I've setup my display settings so I get a good picture on my Panny TH50PF20 plasma via the ATI 5450 card & HDMI. However, if I watch a Bluray film using TMT (3 or 5), the picture is dark so I have to change the brightness/contrast and change it back again after. This is really annoying! How can I get it all setup so I don't have all this messing about? Do I set the plasma's to 0 and fiddle with the settings in CCC or both? Thanks.
