![]() ![]() This allows for higher resolution using fewer pins. It permits the use of internal and external display connections, and unlike legacy standards that transmit a clock signal with each output, the DisplayPort protocol is based on small data packets known as micro packets, which can embed the clock signal within the data stream. The interface is backward compatible with other interfaces, such as HDMI and DVI, through the use of either active or passive adapters.Contents1 Overview2 Versions2.1 1.0 to 1.12.2 1.22.2.1 1.2a2.3 1.32.4 1.42.4.1 1.4a2.5 Next version3 Specifications3.1 Main specifications3.1.1 Main link3.1.2 Auxiliary channel4 Cables and connectors4.1 Cables4.1.1 Compatibility and feature support4.1.2 Cable bandwidth and certifications4.1.3 Cable length4.2 Connectors and pin configuration4.2.1 Full-size DisplayPort connector4.2.2 Mini DisplayPort connector4.2.3 DP_PWR Pin5 Resolution and refresh frequency limits5.1 Refresh frequency limits for standard video5.2 Refresh frequency limits for HDR video6 Features6.1 DisplayPort Dual-Mode (DP )6.1.1 Dual-Mode limitations6.2 Multi-Stream Transport (MST)6.3 High Dynamic Range (HDR)6.4 Content protection7 Cost8 Advantages over DVI, VGA and FPD-Link9 Comparison with HDMI10 Market share11 Companion standards11.1 Mini DisplayPort11.2 Micro DisplayPort11.3 DDM11.4 Display Stream Compression11.5 eDP11.6 iDP11.7 PDMI11.8 wDP11.9 SlimPort11.10 DisplayID11.11 DockPort11.12 USB-C12 Products12.1 Support for DisplayPort Alternate Mode over USB-C13 Participating companies14 See also15 Notes16 References17 External linksOverviewDisplayPort 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. The interface is primarily used to connect a video source to a display device such as a computer monitor, and it can also carry audio, USB, and other forms of data.DisplayPort was designed to replace VGA, DVI, and FPD-Link. ![]() DisplayPort connector A Mini DisplayPort receptacle (center)DisplayPort (DP) is a digital display interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA). current0.5 ADataData signalYesBitrate1.62, 2.7, 5.4, or 8.1 Gbit/s data rate per lane 1, 2, or 4 lanes (effective total 5.184, 8.64, 17.28, or 25.92 Gbit/s for 4-lane link) 1 Mbit/s or 720 Mbit/s for the auxiliary channel.ProtocolMini-packetPin outExternal connector (source-side) on PCBPin 1ML_Lane 0 (p)Lane 0 (positive)Pin 2GNDGroundPin 3ML_Lane 0 (n)Lane 0 (negative)Pin 4ML_Lane 1 (p)Lane 1 (positive)Pin 5GNDGroundPin 6ML_Lane 1 (n)Lane 1 (negative)Pin 7ML_Lane 2 (p)Lane 2 (positive)Pin 8GNDGroundPin 9ML_Lane 2 (n)Lane 2 (negative)Pin 10ML_Lane 3 (p)Lane 3 (positive)Pin 11GNDGroundPin 12ML_Lane 3 (n)Lane 3 (negative)Pin 13CONFIG1Connected to groundPin 14CONFIG2Connected to groundPin 15AUX CH (p)Auxiliary channel (positive)Pin 16GNDGroundPin 17AUX CH (n)Auxiliary channel (negative)Pin 18Hot plugHot plug detectPin 19ReturnReturn for powerPin 20DP_PWRPower for connector (3.3 V 500 mA)^ 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).^ a b Pins 13 and 14 may either be directly connected to ground or connected to ground through a pulldown device. and 30/20 pins for internal connections between graphics engines and built-in flat panels.ElectricalSignal 3.3 VMax.
