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. ^ a b Pins 13 and 14 may either be directly connected to ground or connected to ground through a pulldown device.ĭisplayPort connector A DisplayPort port (top right) near an Ethernet port and a USB portĭisplayPort ( DP) is a digital display interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA).^ a b c d e f g h This is the pinout for source-side connector, the sink-side connector pinout will have lanes 0–3 reversed in order i.e., lane 3 will be on pin 1(n) and 3(p) while lane 0 will be on pin 10(n) and 12(p).and 30/20 pins for internal connections between graphics engines and built-in flat panels.ġ.62, 2.7, 5.4, 8.1, or 20 Gbit/s data rate per lane 1, 2, or 4 lanes (effective total 5.184, 8.64, 17.28, 25.92, or 77.37 Gbit/s for 4-lane link) 2 or 720 Mbit/s (effectively 1 or 576 Mbit/s) for the auxiliary channel.
