I'm trying to set this monitor to a widescreen resolution... but it won't let me. All the resolutions I can pick are standard definitions; even the monitor's native resolution (1680x1050) is not selectable. I think this has something to do with the drivers; I could not install the driver from the CD because it apparently needs Vista, but from the specs of others with this monitor, it should work fine with Windows XP. Even downloading the driver straight from the website and trying to manually install it doesn't work. Can anyone help me?
