The Mac Mini is crushing black, and the brightness control on the TV is set correctly and verified with my VP403 PLUGE pattern and a test disc played through the BluRay player. When I run the calibration wizard on the Mac Mini, one of the first adjustments is for brightness, but there is no slider to adjust the brightness. There are sliders on the other pages for gamma and white point. Maybe there is a setting somewhere in the Mac Mini for video vs. PC levels or an HDMI black level control (low or high)? Thanks guys!
