Windows Vista Screen Resolution Problem?

Earlier this evening I upgraded my OS from Windows 2K to Vista, but now I can't change my screen resolution. The highest resolution that I can set my screen to now is 1024x768, but I know that my 19'; LCD is capable of 1440x900 because that was what I had it at on Windows 2K. How can I fix this? I've searched on the internet and I've had two people look at this, but still no solution. Any help would be greatly appreciated.Windows Vista Screen Resolution Problem?
