Hi, I've just had sky hd installed, and I notice a major difference in picture quality with the sky box compared to my ati radeon hd 4300 series card. Why is this? My comp specs: The card above is connected via hdmi to a samsung 42 inch 1080i hd ready tv. Also installed latest drivers software. Have a tbs dual dvb-s2 tuner connected with two lnb lines. Cosair 550w psu. 3 gig ram. Windows 7 ultimate, using media center for satellite reception. I notice a better picture when I increase the screen resolution way above the 1024, but this makes the desktop small and awkward to read and the screen on the tv isn't covered, ie the picture is reduced. Anyone any ideas as to how or if I can match the quality of the sky boxs hd? Many thanks.
