Hey everyone, I recently bought a 2nd hand Mac Mini 1.5 Core Solo. I have it connected to my 24" Dell display via VGA (through the DVI adapter). It defaulted to 1680x1050, which looked fine, albeit a hair fuzzy. But when I increase the resolution to native for the 24" display, I get faint vertical lines all the way across the display. Looks vaguely like corduroy. Anyone have any idea what might be causing it, or how to get rid of it?
