I have an issue with flickering green pixels on my U2711. It's not a major issue, and it comes and goes. I recently swapped out the video card thinking perhaps that was the issue but the same issue still persists. I have re-inserted the DVI-D cable on both ends as well.  All drivers for video card are up to date. The Pixels always seem to show up in darker patterned areas of photos, and move with the pictures when dragged around on the screen. Because they come and go it is difficult to trouble shoot. The only other thing I haven't tried is a new DVI-D cable. I'm hoping someone here has seem this before and knows what is causing it.

Thanks in advance!
