DisplayPort (DP) is a digital interface used to connect a video source, such as a computer, to a display device like a monitor. Developed by the Video Electronics Standards Association (VESA), it can also carry digital audio, USB, and other types of data over a single cable.[1][2]
Introduced in the 2000s, DisplayPort was designed to replace older standards like VGA, DVI, and FPD-Link. While not directly compatible with these formats, adapters are available for connecting to HDMI, DVI, VGA, and other interfaces.[3]
Unlike older interfaces, DisplayPort uses packet-based transmission, similar to how data is sent over USB or Ethernet. The design enables support for high resolutions and adding new features without changing the connector.[4][5]
DisplayPort includes an auxiliary data channel used for device control and automatic configuration between source and display devices. It supports standards such as Display Data Channel (DDC), Extended Display Identification Data (EDID), Monitor Control Command Set (MCCS), and VESA Display Power Management Signaling (DPMS). Some implementations also support Consumer Electronics Control (CEC), which allows devices to send commands to each other and be operated using a single remote control.
