Question Compaq CQ-42 Display Problem

[shuvobd]

My Compaq CQ-42 laptop's display cut off on the right side.
previously my resolution was 1366x768
now it's showing 1280x800
this problem is everywhere like laptop startup, bios, and windows.
for this problem, I have changed the display and its flex cable. but the new and old both display's are showing the same problem.

then, I updated my bios to the latest version and the problem remains.

Did you make sure to get the cable completely seated correctly when you replaced the screen and cable to try to resolve the issue? A loose connection can sometimes cause that especially since you were having the issue beforehand, replaced those, the issue remains and it's occurring no matter where you are on the system. Being in the BIOS essentially has you in a pre-boot environment so it may be an issue with the physical connector on the motherboard or discrete GPU (if this laptop has one).
