I read on the nVidia driver README:
"Some devices connected via analog VGA, DisplayPort, and HDMI can display the full 10 bit range of colors. Devices connected via DVI, as well as laptop internal panels connected via LVDS, will be dithered to 8 or 6 bits per pixel." Based on that statement I was hoping there was a chance for HDMI to display 10bit per color. However, I can't seem to find a Quadro card that has HDMI. Some have DisplayPort. Any idea if these are MultiMode DisplayPort, and can send the right signal when a DisplayPort to HDMI dongle is attached? (This is assuming the display can do HDMI deep color).
