From what I understand from the colorsync list (and my understanding could be wrong), the 2 different monitor
Gammas on the 2 different systems (Mac & PC) produce the same results, and that it's the video card
interpolation in the Mac that needs to be set to 1.8 instead of 2.2 to get the same resulting monitor
'illumination'.....Or something like that.
