sure, How long will it take, I have no idea as there is not enough detail but it will be time consuming and considering you can get a display for well under 100$ that will work right away, is it worth it, probably not.
I have a pi4 and this screen and I can't find any Information on what the sda and sec pins are for. Do you have any videos explaining those pins? Thank you
i dont but why do you need to know, the screen simply plugs into the connector designed for it and then you add the supply and thats it. all should be working
This is an excellent video and thank you very much for making it so easy.
I got a Hifiberry Digi+ Pro board which sits on top of the Pi. Will I still be able to connect the red and black jumpers or will /i need a hack?
As long as the stack still allows access to the pins it should be ok (Even if there the pins on the HiFiBerry.
The worst case is to solder the wires to the PI, or do away with them and utilise both the USB power port on the PI and the Display,
Thank you very much for the prompt response!
So I could possibly run a USB A male to micro USB cable from the USB ports of the Pi to the micro USB input of the display board?
In theory you could but it would be better to run two USB A to micro USB cables from a power adapter to each board. rather than through one board to the next. Doing it your way will cause the pi to be supplying all the power through it so you may get the magic rainbow showing up on occasion.
You won't break anything doing it the way you suggested, or should not anyway.
Thanks for your suggestion Peter.
The reason I want to power both units with one PSU is that I'm using an iFi 5V PSU which may not be xactly a linear power supply but it is close to that. So preferably I would want to feed first my Pi with DC and then the display board by one of the ports of the Pi. If the display consumes less than 500mA, then it should be doable.
Peter, I want to install the pi3 and screen in my 55 Chevy Sedan Delivery console with the 7" touchscreen. I'm a pi newb and 60 years old so a detail video or answer would be appreciated. I would like to incorporate a backup camera but most I've found on Amazon have a yellow red rca connector. How would I get it into connected? I also want gps with a mapping option for the trips I take. Can you help me out?
The Raspberry PI does not have a Video input.
The yellow RCA connector will be a composite video output from the camera, the red one most lightly is power
there are many "Non" official screens available that incorporate many different video inputs and this would allow the PI to feed to it and also a backup camera, for example this
www.ebay.com/itm/7-inch-LCD-Screen-Display-Monitor-for-Raspberry-Pi-Driver-Board-HDMI-VGA-2AV-/171280831162
now I have never tried this one so can not guarantee anything about it or the seller. I do however have a similar 10" display I use with a PI and it works well, I am not sure if it has the ability to auto display the backup camera (AV Input) but many of this type do and it could be trigger by a switch on the gear shift for example.
I would suggest a DC-DC buck converter to power the PI, this will allow the car 12V nominal supply to provide 5V to the PI at a decent current and also efficiently.
For the maps thing, I am not sure. this you would have to search for PI software that could do this for you, if you planning on using with no internet connection then the software would need to include all the maps as well. A gps is available to work with a PI that can give the co-ordinates needed for the software.
I have never built all this into one system but I dont see why it should not be possible, also dont let 60 stop you, im very close to that and have no intentions of stopping any time soon, in fact i'm just getting started :)
Peter Oakes haha, 60 is not stopping me. I plan on using my cell phone hotspot. put your thinking cap on and make us a video! I'm not getting any younger.
The only I seem to have with mine is that it displays a small color cube in the upper right corner. Do you know how to remove that?
Great video. I didn't know about the other jumper wires and that you can't use HDMI when using the LCD. How does one use the HDMI then with an LCD, is that never possible?
Great tutorial Peter as usual. Thank you. I have trouble getting sound out of pi3. Can you help ?. Most of the tutorial here did not benefit me. Appreciate it very much.
+Karim Ismail Try this www.raspberrypi.org/documentation/configuration/audio-config.md it may have the answer
This adapters are sold separately?
do the extra 2 wires help control screen brightness? i just got one of these for my birthday but have no idea how to turn that down.
No, the extra two wires are i2C interface i think and not related to screen brightness. I have not figured out how to adjust that yet. If anyone knows, please let us know. Thanks
raspberrypi.stackexchange.com/questions/46225/adjusting-the-brightness-of-the-official-touchscreen-display/46229#46229?newreg=7e25b5cd451044de996cf4eed13414e4 try this. it works for me.
how do you connect all the pins correctly so the display isn't upside down? I connected everything like you had it in the video, but my video was upside down. How do you fix this?
Oh, in my case a very technical change. I turned the physical screen upside down :)
but you can change a config setting to rotate the display if you want.
If the display is working then that's all the physical stuff done correctly, the rotation is totally covered through a config file
sudo nano /boot/config.txt
add lcd_rotate=2 to the bottom of the file
press CTRL+X and y to save. And then
sudo reboot
Thank you
Did you ever check the quality of your video?????
thank you so much
Quite good. I appreciate the mistakes followed by correction. One nit: I wish that you hadn't brought up Windoze in this assembly. That could have been a separate video that does an addendum and you could have mentioned that. I would recommend that folks first get their displays working with Raspbian or another Linux OS.
lol... isn,t the cat in the background an ESD hazard? But, I will say that your bench looks immaculate. Great tutorial.
I have an esd strap as a collar :)
It so helpful
Loved your video, I have an issue. I purchased a Raspberry Pi 4 Model B along with this exact touchscreen which seems to be slightly updated as the display board says 1.1 instead of your 1.0 but the connections are the same. I need some help because I cant seem to narrow down this issue. I downloaded and copied over the latest version of NOOBS to my FAT32 formatted microSD card. Made all the proper connections from the display to the board exactly like your video but when i plugged it into power, the raspberry pi turned on but the screen did not turn on at all. I read that you dont have to use the jumper cables as it can recieve power from the Pi itself so i just connected the Pi to USB-C. Further research said apparently that I needed to flash the .img file of the latest raspbian as NOOBS doesnt have the drivers if you just drag the files and try to run it on the screen at first boot. However when i downloaded raspbian and flashed it once again to my microSD card I still get a black screen, no backlight or anything. Any help would be appreciated, thank you!
Both the display and the PI need power, you can either plug in usb power to both or power the display and use the power jumpers as indicated from the GPIO strip from the display to the PI, and of course the flat flax cable from the display to the PI. if you have tried all these then it is possible the flat flex is not the right way into the sockets on the PI and or the display, there are only connectors on one side of each socket and if the cable is upside down then the PI wont even detect the display is there. Hope this helps
theBreadboard Thanks so much, the SmartPi case I was using came with a USB-C splitter, plugged it in, redid the flex cables and all is working perfectly. Thanks so much for the help!
@@TravelsOfMK8ITRA1N Your welcome, glad it all worked out
I lov it
Hi, my screen came with a Y adapter to power both the touch screen and the Pi Do I still need the jumpers from the touch screen to the PI. if So which jumpers needs to use?
If the Y adapter is providing power to both the PI and the screen then they will have a common ground already so you don't need the jumper wires connected. Just the flat cable
what is the link to part2 of this video. looking to get the on screen keyboard to appear.
do you know where I might find that setting on raspbian?
To do this, open /boot/config.txt in your favourite editor and add the line:
lcd_rotate=2
Hi, does someone know you know how long is the boot-time between the plug of power and the image ready on screen? Thanks!
Does this work with the Pi Zero? Should be the same ribbon pin out, right?
PI Zero does not have the same size connector so I doubt it will work, also the PI Zero only has a camera connector, not an LCD connector so the official PI screen will not work with it
Thanks! I was hoping that the ribbon connector was the same and I could get a slimmer version of the screen+pi3.
I Followed this exactly (I only used red and black wire) BUT it didn't work. I manged to start the display but it's just a white screen that won't disappear. What's wrong??
please recheck the orientation and fit of the flat cables. This is the most common source of issues when assembling the screen

@Peter Oakes THANK YOU THANK YOU for posting this. You are a "life saver" I never would have been able to do this without your assistance. (in total sincerity, if you have a private website with a "tip Jar" please advise. Would be most gracious to "tip" you.
I followed your instructions to the letter. The Problem I';m having upon inserting a Power Device (the Power Pack that came with Rasp[ PI3). is, the screen only shows Vertical (up down) lines of color.
*FIRST* I FULLY APPRECIATE you can't take time to diagnose/help my issues.
However, do you have a suggested URL/SITE?Resource to go to when "Tech Specing" it?
I wouldn't even know what to Google for (as to what is wrong) is why I ask.
I have gone back through and re-seedall the stuff. (FYI! *THANKFULLY* the "Latest" version of Element14.com Shipment. They were kind enough to ship it with the "Board" already installed to the Display. All I had to do was the "Ribbon" and Color Cables. WOOT! Mount the PI to Device.
THANK YOU SO MUCH AGAIN! .
NEVER MIND! WAS A "SEEDING" ISSUE! Thus I'd Highly Reccomend people checking those Ribbon Cables!
unless you running a program to do that, I would say your display is faulty, I have never seen this on the PI3 display.
If you have verified all basic assembly instructions then there is nothing really left to go wrong aside from a faulty unit
I have seen it with LED/LCD displays where there is a fault with the controller or the actual connections to the display (The glass), either of which you can not fix. I would suggest contacting the sender and ask for a replacement.
lol, just saw your later post. I guess it was down to checking the basic assembly.
Happy it is working for you.
It looked like you put the ground cable on pin 8 and not 6. You said "...three down from pin 1". I think you meant to say the third pin. The GPIO pin-out chart I have shows pin 6 as ground.
+kc6tyd Just checked (Its still wired here on the bench) and it is indeed on pin 6 (3rd one down), and your correct regarding where the ground pin is, as is your diagram
Ok, I just watched the video again and you have the ground on pin 8 rather then 6. Unless the GPIO is different on your Pi. I have the Pi 2. Very informative video.
You are correct Sir, sorry I for a moment thought you were refering to a different video, well spotted. As it happens, because I was not using that pin (Pin 8) and there was a groud via other wires (LCD Connection DVS Wires) it still worked without an issue, I have now corrected the connection on my bench.
Good catch
Thanks for the instructions.
thnx
thank you! You got me up and running!
your welcome
Ok, some i followed someone elses instrcutions saying to plug it in to the #8 pin. i did. did i just fry my rasp? plz say no
I accidentally put ground to pin 8 in this video without issue but there was a proper ground via the ribbon cable too and it still all worked, I noted my error in the comments and on the video. if you had a proper ground and you connected a 5V power to pin 8 (A GPIO PIN) then there is a possibility you destroyed the GPIO pin at least as there 3V3 tolerant, not 5V. Have you tried connecting the correct voltages to the pi on its own and did it work ?
Even though you made the wiring mistake, there will be no harm in correcting the wiring and trying again, try the board with out the display connected to be sure. The display hopefully should be OK, please let me know the outcome
Sorry for your loss if it is not working, Phew a disaster averted if all works :)
Isnt the a way to extend the distance between the display and the pi without mounting it to the back of the display.??
You would have to to get extension / longer flat cable, not sure where to get them but that would work, you would also need to power the PI and the display separately I would guess due to the increased length. Something like these should work www.adafruit.com/category/800
What about the other connecter's?
The power can be directly connected to the PI and the Display via the USB connectors. The controller for the display will still need to be on the back of it, the PI can be distant, this way only one extension cable is needed. this also means you dont need the single colored cables, just the white flat cable.
“If you liked this video give it a thumbs up but if you didn’t well then don’t” Haha!
Was looking at getting one of those displays for my Raspberry PI. Can you possibly recommend a US source?
+hankus253 its right in the description... Canada.newark.com, or just go to Newark.com and pick your region
+Peter Oakes (TheBreadboardca) Duh.. Thanks Peter, guess I was having a senior moment.
we all have those from time to time :)
can i use raspberry pi 3 for the LCD display?
Does this work with the raspberry pi 3?
yes
Dear Sir,
It was shown in the video at 15:00 min that Ground Pin was 3 pins away from Power supply which yields pin no. 8. But on RPi the Ground is Pin No.6. Please verify.
you are correct, there is already a warning popup added in the video stream and a note at the top of the description regarding this. Thanks for pointing it out though and being observant... keep it up.

your a big minions fan
What if my screen is a psp screen and the cable thing is too big.
The only answer I can give to that description is "It wont fit" :).
Basically the DSI connector needs to go to a DSI interface that converts this protocol to one compatable with the LCD screen, this can vary between manufacturers.
The easiest solution is to use an approved LCD for the PI DSI connector or use one of the many inexpensive HDMI/Touch combo LCD screens available.I have an example of both and it works great in both cases.
It is not worth the effort to try and convert a non compliant display from say a laptop or picture frame to the PI
I have the LCD v1.1 and the raspberry pi 2b but it's not working
are you using the latest version of the Raspbian ?
Peter Oakes I think so but I'll double check thx
I bought the same one but my screen is glitching what should I do
I expect you have a much later version if you just got it, I would suspect the power first, then connections
Thank you
Does it have an Audio?
No Audio
what about us who use kali or rasbian tho?
This video shows Raspbian ?, I dont know Kali though but i'm sure there is someone out there who can show how its done.
There is a small mistake in video, the ground should be connected to the 3rd pin and not the 4th to the pi's gpio.
Read the description
does it work with pi3
Yes it does

What model of display using here?
This is the original and official Raspberry PI 7" display
Why so many ribbon cables? I though they were abandoned in the 90s. I do not like those.
not at all, back then they were still with real wires all in parallel, these days there mostly flat flexible circuit boards that can have many more wires per inch etc. but those older type cables are still arround, just look in any modern printer and you will still see them
It is ok when they are used as part of something. But some, espacially with bare metal contacts rather than the frequently used clips which you can find in modern pcs, are in my view bad for cable management.
are you american or4 english?
English but moved to Canada back in the last century :), 1993. NOT American :)

Hi I am new and started using raspberry pi 3 with
RASPBIAN JESSIE WITH PIXEL and install Raspberry Pi 7” Touchscreen Display. Screen Resolution 800 x 480 pixels
I am facing a issue when i run Qt Creator 3.2.1 and click maximize icon, not able to get full screen layout of the application as few of part of the qt is partially hidden.
i have followed the instruction of installation from this link below
www.element14.com/community/doc ... en-display
touch is working perfect and there is no black border from the screen. Its some thing else i am not able to figure
If any one know to resolve this issue pls help me out to achieve the display to display full screen
Thanks in advance and waiting for answers.
I like the video and voted "Like". I followed your steps but my screen does not light up. I'm using Raspberry Pi 3 Model B (I corrected the pin connectors, but i had a go with your pin connection system) Hopefully i have not burned the screen. I've searched on serveral forums for the solution but i couldnt find any. Hopefully you might have an answer.
I wonder if i need to use a micro sd with installed OS, becouse i read something about it here: thepihut.com/blogs/raspberry-pi-tutorials/45295044-raspberry-pi-7-touch-screen-assembly-guide
I've ordered a 2.5A charger/adapter.. Becouse right now I'm only using a Samsung travel adapter with 5V, 2A output.
The raspberry pi 3 model b starts with 3.5" TFT display + PiDrive connected to it, without a problem.
Thanks for any good/decent tip/reply!
Best regards
certainly using the latest Raspbian will ensure success from an OS perspective. If you have added drivers for the 3.5" TFT display then the console may have been re-directed to that display, even if it is not connected. As a test to ensure the PI LCD is working, try a fresh SD Image from the latest Download of the OS from Raspberrypi.org.
I put plenty of warnings about the corrected pin but to add confidence that it is ok, not correct but ok, the reason I said it wrong was because I accidentally connected it wrong myself. It should not do any harm as the pin defaults to input and it was not used. In my case the display still worked ok, even with the pin connected incorrectly, as there are plenty of other ground connections through the flat ribbon cable.
Biggest cause of the screen not working is typically a flat cable not correctly inserted into a connector, next is a old version of the OS or one that has been configured for alternate displays. The PI does not currently support DUAL displays so you need to select / configure just the one you need.
Thank you very much for your answer. I will try again very soon. Waiting for new micro sd cards to arrive. Until then, have a nice one and thanks for your reply! You're great! :)
It worked like a charm with the 2.5A charger! Thank you very much mr! :)
You dont need. The jumper. Cables You.can. Use.a. USb. Cables. Frome. The. Raspberry. Pie
you could but then your introducing much more voltage drop as it goes through the pi and a thermal fuse before exiting out to the display. It may work but not the best way in my opinion
perfect perfect perfect!! I was in the wrong pins and didn't notice the pull tabs on the cable. THANK YOU THANK YOU THANK YOU!!
thank you so much
