I had this with my MSI micro ATX board's onboard video.  The reds were 
way too low at first, but anything with somewhat high red was blinding.  
I tested this with (I think it was a program called colortest), and it 
showed no red all the way to about 75% and then it shot up 
dramatically.  It also looked like the the gamma on the green and blue 
was low.  I figured it was bad hardware, but I decided to get a seperate 
card instead.  I have installed beta nvidia drivers on my desktop and 
they do have gamma/brightness/contrast adjustments in a utility that 
comes with it, so I'm going to try that sometime soon, but right now I 
have a cheapo radeon-based card with tv-out and their drivers on it, and 
it works well as long as I don't switch to the console, otherwise the 
display gets messed on the X session.  If you want to try the beta 
drivers, they are on www.minion.de.
