I have an nForce motherboard in my tower using OpenSuse 10 with the latest Nvidia drivers for it.
Since I got my new laptop and had it sitting next to my tower's monitor I thought the tower display looked washed out and dull.
Tonite I remembered I had the nVidia X Server Setting gtk utility. I did a search for some of the settings to see what they did. Turning up the digital vibrance really brought this display alive. Wow! Too much looked funky but a setting around 20 worked well. Colors are much more deep and crisp now.
