10-bit color, aka "Deep Color" is a scheme where 10 bits are used for each color channel. This makes for a 30 bit RGB implementation.

IE: red: 10 bits green: 10 bits blue: 10 bits total: 30 bits

Radeon 6000 series cards DO support deep color over HDMI, but HDMI also limits the output resolution to 1920x1200, which is not optimal. I want to know if Deep color is possible over display port with the HD6xxx series graphics cards.

From what I can tell 10bits per channel is only available with the AMD FireGL cards. This is very likely to be a marketing decision to sell more high end (read expensive) video cards.

This is not strictly true, as the 6970 supports deep color over HDMI. (though at a low resolution...) Im not willing to shell out for the FireGl cards =/ – aCuria Mar 19 '11 at 16:54
