Display Port Pinouts

Display Port is a digital display interface developed by the Video Electronics Standards Association (VESA). The interface is primarily used to connect a video source to a display device such as a computer monitor, though it can also be used to carry audio, USB, and other forms of data.

Description and Details of Display Port

Display Port can be used to transmit audio and video simultaneously, but each one is optional and can be transmitted without the other. The video signal path can have 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 or can encapsulate compressed audio formats in the audio stream. A bi-directional, half-duplex auxiliary channel carries device management and device control data for the Main Link, such as VESA EDID, MCCS, and DPMS standards. In addition, the interface is capable of carrying bi-directional USB signals.

The Display Port LVDS signal protocol is not compatible with DVI or HDMI. However, Dual-mode DisplayPorts are designed to transmit a single-link DVI or HDMI 1.2/1.4 TMDS protocol across the interface through the use of an external passive adapter that selects the desired signal and converts it from 3.3 volts to 5 volts. Analog VGA and dual-link DVI require powered active adapters to convert the protocol and signal levels and do not rely on Dual-Mode. VGA adapters are powered by the Display Port connector, while dual-link DVI adapters may rely on an external power source (see Dual-mode).

Display port-cable

The Display Port connector can have one, two, or four differential data pairs (lanes) in a Main Link, each with a raw bit rate of 1.62, 2.7, 5.4, or 8.1 Gbit/s per lane with self-clock running at 162, 270, 540, or 810 MHz. The effective data rates after decoding are 1.296, 2.16, 4.32, or 6.48 Gbit/s per lane (or 80% of the total), since data is 8b/10b encoded so each eight bits of information are encoded with a ten-bit symbol.

VESA designed it to replace VGA, DVI, and FPD-Link. Display Port is backward compatible with VGA and DVI through the use of adapters. (Click to enlarge Picture)
