Re: Gamma correction in windows 7 (don't trust the built in test!)
What LCD is it, if you don't mind me asking? My LCD has a crappy contrast ratio, so my blacks usually come out grey or even have the weird bleeding effect. I posted this issue in The Witcher topic a long time ago with screenshots about what I mean. If it's a fairly new LCD, the issue isn't as prominent as it used to be, but it can still happen.
I get what you're trying to say. There's a ton of similar issues with monitors both LCD and CRT. You can have the same exact model side-by-side, and the color output will be different in most cases.
