Line 3: The '''Display Data Channel''', or '''DDC''', is a collection of [[Protocol (computing)\|protocols]] for digital communication between a [[computer display]] and a [[Video card\|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 ([[DisplayPort#DisplayPort ~~dual~~Dual-~~mode~~Mode (DP++)\|DP++]]) feature in DVI/HDMI mode. The standard was created by the [[Video Electronics Standards Association]] (VESA).
