just picked one of these up and initially im more than happy with the quality of the picture when using it for games, photo editing etc. thing is when i go to play dvd's on the computer using media player, the picture looks like rubbish, quite grainy with huge borders around the picture when i select to view full screen. ive installed the software and drivers that came with the monitor, the computers resolution is set to 1680x1050. am i doing something wrong here? is there some settings that i need to change? any help you guys could give will be much appreciated. thanks
