check your screen refresh rate, on some monitors a higher
screen refresh rate causes extremely bright, washed out
screens...mainly on the desktop.
Using an old NEC Multisync 70 crt monitor, running XP Pro sp2,
on a Nvidia 6600 Gt, with a P4 630 3.0 Ghz cpu... I use a refresh
rate of 60. When I, or some software alters the screen refresh
rate to 75 or 85 due to resolution changes, the colors and brightness
of the screen is drastically affected...from normal to super bright.
just a thought...but hey...ya never know...wot?
