One day I turned my computer on, and I was unable to make any adjustments with my "3dfx color" feature (such as video overlay, gama, brightness...etc). Every other Voodoo feature works, but the "color" screen is completely "grayed out," can't do anything at all with it. I've uninstalled/reinstalled several versions of the drivers, software, and hardware associated with the graphics card and the monitor, but still have no solution. I'm thinking there's a setting of something somewhere but i have no clue!!!!!! Any help would be greatly appreciated
