Versions


1.0 to 1.1

The first version, 1.0, was approved by VESA on 3 May 2006. Version 1.1 was ratified on 2 April 2007, and version 1.1a was ratified on 11 January 2008. DisplayPort 1.0–1.1a allow a maximum bandwidth of 10.8Gbit/s (8.64Gbit/s data rate) over a standard 4-lane main link. DisplayPort cables up to 2 meters in length are required to support the full 10.8Gbit/s bandwidth. DisplayPort 1.1 allows devices to implement alternative link layers such as

1.2

DisplayPort version 1.2 was introduced on 7 January 2010. The most significant improvement of this version is the doubling of the data rate to 17.28Gbit/s in High Bit Rate 2 (HBR2) mode, which allows increased resolutions, higher refresh rates, and greater color depth, such as at 60Hz 10bpc RGB. Other improvements include multiple independent video streams (daisy-chain connection with multiple monitors) called Multi-Stream Transport, facilities for

FreeSync was first demonstrated at CES 2014 on a Toshiba Satellite laptop by making use of the Panel-Self-Refresh (PSR) feature from the Embedded DisplayPort standard, and after a proposal from AMD, VESA later adapted the Panel-Self-Refresh feature for use in standalone displays and added it as an optional feature of the main DisplayPort standard under the name "Adaptive-Sync" in version 1.2a. As it is an optional feature, support for Adaptive-Sync is not required for a display to be DisplayPort 1.2a-compliant.


1.3

DisplayPort version 1.3 was approved on 15 September 2014. This standard increases overall transmission bandwidth to 32.4Gbit/s with the new HBR3 mode featuring 8.1Gbit/s per lane (up from 5.4Gbit/s with HBR2 in version 1.2), for a total data throughput of 25.92Gbit/s after factoring in 8b/10b encoding overhead.

On displays which do not support DSC, the maximum limits are unchanged from DisplayPort1.3 (4K 120Hz, 5K 60Hz, 8K 30Hz).


1.4a

DisplayPort version 1.4a was published in April 2018. VESA made no official press release for this version. It updated DisplayPort's DSC implementation from DSC 1.2 to 1.2a.


2.0

On 26 June 2019, VESA formally released the DisplayPort 2.0 standard. VESA stated that version 2.0 is the first major update to the DisplayPort standard since March 2016, and provides up to a ≈3× improvement in data rate (from 25.92 to 77.37Gbit/s) compared to the previous version of DisplayPort (1.4a), as well as new capabilities to address the future performance requirements of traditional displays. These include beyond 8K resolutions, higher refresh rates and high dynamic range (HDR) support at higher resolutions, improved support for multiple display configurations, as well as improved user experience with augmented/virtual reality (AR/VR) displays, including support for 4K-and-beyond VR resolutions. Products incorporating DisplayPort 2.0 are not projected by VESA to appear on the market until later in 2021. According to a roadmap published by VESA in September 2016, a new version of DisplayPort was intended to be launched in "early 2017". It would have improved the link rate from 8.1 to 10.0Gbit/s, a 23% increase. This would have increased the total bandwidth from 32.4Gbit/s to 40.0Gbit/s. However, no new version was released in 2017, likely delayed to make further improvements after the HDMI Forum announced in January 2017 that their next standard (HDMI2.1) would offer up to 48Gbit/s of bandwidth. According to a press release on 3 January 2018, "VESA is also currently engaged with its members in the development of the next DisplayPort standard generation, with plans to increase the data rate enabled by DisplayPort by two-fold and beyond. VESA plans to publish this update within the next 18 months." At CES 2019, VESA announced that the new version would support 8K @ 60Hz without compression and was expected to be released in the first half of 2019.


DP 2.0 configuration examples

With the increased bandwidth enabled by DisplayPort 2.0, VESA offers a high degree of versatility and configurations for higher display resolutions and refresh rates. In addition to the above-mentioned 8K resolution at 60Hz with HDR support, UHBR20 through USB-C as DisplayPort Alt Mode enables a variety of high-performance configurations: * Single display resolutions ** One 16K () display @ 60Hz with 10bpc (30bit/px, HDR) RGB/ 4:4:4 color (with DSC) ** One 10K () display @ 60Hz and 8bpc (24bit/px, SDR) RGB/ 4:4:4 color (uncompressed) * Dual display resolutions ** Two 8K () displays @ 120Hz and 10bpc (30bit/px, HDR) RGB/ 4:4:4 color (with DSC) ** Two 4K () displays @ 144Hz and 8bpc (24bit/px, SDR) RGB/ 4:4:4 color (uncompressed) * Triple display resolutions ** Three 10K () displays @ 60Hz and 10bpc (30bit/px, HDR) RGB/ 4:4:4 color (with DSC) ** Three 4K () displays @ 90Hz and 10bpc (30bit/px, HDR) RGB/ 4:4:4 color (uncompressed) When using only two lanes on the USB-C connector via DP Alt Mode to allow for simultaneous SuperSpeed USB data and video, DP 2.0 can enable such configurations as: * Three 4K () displays @ 144Hz and 10bpc (30bit/px, HDR) RGB/ 4:4:4 color (with DSC) * Two 4K × 4K () displays (for AR/VR headsets) @ 120Hz and 10bpc (30bit/px, HDR) RGB/ 4:4:4 color (with DSC) * Three QHD () @ 120Hz and 8bpc (24bit/px, SDR) RGB/ 4:4:4 color (uncompressed) * One 8K () display @ 30Hz and 10bpc (30bit/px, HDR) RGB/ 4:4:4 color (uncompressed)


2.1

VESA announced version 2.1 of the DisplayPort standard on 17 October 2022. This version incorporates the new DP40 and DP80 cable certifications, which test DisplayPort cables for proper operation at the UHBR10 (40Gbit/s) and UHBR20 (80Gbit/s) speeds introduced in version 2.0. Additionally, it revises some of the electrical requirements for DisplayPort devices in order to improve integration with USB4. In VESA's words:
DisplayPort 2.1 has tightened its alignment with the USB Type-C specification as well as the USB4 PHY specification to facilitate a common PHY servicing both DisplayPort and USB4. In addition, DisplayPort 2.1 has added a new DisplayPort bandwidth management feature to enable DisplayPort tunneling to coexist with other I/O data traffic more efficiently over the USB4 link.


Specifications


Main specifications


Main link

The DisplayPort ''main link'' is used for transmission of video and audio. The main link consists of a number of unidirectional serial data channels which operate concurrently, called ''lanes''. A standard DisplayPort connection has 4 lanes, though some applications of DisplayPort implement more, such as the
Thunderbolt 3 Thunderbolt is the brand name of a hardware interface for the connection of external peripherals to a computer. It has been developed by Intel, in collaboration with Apple. It was initially marketed under the name Light Peak, and first sold as ...

differential signaling Differential signalling is a method for electrically transmitting information using two complementary signals. The technique sends the same electrical signal as a differential pair of signals, each in its own conductor. The pair of conduc ...
. This is a self-clocking system, so no dedicated clock signal channel is necessary. Unlike DVI and HDMI, which vary their transmission speed to the exact rate required for the specific video format, DisplayPort only operates at a few specific speeds; any excess bits in the transmission are filled with "stuffing symbols". In DisplayPort versions 1.01.4a, the data is encoded using ANSI 8b/10b encoding prior to transmission. With this scheme, only 8 out of every 10 transmitted bits represent data; the extra bits are used for DC balancing (ensuring a roughly equal number of 1s and 0s). As a result, the rate at which data can be transmitted is only 80% of the physical bitrate. The transmission speeds are also sometimes expressed in terms of the "Link Symbol Rate", which is the rate at which these 8b/10b-encoded symbols are transmitted (i.e. the rate at which groups of 10 bits are transmitted, 8 of which represent data). The following transmission modes are defined in version 1.01.4a: * RBR (Reduced Bit Rate): 1.62Gbit/s bandwidth per lane (162MHz link symbol rate) * HBR (High Bit Rate): 2.70Gbit/s bandwidth per lane (270MHz link symbol rate) * HBR2 (High Bit Rate 2): 5.40Gbit/s bandwidth per lane (540MHz link symbol rate), introduced in DP1.2 * HBR3 (High Bit Rate 3): 8.10Gbit/s bandwidth per lane (810MHz link symbol rate), introduced in DP1.3 DisplayPort 2.0 uses 128b/132b encoding; each group of 132 transmitted bits represents 128 bits of data. This scheme has an efficiency of 96.%. In addition, a small amount of overhead is added for the link layer control packet and other miscellaneous operations, resulting in an overall efficiency of ≈96.7%.VESA DisplayPort Standard, Version 2.1. Video Electronics Standards Association (VESA). 10 October 2022. The following transmission modes are added in DP 2.0: * UHBR 10 (Ultra High Bit Rate 10): 10.0Gbit/s bandwidth per lane * UHBR 13.5 (Ultra High Bit Rate 13.5): 13.5Gbit/s bandwidth per lane * UHBR 20 (Ultra High Bit Rate 20): 20.0Gbit/s bandwidth per lane The total bandwidth of the main link in a standard 4-lane connection is the aggregate of all lanes: * RBR: 4 × 1.62Gbit/s = 6.48Gbit/s bandwidth (data rate of 5.184Gbit/s or 648MB/s with 8b/10b encoding) * HBR: 4 × 2.70Gbit/s = 10.80Gbit/s bandwidth (data rate of 8.64Gbit/s or 1.08GB/s) * HBR2: 4 × 5.40Gbit/s = 21.60Gbit/s bandwidth (data rate of 17.28Gbit/s or 2.16GB/s) * HBR3: 4 × 8.10Gbit/s = 32.40Gbit/s bandwidth (data rate of 25.92Gbit/s or 3.24GB/s) * UHBR 10: 4 × 10.0Gbit/s = 40.00Gbit/s bandwidth (data rate of 38.69Gbit/s or 4.84GB/s with 128b/132b encoding and FEC) * UHBR 13.5: 4 × 13.5Gbit/s = 54.00Gbit/s bandwidth (data rate of 52.22Gbit/s or 6.52GB/s) * UHBR 20: 4 × 20.0Gbit/s = 80.00Gbit/s bandwidth (data rate of 77.37Gbit/s or 9.69GB/s) The transmission mode used by the DisplayPort main link is negotiated by the source and sink device when a connection is made, through a process called ''Link Training''. This process determines the maximum possible speed of the connection. If the quality of the DisplayPort cable is insufficient to reliably handle HBR2 speeds for example, the DisplayPort devices will detect this and switch down to a lower mode to maintain a stable connection. The link can be re-negotiated at any time if a loss of synchronization is detected. Audio data is transmitted across the main link during the video blanking intervals (short pauses between each line and frame of video data).

Cables and connectors


Cables

All DisplayPort cables are compatible with all DisplayPort devices, regardless of the version of each device or the cable certification level.

, HDR, and DSC. DisplayPort cables differ in their transmission speed support. DisplayPort specifies seven different transmission modes (RBR, HBR, HBR2, HBR3, UHBR10, UHBR13.5, and UHBR20) which support progressively higher bandwidths. Not all DisplayPort cables are capable of all seven transmission modes. VESA offers certifications for various levels of bandwidth. These certifications are optional, and not all DisplayPort cables are certified by VESA. Cables with limited transmission speed are still compatible with all DisplayPort devices, but may place limits on the maximum resolution or refresh rate available. DisplayPort cables are not classified by "version". Although cables are commonly labeled with version numbers, with HBR2 cables advertised as "DisplayPort1.2 cables" for example, this notation is not permitted by VESA. The use of version numbers with cables can falsely imply that a DisplayPort1.4 display requires a "DisplayPort1.4 cable", or that features introduced in version 1.4 such as HDR or DSC will not function with older "DP1.2 cables". DisplayPort cables are classified only by their bandwidth certification level (RBR, HBR, HBR2, HBR3, etc.), if they have been certified at all.


Cable bandwidth and certifications

Not all DisplayPort cables are capable of functioning at the highest levels of bandwidth. Cables may be submitted to VESA for an optional certification at various bandwidth levels. VESA offers four levels of cable certification: Standard, DP8K, DP40, and DP80. These certify DisplayPort cables for proper operation at the following speeds: In April 2013, VESA published an article stating that the DisplayPort cable certification did not have distinct tiers for HBR and HBR2 bandwidth, and that any certified standard DisplayPort cable—including those certified under DisplayPort1.1—would be able to handle the 21.6Gbit/s bandwidth of HBR2 that was introduced with the DisplayPort 1.2 standard. The DisplayPort1.2 standard defines only a single specification for High Bit Rate cable assemblies, which is used for both HBR and HBR2 speeds, although the DP cable certification process is governed by the DisplayPort PHY Compliance Test Standard (CTS) and not the DisplayPort standard itself. The DP8K certification was announced by VESA in January 2018, and certifies cables for proper operation at HBR3 speeds (8.1Gbit/s per lane, 32.4Gbit/s total). In June 2019, with the release of version 2.0 of the DisplayPort Standard, VESA announced that the DP8K certification was also sufficient for the new UHBR10 transmission mode. No new certifications were announced for the UHBR13.5 and UHBR20 modes. VESA is encouraging displays to use tethered cables for these speeds, rather than releasing standalone cables onto the market. It should also be noted that the use of Display Stream Compression (DSC), introduced in DisplayPort1.4, greatly reduces the bandwidth requirements for the cable. Formats which would normally be beyond the limits of DisplayPort1.4, such as 4K (38402160) at 144Hz 8bpc RGB/ 4:4:4 (31.4Gbit/s data rate when uncompressed), can only be implemented by using DSC. This would reduce the physical bandwidth requirements by 2–3×, placing it well within the capabilities of an HBR2-rated cable. This exemplifies why DisplayPort cables are not classified by "version"; although DSC was introduced in version 1.4, this does not mean it needs a so-called "DP1.4 cable" (an HBR3-rated cable) to function. HBR3 cables are only required for applications which exceed HBR2-level bandwidth, not simply any application involving DisplayPort1.4. If DSC is used to reduce the bandwidth requirements to HBR2 levels, then an HBR2-rated cable will be sufficient. In version 2.1, VESA introduced the DP40 and DP80 cable certification tiers, which validate cables for UHBR10 and UHBR20 speeds respectively.


Cable length

The DisplayPort standard does not specify any maximum length for cables, though the DisplayPort 1.2 standard does set a minimum requirement that all cables up to 2 meters in length must support HBR2 speeds (21.6Gbit/s), and all cables of any length must support RBR speeds (6.48Gbit/s). Cables longer than 2 meters may or may not support HBR/HBR2 speeds, and cables of any length may or may not support HBR3 speeds or above.


Connectors and pin configuration

DisplayPort cables and ports may have either a "full-size" connector or a "mini" connector. These connectors differ only in physical shape—the capabilities of DisplayPort are the same regardless of which connector is used. Using a Mini DisplayPort connector does not affect performance or feature support of the connection.


Full-size DisplayPort connector

The standard DisplayPort connector (now referred to as a "full-size" connector to distinguish it from the mini connector) was the sole connector type introduced in DisplayPort1.0. It is a 20-pin single-orientation connector with a friction lock and an optional mechanical latch. The standard DisplayPort receptacle has dimensions of 16.10mm (width) × 4.76mm (height) × 8.88mm (depth). The standard DisplayPort connector pin allocation is as follows: * 12 pins for the main link – the main link consists of four

for use in their computer products. It was first announced in October 2008 for use in the new MacBooks and Cinema Display. In 2009, VESA adopted it as an official standard, and in 2010 the specification was merged into the main DisplayPort standard with the release of DisplayPort1.2. Apple freely licenses the specification to VESA. The Mini DisplayPort (mDP) connector is a 20-pin single-orientation connector with a friction lock. Unlike the full-size connector, it does not have an option for a mechanical latch. The mDP receptacle has dimensions of 7.50mm (width) × 4.60mm (height) × 4.99mm (depth). The mDP pin assignments are the same as the full-size DisplayPort connector.


DP_PWR (pin 20)

Pin 20 on the DisplayPort connector, called DP_PWR, provides 3.3V (±10%) DC power at up to 500mA (minimum power delivery of 1.5W). This power is available from all DisplayPort receptacles, on both source and display devices. DP_PWR is intended to provide power for adapters, amplified cables, and similar devices, so that a separate power cable is not necessary. Standard DisplayPort cable connections do not use the DP_PWR pin. Connecting the DP_PWR pins of two devices directly together through a cable can create a
short circuit A short circuit (sometimes abbreviated to short or s/c) is an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance. This results in an excessive current flowing through the circui ...
which can potentially damage devices, since the DP_PWR pins on two devices are unlikely to have exactly the same voltage (especially with a ±10% tolerance). For this reason, the DisplayPort1.1 and later standards specify that passive DisplayPort-to-DisplayPort cables must leave pin 20 unconnected. However, in 2013 VESA announced that after investigating reports of malfunctioning DisplayPort devices, it had discovered that a large number of non-certified vendors were manufacturing their DisplayPort cables with the DP_PWR pin connected: The stipulation that the DP_PWR wire be omitted from standard DisplayPort cables was not present in the DisplayPort1.0 standard. However, DisplayPort products (and cables) did not begin to appear on the market until 2008, long after version 1.0 had been replaced by version 1.1. The DisplayPort1.0 standard was never implemented in commercial products.


Resolution and refresh frequency limits

The tables below describe the refresh frequencies that can be achieved with each transmission mode. In general, maximum refresh frequency is determined by the transmission mode (RBR, HBR, HBR2, HBR3, UHBR 10, UHBR 13.5, or UHBR 20). These transmission modes were introduced to the DisplayPort standard as follows: * RBR and HBR were defined in the initial release of the DisplayPort standard, version 1.0 * HBR2 was introduced in version 1.2 * HBR3 was introduced in version 1.3 * UHBR 10, UHBR 13.5, and UHBR 20 were introduced in version 2.0 However, transmission mode support is not necessarily dictated by a device's claimed "DisplayPort version number". For example, older versions of the DisplayPort Marketing Guidelines allowed a device to be labeled as "DisplayPort 1.2" if it supported the MST feature, even if it didn't support the HBR2 transmission mode. Newer versions of the guidelines have removed this clause, and currently (as of the June 2018 revision) there are no guidelines on the usage of DisplayPort version numbers in products. DisplayPort "version numbers" are therefore not a reliable indication of what transmission speeds a device can support. In addition, individual devices may have their own arbitrary limitations beyond transmission speed. For example,
NVIDIA Nvidia CorporationOfficially written as NVIDIA and stylized in its logo as VIDIA with the lowercase "n" the same height as the uppercase "VIDIA"; formerly stylized as VIDIA with a large italicized lowercase "n" on products from the mid 1990s to ...
Kepler GK104 GPUs (such as the GeForce GTX 680 and 770) support "DisplayPort 1.2" with the HBR2 transmission mode, but are limited to 540Mpx/s, only of the maximum possible with HBR2. Consequently, certain devices may have limitations that differ from those listed in the following tables. To support a particular format, the source and display devices must both support the required transmission mode, and the DisplayPort cable must also be capable of handling the required bandwidth of that transmission mode. (See: Cables and connectors)


Refresh frequency limits for common resolutions

The maximum limits for the RBR and HBR modes are calculated using standard data rate calculations. For UHBR modes, the limits are based on the data efficiency calculations provided by the DisplayPort standard. All calculations assume uncompressed RGB video with CVT-RB v2 timing. Maximum limits may differ if compression (i.e. DSC) or 4:2:2 or 4:2:0 chroma subsampling are used. Display manufacturers may also use non-standard blanking intervals rather than CVT-RB v2 to achieve even higher frequencies when bandwidth is a constraint. The refresh frequencies in the below table do not represent the absolute maximum limit of each interface, but rather an estimate based on a modern standardized timing formula. The minimum blanking intervals (and therefore the exact maximum frequency that can be achieved) will depend on the display and how many secondary data packets it requires, and therefore will differ from model to model.


Refresh frequency limits for standard video

Color depth of 8bpc (24bit/px or 16.7 million colors) is assumed for all formats in these tables. This is the standard color depth used on most computer displays. Note that some operating systems refer to this as "32-bit" color depth—this is the same as 24-bit color depth. The 8 extra bits are for alpha channel information, which is only present in software. At the transmission stage, this information has already been incorporated into the primary color channels, so the actual video data transmitted across the cable only contains 24 bits per pixel.


Refresh frequency limits for HDR video

Color depth of 10bpc (30bit/px or 1.07 billion colors) is assumed for all formats in these tables. This color depth is a requirement for various common HDR standards, such as
HDR10 HDR10 Media Profile, more commonly known as HDR10, is an open high-dynamic-range video (HDR) standard announced on 27 August 2015 by the Consumer Technology Association. It is the most widespread of the HDR formats. HDR10 is not backward compat ...
. It requires 25% more bandwidth than standard 8bpc video. HDR extensions were defined in version 1.4 of the DisplayPort standard. Some displays support these HDR extensions, but may only implement HBR2 transmission mode if the extra bandwidth of HBR3 is unnecessary (for example, on 4K 60Hz HDR displays). Since there is no definition of what constitutes a "DisplayPort 1.4" device, some manufacturers may choose to label these as "DP 1.2" devices despite their support for DP 1.4 HDR extensions. As a result, DisplayPort "version numbers" should not be used as an indicator of HDR support.


Features


DisplayPort dual-mode (DP++)

DisplayPort Dual-Mode (DP++), also called Dual-Mode DisplayPort, is a standard which allows DisplayPort sources to use simple passive adapters to connect to HDMI or DVI displays. Dual-mode is an optional feature, so not all DisplayPort sources necessarily support DVI/HDMI passive adapters, though in practice nearly all devices do. Officially, the "DP++" logo should be used to indicate a DP port that supports dual-mode, but most modern devices do not use the logo. Devices which implement dual-mode will detect that a DVI or HDMI adapter is attached, and send DVI/HDMI TMDS signals instead of DisplayPort signals. The original DisplayPort Dual-Mode standard (version 1.0), used in DisplayPort1.1 devices, only supported TMDS clock speeds of up to 165MHz (4.95Gbit/s bandwidth). This is equivalent to HDMI1.2, and is sufficient for up to at 60Hz. In 2013, VESA released the Dual-Mode 1.1 standard, which added support for up to a 300MHz TMDS clock (9.00Gbit/s bandwidth), and is used in newer DisplayPort1.2 devices. This is slightly less than the 340MHz maximum of HDMI1.4, and is sufficient for up to at 120Hz, at 60Hz, or at 30Hz. Older adapters, which were only capable of the 165MHz speed, were retroactively termed "Type1" adapters, with the new 300MHz adapters being called "Type2".


Dual-mode limitations

* Limited adapter speed Although the pinout and digital signal values transmitted by the DP port are identical to a native DVI/HDMI source, the signals are transmitted at DisplayPort's native voltage (3.3V) instead of the 5V used by DVI and HDMI. As a result, dual-mode adapters must contain a level-shifter circuit which changes the voltage. The presence of this circuit places a limit on how quickly the adapter can operate, and therefore newer adapters are required for each higher speed added to the standard. * Unidirectional Although the dual-mode standard specifies a method for DisplayPort ''sources'' to output DVI/HDMI signals using simple passive adapters, there is no counterpart standard to give DisplayPort displays the ability to ''receive'' DVI/HDMI input signals through passive adapters. As a result, DisplayPort displays can only receive native DisplayPort signals; any DVI or HDMI input signals must be converted to the DisplayPort format with an active conversion device. DVI and HDMI sources cannot be connected to DisplayPort displays using passive adapters. * Single-link DVI only Since DisplayPort dual-mode operates by using the pins of the DisplayPort connector to send DVI/HDMI signals, the 20-pin DisplayPort connector can only produce a ''single-link'' DVI signal (which uses 19 pins). A ''dual-link DVI'' signal uses 25 pins, and is therefore impossible to transmit natively from a DisplayPort connector through a passive adapter. Dual-link DVI signals can only be produced by converting from native DisplayPort output signals with an active conversion device. * Unavailable on USB-C The ''DisplayPort Alternate Mode'' specification for sending DisplayPort signals over a

cable does not include support for the dual-mode protocol. As a result, DP-to-DVI and DP-to-HDMI passive adapters do not function when chained from a USB-C to DP adapter.


Multi-Stream Transport (MST)

Multi-Stream Transport is a feature first introduced in the DisplayPort1.2 standard. It allows multiple independent displays to be driven from a single DP port on the source devices by multiplexing several video streams into a single stream and sending it to a ''branch device'', which demultiplexes the signal into the original streams. Branch devices are commonly found in the form of an MST hub, which plugs into a single DP input port and provides multiple outputs, but it can also be implemented on a display internally to provide a DP output port for daisy-chaining, effectively embedding a 2-port MST hub inside the display. Theoretically, up to 63 displays can be supported, but the combined data rate requirements of all the displays cannot exceed the limits of a single DP port (17.28Gbit/s for a DP1.2 port, or 25.92Gbit/s for a DP 1.3/1.4 port). In addition, the maximum number of links between the source and any device (i.e. the maximum length of a daisy-chain) is 7, and the maximum number of physical output ports on each branch device (such as a hub) is 7. With the release of MST, standard single-display operation has been retroactively named "SST" mode (Single-Stream Transport). Daisy-chaining is a feature that must be specifically supported by each intermediary display; not all DisplayPort1.2 devices support it. Daisy-chaining requires a dedicated DisplayPort ''output'' port on the display. Standard DisplayPort ''input'' ports found on most displays cannot be used as a daisy-chain output. Only the last display in the daisy-chain does not need to support the feature specifically or have a DP output port. DisplayPort1.1 displays can also be connected to MST hubs, and can be part of a DisplayPort daisy-chain if it is the last display in the chain. The host system's software also needs to support MST for hubs or daisy-chains to work. While Microsoft Windows environments have full support for it,
Apple An apple is an edible fruit produced by an apple tree (''Malus domestica''). Apple trees are cultivated worldwide and are the most widely grown species in the genus ''Malus''. The tree originated in Central Asia, where its wild ancestor, ' ...
operating systems currently do not support MST hubs or DisplayPort daisy-chaining as of macOS 10.15 ("Catalina"). DisplayPort-to-DVI and DisplayPort-to-HDMI adapters/cables may or may not function from an MST output port; support for this depends on the specific device. MST is supported by USB Type-C DisplayPort Alternate Mode, so standard DisplayPort daisy-chains and MST hubs do function from Type-C sources with a simple Type-C to DisplayPort adapter.


High dynamic range (HDR)

Support for HDR video was introduced in DisplayPort1.4. It implements the CTA 861.3 standard for transport of static HDR metadata in EDID.

This portion of the standard is licensed separately. It also adds the ability to verify the proximity of the receiver and transmitter, a technique intended to ensure users are not bypassing the content protection system to send data out to distant, unauthorized users. DisplayPort1.1 added optional implementation of industry-standard 56-bit HDCP (

Market share

Figures from IDC show that 5.1% of commercial desktops and 2.1% of commercial notebooks released in 2009 featured DisplayPort. The main factor behind this was the phase-out of VGA, and that both Intel and AMD planned to stop building products with FPD-Link by 2013. Nearly 70% of LCD monitors sold in August 2014 in the US, UK, Germany, Japan, and China were equipped with HDMI/DisplayPort technology, up 7.5% on the year, according to Digitimes Research.

, it meets the ISO/IEC 29170 standard for "visually lossless" compression, a form of compression in which "the user cannot tell the difference between a compressed and uncompressed image". ISO 29170 more specifically defines an algorithm as visually lossless "when all the observers fail to correctly identify the reference image more than 75% of the trials". However, the standard allows for images that "exhibit particularly strong artefacts" to be disregarded or excluded from testing, such as engineered test images. Research of DSC using the ISO/IEC 29170 interleaved protocol, in which an uncompressed reference image is presented side by side with a rapidly alternating sequence of the compressed test image and uncompressed reference image, and performed with various types of images (such as people, natural and man-made scenery, text, and known challenging imagery) shows that in most images DSC satisfies the standard's criterion for visually lossless performance, although in some trials participants were able to detect the presence of compression on certain images. DSC compression works on a horizontal line of pixels encoded using groups of three consecutive pixels for native 4:4:4 and simple 4:2:2 formats, or six pixels (three compressed containers) for native 4:2:2 and 4:2:0 formats. If RGB encoding is used, it is first converted to reversible YCC. Simple conversion from 4:2:2 to 4:4:4 can add missing chroma samples by interpolating neighboring pixels. Each luma component is coded separately using three independent substreams (four substreams in native 4:2:2 mode). Prediction step is performed using one of the three modes: modified median adaptive coding (MMAP) algorithm similar to the one used by

algorithm based on delta size unit-variable length coding (DSU-VLC). Encoded pixel groups are then combined into slices of various height and width; common combinations include 100% or 25% picture width, and 8-, 32-, or 108-line height. A modified version of DSC, ''VDC-M'', is used in DSI-2. It allows for more compression at 6 bit/px at the cost of higher algorithmic complexity. DSC version 1.0 was released on 10 March 2014, but was soon deprecated by DSC version 1.1 released on 1 August 2014. The DSC standard supports up to a compression ratio (reducing the data stream to 8 bits per pixel) with constant or variable bit rate, RGB or 4:4:4, 4:2:2, or 4:2:0 color format, and color depth of 6, 8, 10, or 12 bits per color component. DSC version 1.2 was released on 27 January 2016 and is included in version 1.4 of the DisplayPort standard; DSC version 1.2a was released on 18 January 2017. The update includes native encoding of 4:2:2 and 4:2:0 formats in pixel containers, 14/16 bits per color, and minor modifications to the encoding algorithm.

''Embedded DisplayPort'' (eDP) is a display panel interface standard for portable and embedded devices. It defines the signaling interface between graphics cards and integrated displays. The various revisions of eDP are based on existing DisplayPort standards. However, version numbers between the two standards are not interchangeable. For instance, eDP version 1.4 is based on DisplayPort 1.2, while eDP version 1.4a is based on DisplayPort 1.3. In practice, embedded DisplayPort has displaced

as the predominant panel interface in modern laptops and modern smartphones. eDP 1.0 was adopted in December 2008. It included advanced power-saving features such as seamless refresh rate switching. Version 1.1 was approved in October 2009 followed by version 1.1a in November 2009. Version 1.2 was approved in May 2010 and includes DisplayPort 1.2 HBR2 data rates, 120Hz

Version 1.4 was released in February 2013; it reduces power consumption through partial-frame updates in PSR mode, regional backlight control, lower interface voltages, and additional link rates; the auxiliary channel supports multi-touch panel data to accommodate different form factors. Version 1.4a was published in February 2015; the underlying DisplayPort version was updated to 1.3 in order to support HBR3 data rates, Display Stream Compression 1.1, Segmented Panel Displays, and partial updates for Panel Self-Refresh. Version 1.4b was published in October 2015; its protocol refinements and clarifications are intended to enable adoption of eDP 1.4b in devices by mid-2016. Version 1.5 was published in October 2021; adds new features and protocols, including enhanced support for Adaptive-Sync, that provide additional power savings and improved gaming and media playback performance.


iDP

''Internal DisplayPort'' (iDP) 1.0 was approved in April 2010. The iDP standard defines an internal link between a digital TV system on a chip controller and the display panel's timing controller. It aims to replace currently used internal

lanes with a DisplayPort connection. iDP features a unique physical interface and protocols, which are not directly compatible with DisplayPort and are not applicable to external connection, however they enable very high resolution and refresh rates while providing simplicity and extensibility. iDP features a non-variable 2.7GHz clock and is nominally rated at 3.24Gbit/s per lane, with up to sixteen lanes in a ''bank'', resulting in a six-fold decrease in wiring requirements over FPD-Link for a 1080p24 signal; other data rates are also possible. iDP was built with simplicity in mind so doesn't have an AUX channel, content protection, or multiple streams; it does however have frame sequential and line interleaved stereo 3D.

''Wireless DisplayPort'' (''wDP'') enables the bandwidth and feature set of DisplayPort 1.2 for cable-free applications operating in the 60GHz radio band. It was announced in November 2010 by WiGig Alliance and VESA as a cooperative effort.


SlimPort

''SlimPort'', a brand of Analogix products, complies with ''Mobility DisplayPort'', also known as ''MyDP'', which is an industry standard for a mobile audio/video Interface, providing connectivity from mobile devices to external displays and HDTVs. SlimPort implements the transmission of video up to 4K-UltraHD and up to eight channels of audio over the

and embedded displays. The latest version 1.3 (announced on 23 September 2013) adds enhanced support for tiled display topologies; it allows better identification of multiple video streams, and reports bezel size and locations. As of December 2013, many current 4K displays use a tiled topology, but lack a standard way to report to the video source which tile is left and which is right. These early 4K displays, for manufacturing reasons, typically use two 1920×2160 panels laminated together and are currently generally treated as multiple-monitor setups. DisplayID 1.3 also allows 8K display discovery, and has applications in stereo 3D, where multiple video streams are used.

Support for DisplayPort Alternate Mode over USB-C

Currently, DisplayPort is the most widely implemented alternate mode, and is used to provide video output on devices that do not have standard-size DisplayPort or HDMI ports, such as smartphones, tablets, and laptops. A USB-C multiport adapter converts the device's native video stream to DisplayPort/HDMI/VGA, allowing it to be displayed on an external display, such as a television set or computer monitor. Examples of devices that support DisplayPort Alternate Mode over USB-C include: MacBook, Chromebook Pixel,
