I just stopped using a TV screen as a monitor and when I went back to using my monitor, there's overscan that cuts off the sides of the screen. The only thing that fixed it was uninstalling the monitor drivers, but I got an error message that basically said my drivers weren't compatible with my video card. And when I tried to fix it, the overscan came back. What am I doing wrong? I just want to be able to see my fill screen without it being incredibly choppy.
