The specifications for 8 and 10 bit color depth is 8 bit is 16.7 million colors whereas 10 bit is 1.07 billion. Just as the case with HDMI, for 10bit 1.07 billion colors to be shown on your monitor, all devices must support it. That means the source, whether it be a computer video card, a game console, set top box, DVR or Satellite box as well as the cable and the monitor/TV must ALL support it for 10 bit color depth to function. Please keep this in mind when selecting your components.
