Half screen is black when plugged in

[abrinias]

System: Windows 11
Model: ROG GA401QC
Frequency of occurrence: All the time while plugged in
Reset OS: Tried to reset to factory settings, but problem persists
Screenshot or video:
========================
Detailed description：
When my ROG GA401QC laptop is plugged in, three quarters of the screen is black with only one quarter visible.
The black screen issue persists when in BIOS and when starting up prior to the windows login screen regardless of if the laptop is plugged in or not.
The screen is fully visible when the laptop is on battery power.
When I plug in an HDMI cable, the screen is successfully projected onto another monitor without the black portion (fully visible).



Solutions tried:
I tried updating all drivers and downloading/installing all windows updates
I tried resetting windows to factory settings

I think it may be a hardware issue and I'll have to send the laptop to ASUS for repair. Just wanted to get some community feedback.

@abrinias
If the same situation occurs when entering the BIOS, it may be caused by an error in the VGA card or the motherboard. I would suggest you bring back your laptop to our service center.

It can be one of several things. A defective screen, a broken or partially disconnected cable to the screen or a bad video driver circuit - in that order. You can try to replace the screen yourself. That's a risky task but if you follow instructions with the proper tools it can be done.
