Make sure to check that your monitor is being listed and not plug and play - even though P&P should give you a higher res. Also do you have on board video? Possible conflict? You may want to install older drivers and make sure you are getting the Win 7 x64 versions from the nvidia site. Maybe "uninstall" the vid card in the hardware manager and then select detect hardware - see if windows will redetect the hardware and install it correctly. Or uninstall the Nvidia drivers, reboot and see what res you get with the MS drivers. Or download Riva Tuner and see if you can set the resolution there (if you haven't tried the Nvidia control panel yet).
