Here are 6 fixes that have assisted several users in fixing laptops with black lines on the screen. In any case, open the PC up by wiping out its faceplate. If you affirm that the issue is hardware-related, there are a couple of various ways that you can use to endeavor to fix the problem. If you see no horizontal lines on your screen shown, it means that it is a software issue causing the problem. Since BIOS isn’t an aspect of the operating system’s working framework, if you observe horizontal lines on the laptop screen, it demonstrates that it is hardware-related.

This key relies upon your laptop maker and can be found in your laptop client manual as well as on the BIOS screen you see when your laptop boots up. Using the F2 button works on most laptops. If you don’t have an external monitor handy then you can use your TV as an external monitor.įurthermore, to confirm whether the laptop screen issue is a software issue or a hardware issue, you could enter the BIOS screen settings to check.

Maybe the heat went to the screen, because it absolutely went bananas after I finished playing: like the screen got white like scratch marks that returned to normal after a while I did not worry about it since it just returns to normal even if it comes back for no reason. My primary hypothesis here is maybe because of how I closed my laptop while I played a game (while it was connected to my TV). I have a question tho, Do you know the cause of this? So if you want a solution, maybe just replace the screen or better yet just let the Asus technicians fix it. The technicians said they replaced the screen, and after using it for over a month, the problem never came back. It was fixed (for 3 weeks of waiting, because maybe shipping of the parts was slower due to covid?) and I am very lucky because the laptop had 1 week left before the warranty expires so I got it repaired for free. So the thing is I had no choice but to send my laptop to an Asus Service Center.
