========================

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.
