For some reason, there's no options for me to choose resolutions such as 1280x720, 1280x800, 1440x900, and 1440x1050, amongst other resolutions on my primary PC. When I try to set them as custom resolutions, they fail. However, in my older PC, and in Vista, I have about twice as many options to choose from, including those resolutions. I have the latest drivers, and tried re-installing them after using driver cleaner with no success. Looking at the inf file, those resolutions are said to be supported. What can I do to enable those resolutions?
