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.
DisplayPort Dual-Mode (DP++), also called Dual-Mode DisplayPort, is a standard which allows DisplayPort sources to use simple passive adapters to connect to HDMI or DVI displays, and allows DisplayPort displays to use simple passive adapters to connect HDMI or DVI sources. Dual-mode is an optional feature, so not all DisplayPort sources ...
A monitor is typically connected to its host computer via DisplayPort, HDMI, USB-C, DVI, or VGA.

DSC can work in constant or variable bitrate mode. The minimum allowed bits-per-pixel (BPP) is 6 bit/px; [7]: 52 the typical BPP given on VESA's website is 8 bit/px. [8] The variable-bitrate is actually a way to temporarily disable the display link; [7]: 125 it only adds the possibility of choosing 0 bit/px. [7]: 41
