A bidirectional, half-duplex auxiliary channel carries device management and device control data for the Main Link, such as VESA EDID, MCCS, and DPMS standards.

The video signal path can range from six to sixteen bits per color channel, and the audio path can have up to eight channels of 24-bit, 192 kHz uncompressed PCM audio. ĭisplayPort can be used to transmit audio and video simultaneously, although each can be transmitted without the other. The use of data packets also makes it extensible, meaning more features can be added over time without significant changes to the physical interface. Unlike legacy standards that transmit a clock signal with each output, its protocol is based on small data packets known as micro packets, which can embed the clock signal in the data stream, allowing higher resolution using fewer pins. It permits the use of internal and external display connections. 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 is backward compatible with other interfaces, such as HDMI and DVI, through the use of either active or passive adapters. ĭisplayPort was designed to replace VGA, FPD-Link, and Digital Visual Interface (DVI). It can also carry audio, USB, and other forms of data. It is primarily used to connect a video source to a display device such as a computer monitor.
