I wasn't talking about colour sharpness, I was talking about a white/yellowish tint that cover the screen. I got rid of it by setting TV to use limited RGB. But I get crushed black now. But crushed black is better compare to that tint. I also get judder with DVD hardware playback. I just use the PC for recording stuff and stream it to PS3 for playback. Kinda workout in the end. Now if ATI or Cyberlink can used that 4850 for useful hardware encoding, I'll be happy.
