I recently bought a Samsung 32" 720p TV with a native resolution of 1366x768 (1360x768 in Windows). I'm using HDMI with a DVI to HDMI adapter. I can see the options for flat panel scaling in the nVidia control panel. I don't want the panel to scale to widescreen with 1024x768 games. I want it centered, so I select "Do not scale" and hit apply. After I click on Yes it goes back to "Use displays built in scaling". Any option I select it goes back to "Use displays built in scaling". What's wrong here?
