You mean the "deep color" options that don't exist in any video source currently in existence or in the pipeline? Again, I haven't tried it, but I wouldn't rule out being able to pass deep color through the 990's DVI switching - after all, HDMI v1.3 is still built on DVI, it uses no additional video conductors to carry a deep color signal, and therefore the only hold-up would be bandwidth through the switch.
