I just got a new TV(new to me) I seem to have fixed the more common issue with screen tearing by disabling my monitor and changing pixel ratio to 4:2:2, but there is what looks like screen tearing or some kind of blurring specific to the bottom 5% of the screen. Please help. I believe it has something to do with overscan because when I zoom it back out it seems to solve the problem(reducing screen size though of course).
