I have a nvidia geforce4 ti 4800 se graphic card in my pc. I know this is a mac, forum, but hopefully you can help! The problem is, the second monitor I have hooked up, cannot get the colors right on the monitor. I have tried several monitors that I know are correct, but they all have the same problem. I am thinking maybe it is the adapter is bad? but any other suggestions is much appreciated. I cant stand the yellowish screen any more!
