At present, Deep Color is rarely employed for actual video display outside high-end workstations and other specialized markets. Deep color is supported in digital cameras, scanners and printers to reduce aliasing and banding artifacts during internal image processing prior to final storage and output. Most analog displays can produce deep color merely by connecting them to a display adapter that outputs it, but digital displays must be designed for deep color from the beginning in order to produce it.

Industry Support

The HDMI 1.3 specification supports Deep Color bit depths. It defines bit depths for Deep Color as 30 bits (1.073 billion colors), 36 bits (68.71 billion colors), and 48 bits (281.5 trillion colors).^[1]

At WinHEC, 2008 Microsoft announced that color depths of 30-bit and 48-bit would be supported in Windows 7, along with the wide color gamut scRGB (which can be converted and output as xvYCC).^[2][3]
