INFOCUS 4805 and XBOX 360... paired together

Ive had my infocus 4805 for a year or so and I just added an xbox 360 to my system. Although it looks nice, I KNOW that I havent maximized the combo's potential... could it be the brightness settings? contrast? color temp? I know I have different settings for my DVD player and DVI cable box that really made the picture come to life, I would like to do the same for my xbox 360.

SO FOR THOSE READING THIS: what settings have you found to bring this thing to life? Maybe it cant look as good as it does on smaller LCD panels, but Id like to get as close as possible.... please post some advice, or point me in the right direction.

THANKS
