Redmi book 15 pro - bios - working screen only in windows after replace lcd
#1
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, 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?

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

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.

Sorry if the post is off topic.
