I have 37" which I assume is very similar to 42", of course the picture is washed out before you calibrate it at least in the ballpark. One thing I noticed with Xbox360, the settings are all over the place, I need different settings for playing regular DVD over component (way too bright) and different for HD-DVD and games. For starters lower the backlight to about 20% above minimum, brightness to 25% and rest at 50% and take it from there. There was firmware update this morning and VGA looks better now than before. I don't understand why Xbox doesn't have more advanced settings for Gamma, color etc. like every computer does, that would help to set profiles for different display types and even maybe share it among users.
