    RedmiBook 15 pro 2023 Ryzen - after replace LCD screen work only in windows

    I replaced the screen and LCD ribbon in Redmi Book 15 Pro Ryzen 2023. After replacing, the image on the screen is only visible in Windows 11 - when the AMD drivers are loaded.

    The screen is backlit but there is no image in: bios, post, when loading windows, in linux (ubuntu boot from usb), windows 10 PE.
    When I disconnect the EDP connector from the board and connect the HDMI cable, the image is visible everywhere good, in the BIOS you can see 2/3 of the image, i.e. 1920 pixels out of 3000 pixels.
    I checked the EDID with the old screen - it is identical.

    What could be the reason for this display? Incompatibility between LCD screen and board? bad lcd ribbon?

    Is it possible to edit something in the BIOS, e.g. resolution?

    Bios is insyde, it can be edited - Insyde H2oeze.

    Sorry if the post is off topic.​

      Are you sure of the cable ? What was the problem with the previous cable? If it still work , test with it.

              The old screen cable was damaged during replacement. The new screen and cable have the same product numbers as the old ones.
              The strange thing is that the screen only works after loading the AMD drivers in Windows, if I change to the standard Microsoft Basic Driver Adapter - the screen does not work.​

                  Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
                  by Ryan.man
                  Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

                  My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

                  This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

                  iphone XS turns off when press on screen.
                  by smic717394
                  Hi,

                  I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...

                  Samsung UE55JU6800K half screen dark
                  by Chrissygizmo
                  Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
                  I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...
