Hello, I have an Nvidia GeForce 6100 and using XP. I also have a SmartBoard. my brightness settings are completely changed and are not good. I tried changing the settings at the Nvidia GeForce 6100 nForce 430 color correction settings. I cannot get any ideal, it's just way to bright, what do i have to do? I already tried my monitor brightness settings and the smartboard brightness settings. it does not matter. I think there are problems with the pixels. How can i fix this? Is there something wrong with my video card?
