My 19-inch acer monitor is showing all vertical lines as moving and jagged lines. It's very painful on the eye. I tried capturing a screenshot but the lines in the screenshot are perfect. So I figured it must be the monitor. Anybody have a similar problem? I tried fixing the refresh rate, focus and clock on my settings. And one more thing, the settings display is smooth when I press the menu on the monitor. 'Auto' settings didn't solve the problem.

My monitor has only a VGA input.

Have you tried degaussing </joke> ......or a different monitor/video card to determine if it's the monitor or video card?? –  Raystafarian Feb 4 '12 at 16:29

Simple thing to check: I've seen this before when the cable is not fully seated on either end. Check that if you haven't already. :) –  Garrett Feb 4 '12 at 17:11
