I bought an xbox 360 slim a week ago and everything was working fine, but today all of a sudden the quality of the picture went noticeably worse than before.
I'm using an hdmi cable and have the display set to 1080p. I didn't touch anything before that, the picture just went worse by itself. I thought It's the cable and i tried switching it with the hdmi cable Im using for my laptop - same result. The XBOX 360 logo at startup appears jagged and fuzzy and not smooth at all, dashboard text and pictures look very sharp and highly contrasting, and its the same with models in games (fifa 11, nba2k11). Also sometimes small white moving dots would appear on the edges of 3d models in those games or just across the background. Overall it's not that bad and its absolutely playable but it's not supposed to look like this and definetly different than the first few days.
Any suggestions?
Thank you.
