My monitor is being weird
So what happened before this was I was using Google watching some YouTube and then my screen had like bars appear on the side like multi different colored bars which was green yellow and purple and then the yellow turned into a yellowy orange and covered the rest of the screen except for the sides and now it's blinking with horizontal lines how do I fix that because I have tried myself I have unplugged and replaced in the DisplayPort cable I have switched where it's plugged in and for some reason it's still doing that sort of thing when I don't move any window or anything on the screen the lines don't blink but as soon as I move anything like where an app is placed zoom in or zoom out or anything like that the line start to blink I would like to learn how to fix the problem because I don't want to be playing games and it looking like it's CRT monitor. The monitor is a Samsung LC32G5xT and my GPU is a Nvidia GeForce RTX 3080
