Display Data Channel
Communication protocols
Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast. Like modern analog VGA connectors, the DVI and DisplayPort connectors include pins for DDC, but DisplayPort only supports DDC within its optional Dual-Mode DP (DP++) feature in DVI/HDMI mode.
