"But... I ran the included Optimization Wizard for calibrating my display, and the Gamma wizard (where you drag boxes to adjust RGB) made my previous images very dark, too contrasty and saturated. I reset it back to the defaults, which makes it look identical to the settings I used with my previous driver." Yeah, I have an nVidia board too and I played around with the Gamma Wizard too one day. Got the same thing you got. Went back to the default too. Not sure what the Gamma Wizard is supposed to do, but it ends up just making a mess of things. As far as your gallery images, they look great using my nVidia default setting, ie not using the Gamma Wizard.
