I have a Samsung Samrton 77DF monitor on NVIDA GeForce 2 MX/MX 400. The color is normal at 800 x 600 pixels 32-bit but as soon as i chance the resolution to 1024 x 768 pixels the color starts to turn green. I have change the video card already and installed an updated drive for the graphic card but to no avail. But the moment I set the resolution back to 800 x 600 pixels the color returns. What do you thinl is causing the problem. Please help.
