*cough*DVI is limited to this 24-bit color depth. Early HDMI versions are also limited to this 24-bit color, but the newer 1.3 version allows colors depths of 30, 36 and even 48-bit color depths. This greatly increases the overall quality of the color that can be displayed, but both the graphics adapter and monitor must support the newer HDMI version 1.3.
