"Subject: New software solution to an old problem
Mike, I wrote to you 3 or 4 years ago about the muddy blacks I was getting when connecting a Mac Mini to a Toshiba HDTV via DVI-HDMI adapter. One of your readers pointed out the difference in gamma space between PC and TV (0-255 and 16-235 respectively) which was the root cause of the problem. I then used Gamma Control to dial up the Mac Mini's black to 16 and its white down to 235 which solved the problem.
I was browsing the Plex forum and discovered that the author of 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/
The Plex forum reveals that even the newest Mac Mini with the Displayport-HDMI adapter still does not deal with this automatically. So Gamma Control or Black Light is still needed.
Thought you'd like to know.
- Paul"
Whenever this subject (display gamma, washed out LCDs, etc.) comes up I'm reminded of a (shareware) utility I used in the past (added to the FAQ years ago) - SuperCal visual display calibrator. (I'm no graphics pro but liked its interface and visual feedback over creating custom Colorsync profiles using OS X's builtin util.)
