I was using on-board 780g AMD graphics for a while and had a great HD picture quality on Panasonic plasma. I decided to upgrade to XPS-5670 board, to speed up gaming, but the factory-default video PQ on the 5670 look very pale and bleak, like a budget LCD of old days. I did not change the driver or anything. I tried playing around with brightness/contrast in catalyst, but could not get as good PQ as with on-board chip. Is there something wrong with the board itself, or I need o use some tuning procedure? I'm using DVI->HDMI cable for both boards.
