One of my computers is using an old video card that doesn't have drivers for the OS. So, in the monitor options, I can't select a refresh rate faster than 75hz (drop down menu doesn't go any higher than this), since the adapter isn't recognized. Is there a way to manually input the refresh rate to 85hz? Maybe a registry hack? I'd like to avoid going out and buying another PCI video card b/c I don't use that computer for anything but word processing, and internet surfing. Thanks for any help in advance.
