DisplayPort (DP) is an interface for connecting digital video managed by VESA (Video Electronics Standards Association) and designed as a replacement for the DVI standard in computer equipment. It is similar to the standard HDMI specification, both supporting audio and video, but unlike HDMI, DisplayPort is more of a computer interface than a home theater interface. DisplayPort enables high display performance, robustness and versatility, as well as a high degree of integration with systems, and greater interoperability between different types of devices.
DisplayPort uses a small plug and a thin cable that extends up to 15 meters (50 feet). First deployed in 2008, DisplayPort gained traction in personal computers, but Mini DisplayPort and its Thunderbolt variation have been the main display interfaces on Macs.
Unlike other monitor interfaces, DisplayPort transmits packets, each of which contains its own clock signal for synchronization. The packet architecture allows DisplayPort to be upgraded much more easily than an interface where each physical pin (pin) is dedicated to some purpose. In addition, DisplayPort allows you to connect thinner displays, because its direct drive interface eliminates circuitry that would otherwise be in the monitor taking up more physical space.
DisplayPort supports multiple independent data streams and can drive up to six daisy-chained monitors. It also includes an auxiliary channel for device control and management to allow transfer of video, along with USB data.
