I'm running Windows 7 Ultimate 64-bit on a Dell Latitude notebook computer. When it is docked I have dual external monitors. My primary monitor is DVI and the secondary monitor is VGA. Recently I have noticed that my primary display is darker than my secondary display. I checked my brightness and contrast controls on both monitors and they are set properly. The weird part is that my mouse pointer is the same brightness on both monitors, but the applications and desktop appear to be faded on my primary monitor.
What would cause this? What settings should I check?
