I am trying to use a Samsung 32 inch HDTV (model UN321eh4000f) as a monitor. I have Windows 7 64-bit, and my components are fully capable of running a 64 bit system. However, when I enter the control panel for my GPU (Geforce GTX 670), I am unable to change the color depth to 64-bit. My only 2 options are 16-bit and 32-bit. Is this due to my HDTV not being able to handle 64-bit color depth?
