DisplayPort

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 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. although alternative implementations are not standardized. It also includes HDCP in addition to DisplayPort Content Protection (DPCP). The DisplayPort1.1a standard can be downloaded free of charge from the VESA website. 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 (MST), facilities for stereoscopic 3D, increased AUX channel bandwidth (from 1Mbit/s to 720Mbit/s), more color spaces including xvYCC, scRGB, and Adobe RGB 1998, and Global Time Code (GTC) for sub 1μs audio/video synchronisation. Also Apple Inc.'s Mini DisplayPort connector, which is much smaller and designed for laptop computers and other small devices, is compatible with the new standard. 1.2a DisplayPort version 1.2a was released in January 2013 and may optionally include VESA's Adaptive Sync. AMD's FreeSync uses the DisplayPort Adaptive-Sync feature for operation. 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. This bandwidth is enough for a 4K UHD display () at 120Hz with 24bit/px RGB color, a 5K display () at 60Hz with 30bit/px RGB color, or an 8K UHD display () at 30Hz with 24bit/px RGB color. Using Multi-Stream Transport (MST), a DisplayPort port can drive two 4K UHD () displays at 60Hz, or up to four WQXGA () displays at 60Hz with 24bit/px RGB color. The new standard includes mandatory Dual-mode for DVI and HDMI adapters, implementing the HDMI2.0 standard and HDCP2.2 content protection. The Thunderbolt 3 connection standard was originally to include DisplayPort1.3 capability, but the final release ended up with only version 1.2 for Intel 6000 Series Thunderbolt 3 Controllers. Later Intel 7000 Series Thunderbolt 3 controllers support DisplayPort1.4 capability including HDR. The VESA's Adaptive Sync feature in DisplayPort version 1.3 remains an optional part of the specification. 1.4 DisplayPort version 1.4 was published 1 March 2016. No new transmission modes are defined, so HBR3 (32.4Gbit/s) as introduced in version 1.3 still remains as the highest available mode. DisplayPort1.4 adds support for Display Stream Compression 1.2 (DSC), Forward Error Correction, HDR10 metadata defined in CTA-861.3, including static and dynamic metadata and the Rec. 2020 color space, for HDMI interoperability, and extends the maximum number of inline audio channels to 32. 1.4a DisplayPort version 1.4a was published in April 2018. VESA made no official press release for this version. It updated DisplayPort's Display Stream Compression 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. 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, DP 2.0 (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 tunnelling to coexist with other data traffic more efficiently over the USB4 link. 2.1a VESA announced version 2.1a of the DisplayPort standard on 8 January 2024. This version replaces the DP40 cable certification with the new DP54 certification, which tests DisplayPort cables for proper operation at the UHBR13.5 (54Gbit/s) speed introduced in version 2.0. 2.1b VESA announced version 2.1b of the DisplayPort standard on 6 January 2025. It has been released in Spring 2025. == Specifications ==

Main 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 interface which implements up to 8 lanes of DisplayPort. In a standard DisplayPort connection, each lane has a dedicated set of twisted-pair wires, and transmits data across it using differential signaling. This is a self-clocking system, so no dedicated clock signal channel is necessary. 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%. 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 (the device accepting the signal) 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). Auxiliary channel The DisplayPort AUX channel is a half-duplex data channel used for miscellaneous additional data beyond video and audio, such as EDID (I2C) or CEC commands. This bidirectional data channel is required, since the video lane signals are unidirectional (simplex) from source to display. AUX signals are transmitted across a dedicated set of twisted-pair wires. DisplayPort1.0 specified Manchester encoding with a 2MBd signal rate (1Mbit/s data rate). Version 1.2 of the DisplayPort standard introduced a second transmission mode called FAUX (Fast AUX), which operated at 720Mbit/s with 8b/10b encoding (576Mbit/s data rate), but it was deprecated in version 1.3. == Cables and connectors ==

Cables Compatibility and feature support All DisplayPort cables are compatible with all DisplayPort devices, regardless of the version of each device or the cable certification level. All features of DisplayPort will function across any DisplayPort cable. DisplayPort does not have multiple cable designs; all DP cables have the same basic layout and wiring, and will support any feature including audio, daisy-chaining, G-Sync/FreeSync, 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. 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. The mDP pin assignments are the same as the full-size DisplayPort connector. For this reason, the DisplayPort1.1 and later standards specify that passive DisplayPort-to-DisplayPort cables must leave pin 20 unconnected. == 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, UHBR10, UHBR13.5, or UHBR20). 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 • UHBR10, UHBR13.5, and UHBR20 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 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. 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, and allows DisplayPort displays to use simple passive adapters to connect HDMI or DVI sources. 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 speedAlthough the pinout and digital signal values transmitted by the DP port are identical to a native DVI/HDMI TMDS source, the transmission lines on a DisplayPort source are AC-coupled (a series capacitor isolates the line from passing DC voltages) while DVI and HDMI TMDS are DC-coupled. As a result, dual-mode adapters must contain a level-shifting circuit which couples the signal lines to a DC source. • Single-link DVI onlySince 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-CThe DisplayPort Alternate Mode specification for sending DisplayPort signals over a USB-C 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, 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. Content protection DisplayPort1.0 includes optional DPCP (DisplayPort Content Protection) from Philips, which uses 128-bit AES encryption. It also features full authentication and session key establishment. Each encryption session is independent, and it has an independent revocation system. 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 (High-bandwidth Digital Content Protection) revision 1.3, which requires separate licensing from the Digital Content Protection LLC. DisplayPort1.3 added support for HDCP2.2, which is also used by HDMI2.0. == Cost ==

VESA, the creators of the DisplayPort standard, state that the standard is royalty-free to implement. However, in March 2015, MPEG LA issued a press release stating that a royalty rate of $0.20 per unit applies to DisplayPort products manufactured or sold in countries that are covered by one or more of the patents in the MPEG LA license pool, which includes patents from Hitachi Maxell, Philips, Lattice Semiconductor, Rambus, and Sony. In response, VESA updated its DisplayPort FAQ page in November 2015 with the following statement: By September 2025, that statement had been removed from the official FAQ. While VESA does not charge any per-device royalty fees, VESA requires membership for access to said standards. The minimum cost is presently $5,000 (or $10,000 depending on Annual Corporate Sales Revenue) annually. == Comparison with HDMI ==

Although DisplayPort has much of the same functionality as HDMI, it is a complementary connection used in different scenarios. A dual-mode DisplayPort port can emit an HDMI signal via a passive adapter. Licensing As of 2008, HDMI Licensing, LLC charged an annual fee of US$10,000 to each high-volume manufacturer, plus a per-unit royalty of US$0.04–0.15. As of 2025, DisplayPort remains royalty-free; VESA charges no per-device or per-port fees, requiring only membership to access the specification. Some third-party patent pools have previously claimed potential royalties for certain DisplayPort-related patents, but VESA continues to state that the standard itself is provided on a royalty-free basis. Bandwidth DisplayPort 1.2 has more bandwidth at 21.6Gbit/s (17.28Gbit/s plus overhead) as opposed to HDMI 2.0's 18Gbit/s (14.4Gbit/s plus overhead). DisplayPort 1.3 increased the bandwidth to 32.4Gbit/s (25.92Gbit/s plus overhead). HDMI 2.1 matched that by increasing the bandwidth up to 48Gbit/s (42.67Gbit/s plus overhead), adding an additional TMDS link in place of clock lane. In 2019, DisplayPort 2.0 once again achieved the bandwidth superiority of 80.0Gbit/s. DisplayPort can also share bandwidth through the use of the Multi-Stream Transport (MST), which enables a single DP port to carry signals of several devices, to be demultiplexed at a branch hub. Forked connectivity HDMI has supported Consumer Electronics Control (CEC) commands since the first version. The CEC bus allows connecting multiple sources to a single display, and controlling any of these devices from any remote. DisplayPort 1.3 added the possibility of transmitting CEC commands over the AUX channel. On the other hand, DisplayPort supports connecting multiple displays to one DP port via the Multi-Stream Transport (MST) feature, allowing a single computer to have multiple displays. These differences reflects the origins the two standards, and the priorities of their authors. HDMI originates from consumer electronics companies, whereas DisplayPort is owned by VESA, which started as an organization for computer standards. Other areas HDMI relies on the Vendor-Specific Block structure for features such as additional color spaces. DisplayPort uses the CEA EDID extensions. Both HDMI and DisplayPort have published specification for transmitting their signal over the USB-C connector (see ). == 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. IHS Markit, an analytics firm, forecast that DisplayPort would surpass HDMI in 2019. == Companion standards ==

Mini DisplayPort Mini DisplayPort (mDP) is a standard announced by Apple in the fourth quarter of 2008. Shortly after announcing Mini DisplayPort, Apple announced that it would license the connector technology with no fee. The following year, in early 2009, VESA announced that Mini DisplayPort would be included in the upcoming DisplayPort 1.2 specification. On 24 February 2011, Apple and Intel announced Thunderbolt, a successor to Mini DisplayPort which adds support for PCI Express data connections while maintaining backwards compatibility with Mini DisplayPort based peripherals. Micro DisplayPort Micro DisplayPort would have targeted systems that need ultra-compact connectors, such as phones, tablets and ultra-portable notebook computers. This standard would have been physically smaller than the currently available Mini DisplayPort connectors. The standard was expected to be released by Q2 2014. DDM Direct Drive Monitor (DDM) 1.0 standard was approved in December 2008. It allows for controller-less monitors where the display panel is directly driven by the DisplayPort signal, although the available resolutions and color depth are limited to two-lane operation. Display Stream Compression Display Stream Compression (DSC) is a VESA-developed video compression algorithm designed to enable increased display resolutions and frame rates over existing physical interfaces, and make devices smaller and lighter, with longer battery life. eDP 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. Unlike standard DisplayPort, the Embedded DisplayPort lacks backward compatibility. 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 sequential color monitors, and a new display panel control protocol that works through the AUX channel. PSR mode allows the GPU to enter a power saving state in between frame updates by including framebuffer memory in the display panel controller. 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) is a standard that defines an internal link between a digital TV system on a chip controller and the display panel's timing controller. Version 1.0 was approved in April 2010. It aims to replace currently used internal FPD-Link 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. 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 micro-USB connector to an external converter accessory or display device. SlimPort products support seamless connectivity to DisplayPort, HDMI and VGA displays. The MyDP standard was released in June 2012, and the first product to use SlimPort was Google's Nexus 4 smartphone. Some LG smartphones in LG G series also adopted SlimPort. SlimPort is an alternative to Mobile High-Definition Link (MHL). DisplayID DisplayID is designed to replace the E-EDID standard. DisplayID features variable-length structures which encompass all existing EDID extensions as well as new extensions for 3D displays 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. DockPort DockPort, formerly known as Lightning Bolt, is an extension to DisplayPort to include USB 3.0 data as well as power for charging portable devices from attached external displays. Originally developed by AMD and Texas Instruments, it has been announced as a VESA specification in 2014. USB-C On 22 September 2014, VESA published the DisplayPort Alternate Mode on USB Type-C Connector Standard, a specification on how to send DisplayPort signals over the newly released USB-C connector. One, two or all four of the differential pairs that USB uses for the SuperSpeed bus can be configured dynamically to be used for DisplayPort lanes. In the first two cases, the connector still can carry a full SuperSpeed signal; in the latter case, at least a non-SuperSpeed signal is available. The DisplayPort AUX channel is also supported over the two sideband signals over the same connection; furthermore, USB Power Delivery according to the newly expanded USB-PD 2.0 specification is possible at the same time. This makes the Type-C connector a strict superset of the use cases envisioned for DockPort, SlimPort, and Mini and Micro DisplayPort. However, DisplayPort Dual-Mode (DP++) is not supported under USB-C alternate mode. VirtualLink VirtualLink was a proposal to allow the power, video, and data required to drive virtual reality headsets to be delivered over a single USB-C cable. The proposal was abandoned in September 2020. == Products ==

DisplayPort connector Since DisplayPort's introduction in 2006, it has gained popularity within the computer industry and is featured on many graphics cards, displays, and notebook computers. Dell was the first company to introduce a consumer product with a DisplayPort connector, the Dell UltraSharp 3008WFP, which was released in January 2008. Soon after, AMD and Nvidia released products to support the technology. AMD included support in the Radeon HD 3000 series of graphics cards, and Nvidia first introduced support in the GeForce 9 series starting with the GeForce 9600 GT. Later in 2008, Apple introduced several products featuring a Mini DisplayPort. The new connectorproprietary at the timeeventually became part of the DisplayPort standard, however Apple reserves the right to void the license should the licensee "commence an action for patent infringement against Apple". In 2009, AMD followed suit with their Radeon HD 5000 series of graphics cards, which featured the Mini DisplayPort on the Eyefinity versions in the series. Nvidia launched a graphics card with 8 Mini DisplayPort outputs on 4 November 2015, called the NVS 810, which was intended for digital signage. Nvidia revealed the GeForce GTX 1080, the world's first graphics card with DisplayPort 1.4 support on 6 May 2016. AMD followed with the Radeon RX 480 to support DisplayPort 1.3/1.4 on 29 June 2016. The Radeon RX 400 series will support DisplayPort 1.3 HBR and HDR10, dropping the DVI connector(s) in the reference board design. In February 2017, VESA and Qualcomm announced that DisplayPort Alt Mode video transport will be integrated into the Snapdragon 835 mobile chipset, which powers smartphones, VR/AR head-mounted displays, IP cameras, tablets and mobile PCs. Support for DisplayPort Alternate Mode over USB-C Examples of devices that support DisplayPort Alternate Mode over USB-C include: MacBook, Chromebook Pixel, Surface Book 2, Samsung Galaxy Tab S4, iPad Pro (3rd generation), iPhone 15/15 Pro, HTC 10/U Ultra/U11/U12+, Huawei Mate 10/20/30, LG V20/V30/V40*/V50, OnePlus 7 and newer, ROG Phone, Samsung Galaxy S8 and newer, Nintendo Switch, Sony Xperia 1/5 etc. == Participating companies ==
