I have a geforce 6800 hooked up through vga to my lcd television at it's native res of 1366*768. The DVI end is on my computer monitor. For some reason I get these weird, somewhat noticeable, lines that go up and down. It looks like magnetic interference almost, it's not easy to spot at a glance but when your watching a movie or something it get's extremely annoying. I've tried connecting the tv through vga to a few other computers and none of them seem to have the same issue, so i don't think it's the cable. I checked the refresh rate to make sure it's supported. Does anyone know if there are some settings I can tweak to get rid of this issue?
