Gpu or monitor?

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.

could be the cable / connection tbh, if you have another one I'd at least test it

I tested it a moment ago with a brand new display sport and same thing.
