715 - you said >>Settings, Control Panel, Display, then click the Settings tab, then Advanced, then GeForce or TNT, then Additional Properties, then click the Color Correction tab, then slide the Gamma slider up (mine is set to 1.6 for Aces High).
I tried following your steps to change the Gamma correction. For whatever reason, when I get to Advanced I don't see GeForce or TNT and when i click on Additional Properties there's no Color Correction tab. This is true for my computer at home and work. I even went to the Control Panel, Systems and picked the NVidia driver to change properties and there was nothing there either. I've upped my monitor brighness to 100% and bumped the contrast from 50% to 67% which has helped some. Still lookin for that Gamma correction factor...
