Could you shed a little more light on the ATI card used for the demo? Is the card from ATI's consumer Radeon lineup or their professional FireGL line? What interconnect was used between the video card and monitor (DisplayPort, DVI, HDMI?) Are you aware of any Nvidia cards that support 10-bit color output? Is 10-bit color supported in Windows Vista (were they running vista for this demo?) and/or by the ATI drivers so that, assuming I have a 10-bit capable video card, display, and am using the proper interconnect, do I now get a 30-bit color option in Catalyst Control Center? Sorry for the bombardment of questions! I've recently been researching this exact topic but am still unclear on exactly what is required to get 10-bit color out of Vista (or if it is even possible).
