Sometimes when coming out of sleep mode, one or both of my monitors shows a screen full of snow (see below). It's not a problem, I can just powercycle the affected monitor, however, it's slightly annoying. I just upgraded from a 8800GT to 4870 (flashed). The 8800 did not have this problem. PS: I also get the same thing when my Macbook is hooked up to my monitor, so I know this is a common issue not a real problem with the 4870. Edit: Samsung 22" widescreen monitors, different models and they both do it--looks like this is the problem.
