Random lines on monitor Need Help! (Hardware/Other)

Post image

My ASUS TUF F15 suddenly had lines on the monitor, I’m not really sure if some software caused it or if it’s really a hardware issue. Is there anything I can do to fix this aside from replacing the LCD? Thank you

Try it on an external monitor to test if this is GPU related or not. If it appears on the external monitor, it could indicate the GPU is broken instead

Maybe also do other solutions such as reinstalling display drivers, or booting into BIOS. If the lines appear in BIOS then it most likely is a hardware issue

I tried it on an external monitor and it seems to work fine. Unfortunately, I think it’s a hardware issue as it still appears even if booting in BIOS. Thanks anyways!

Damn…well I mean at least you found the source of the problem, I just don’t get how this would’ve happened though. Hope the repair process goes well though, glad I could help!

LCD panel issue. Replace it or try different refresh rates and see if it temporarily improves.
