What is DisplayPort?

DisplayPort is a digital display interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA). It is primarily used to connect a video source to a display device such as a computer monitor. It can also carry audio, USB, and other forms of data.

DisplayPort was designed to replace VGA, FPD-Link, and Digital Visual Interface (DVI). It is backward compatible with other interfaces, such as HDMI and DVI, through the use of either active or passive adapters. It is the first display interface to rely on packetized data transmission, a form of digital communication found in technologies such as Ethernet, USB, and PCI Express. It permits the use of internal and external display connections.

DisplayPort Versions

DisplayPort has evolved over the years, with new versions offering higher bandwidth and support for new features. The latest version, DisplayPort 2.1, was released in 2022 and supports resolutions up to 16K at 60Hz with HDR.
