Question Monitor Black Screen on both sides

[ZeroGlitz]

Okay so this happened yesterday.
long story short, my lil brother just got home from school. and when he turned on his pc, his monitor suddenly have a black screen (like the picture). And now im trying to fix it, i tried changing the cable from dp to hdmi, i tried changing the resolution, i tried changing the refresh rate, and the i already download the latest display driver. idk what happened here, and one more thing. everytime i turn on the pc or changing anything that realated to the monitor, it work for a couple of second but after that it went black again.
So what is going on here? what happened?

PS: sorry for the bad english

Welcome to the forums, newcomer!

To rule out your monitor being the root of the problem, hook it up to another system/laptop and see if the issue persists.

and the i already download the latest display driver.
Did you use DDU to remove all GPU drivers in Safe Mode to later manually install the latest GPU driver in an elevated command(assuming you're on Windows OS)?
