This problem is intermittent so it happens sometimes. When I 1st start the computer and turn on the monitor(Sony XBR6 40"). The problem is the resolution. The text is not as smooth as normal and is fuzzy. The quick remedy is to turn off/on the monitor. Also I think the same issue persists with a movie file. When I go from windowed player to full screen, the monitor blacks out for a split second and it seems to over scan and the player is slightly bigger than the screen size. Doesn't always happen but it does and is annoying.
 I thought I fixed the problem with some new codec packs I downloaded but it still persists.
 
 Any suggestions? I'm running latest 347.52 drivers.

Hi,
1920x1080 native resolution of the monitor. I had 2x480 with same monitor and I had no issues. I will try another HDMI and see if it persists....
