It's 1920x1080p, 60hz, 32 bit color. It's a 24" HDTV, I got the idea from a friend who has the same setup, with the same monitor, although he had no issues. Right now it's connected straight to my 6850 though hdmi. I've had two other windows 7 laptops hooked up to this same monitor and didn't have the issue. I've also changed it to a lower resolution with a frame rate of 75 hz and a lower resolution with framerates like 59 hz, 50 hz, ect.
