This only happens in World of Warcraft and only on my Dell 2007WFP. Notice the bright yellow band around the right side and bottom. It used to be a rainbow of colors and I figured it had something to do with my playing the game at a resolution under the Dell's requirements. I adjusted the rez up to 1680x1050 and it went away for a while but now its back and brighter. My vid card is an ATI 800xl, I don't think that is the prob since it only happens on the one game but I figured I'd throw that detail in just in case. Any ideas?
