DisplayPort

DisplayPort is a digital interface standard that carries video and audio from a source device to a display. It supports multiple display resolutions and refresh rates through successive revisions.

Main Link: The high-speed data channel that carries DisplayPort video, audio, and auxiliary data. Its lanes carry the packetized streams that make up a DisplayPort connection.
Video Electronics Standards Association: An international industry organization that develops standards for display and video interfaces. VESA develops and maintains the DisplayPort standard.
Active DisplayPort adapter: An adapter that electronically converts DisplayPort signaling into another video interface's signaling. It enables connections to HDMI or DVI displays when passive conversion is unsupported.
HDMI: A digital interface standard for transmitting video and audio between source devices and displays. HDMI is the most common alternative for televisions and consumer audiovisual equipment.
DisplayPort AUX channel: A bidirectional low-speed channel used for link configuration, device control, and display data exchange. It configures the main link and retrieves display capabilities before transmission.
Transition-Minimized Differential Signaling: A signaling method used by DVI and HDMI to transmit digital video over differential pairs. Unlike DisplayPort's packet-based link, older HDMI and DVI implementations use TMDS signaling.
DisplayPort connector: A family of physical connectors used to carry DisplayPort signals between devices. Its full-size and Mini DisplayPort forms provide distinct physical connection options.
Digital Visual Interface: A digital video interface standard developed before HDMI and DisplayPort. DVI lacks DisplayPort's modern audio and multi-stream features in its common forms.
Display Data Channel: A communication path that lets a computer read display capabilities and control a monitor. DisplayPort uses this channel over its AUX connection for display identification and control.
Display Data Channel Command Interface: A protocol for sending monitor-control commands over a display data channel. It allows software to adjust monitor settings through a DisplayPort connection.
