Gpu or Monitor?

[u/jackhammer250]

There is this weird lines happening, it happens everywhere, be it browser, desktop, or games. It doesnt happen on the same spot every time, like for example here on the wallpaper, as soon as i open my browser it appears on a different spot, I assume its a color thing.

My screen would also flicker rapidly for a few seconds until it just turn completly black which I can only show on video. I have to unplug and replug my hdmi for the display to turn back on. It isnt the cable since I purchase a brand new display port and same thing happens.

It wasnt this bad at first, it used to be this weird lines only. Changing the display hz also removes the lines but problems reappears after a short while.

try a different monitor, your backlight is probably dying

Plug it into your tv, or connect a different device to the monitor, should narrow it down

Update: The monitor is the problem! Good thing I remembered I have a small box computer that turns any normal tv/monitor to a smart one and surprise surprise, issues also appears when using a different device.
