VGA-out puts weird flickery lines on display

I have a Toshiba Satellite L335. I have tested two different monitors and have the same problem. When I plug in an external monitor, I can see weird horizontal lines. I bet it's doing a super slow refresh(something like the 40-50hz) but I can't prove it. Anyway, its basically on any white area what I see is horizontal(not perfect straight, sorta diagonal too) lines. Like not really thin lines, probably 1-3mm in width(and extending across the entire screen). The lines look like not black, just slightly darker. Just subtle enough for me to notice. I've noticed that working with the screen in this state affects me with headaches and other crap to do with Over Illumination. so now it's crossed the line from annoying to I-need-to-fix-this. I've tested both monitors on a different computer and they work fine on other computers(at the same resolution and refresh rate)

Sounds like artifacts, which are a video card related problem. They are usually a result of overclocking the GPU, but you can get them without overclocking as well. Check out Artifact Tester for a better idea if you will need to replace your video card or not.
