Tweaking the Mac Mini Gama for accurate color on HDTV when using DVI-HDMI adapter
As one reader noted in this article on xlr8yourmac.com, the muddy blacks you get when connecting a Mac Mini to a HDTV via DVI-HDMI adapter are caused by the difference in gamma space between PC and TV (0-255 and 16-235 respectively).
You could use the Gamma control on the Mac Mini to dial up the black to 16 and the white down to 235. As the author discovered in the Plex forum, a freeware software product called Gamma Control has created a preference item to solve this problem more simply in his newer product, Black Light: http://michelf.com.nyud.net/projects/black-light/
