I'm running Tiger on a 2.5ghz MacBook Pro (purchased april '08) and everything works perfectly and the screen colors/ brightness is perfect. In Windows XP however (running via Boot Camp), the screen has an annoying bluish tint that I can not get rid of. It is especially visible in lighter colors that should be gray or off-white. In the NVIDIA GeForce 8600M GT graphics card control panel there is no obvious way to fix this problem. And it is not a gamma or brightness problem- because even after adjusting those, the bluish tint remains. Perhaps this is caused by a lack of a control in XP and/or the graphics card for the moniter's color temperature on the LED back-lit screen? When running XP through VMware fusion however the screen colors are dead-on. Anyone else experience this or have any suggestions?!
