DisplayPort 2.0 allows up to 3X improve in video bandwidth performance (max payload of 77.37 Gbps); new built-in features allow improved consumer expertise, larger flexibility and improved power efficiency
SAN JOSE, Calif. – June 26, 2019 – The Video Electronics Standards Affiliation (VESA®) at this time announced that it has launched version 2.0 of the DisplayPort™ (DP) audio/video normal. DP 2.0 is the primary major replace to the DisplayPort normal since March 2016, and offers up to a 3X improve in knowledge bandwidth efficiency compared to the earlier version of DisplayPort (DP 1.4a), in addition to new capabilities to deal with the longer term efficiency requirements of traditional displays. These embrace past 8K resolutions, larger refresh rates and excessive dynamic vary (HDR) help at greater resolutions, improved help for a number of display configurations, as well as improved consumer expertise with augmented/digital actuality (AR/VR) displays, including help for 4K-and-beyond VR resolutions.
Some great benefits of DP 2.0 are enjoyed throughout each the native DP connector as well as the USB Sort-C connector, which carries the DP audio/video signal by means of DisplayPort Alt Mode. DP 2.0 is backward suitable with earlier versions of DisplayPort and incorporates all the key features of DP 1.4a, together with help for visually lossless Show Stream Compression (DSC) with Forward Error Correction (FEC), HDR metadata transport, and different superior features. The increased video bandwidth efficiency of DP 2.0 carried over the USB-C connector allows simultaneous higher-speed USB knowledge transfer without compromising show efficiency. DP 2.0 leverages the Thunderbolt™ 3 physical interface (PHY) layer whereas maintaining the pliability of DP protocol with a view to increase the info bandwidth and promote convergence throughout industry-leading IO standards.
As well as, the new knowledge charges of DP 2.0 come with a display stream knowledge mapping protocol widespread to both single-stream transport and multi-stream transport. This widespread mapping additional facilitates multi-stream transport help of DP 2.0 units for a single DP port on the source gadget to drive multiple shows either by way of a docking station or daisy-chainable shows. First products incorporating DP 2.0 are projected to seem available on the market by late 2020.
“DP 2.0 offers differentiated end-to-end user experiences, across a multitude of market segments, such as productivity and gaming, as well as wider end-to-end interoperability with various connectivity options. It sets a new paradigm for display interface specifications by providing scalability from power-efficient small form-factor displays, to high-resolution and high-refresh-rate large form-factor displays,” stated Syed Athar Hussain, VESA Board Vice Chairman and Show Area Senior Fellow, AMD.
“Intel’s contribution of the Thunderbolt™ PHY layer specification to VESA for use in DP 2.0 is a significant milestone making today’s simplest and most versatile port also the highest performing for display,” stated Jason Ziller, Basic Supervisor, Shopper Connectivity Division at Intel. “By collaborating with VESA, we’re enabling common building block technologies to come together across a wide range of devices and increasing compatibility to deliver better experiences to consumers.”
Higher-resolution Demands Mandate New Developments in Display Interfaces
Business efforts are underway to push video broadcasting beyond 4K/Extremely HD resolutions, whereas 8K televisions and PC screens are already starting to hit the market. For instance, the Japan Broadcasting Company (NHK) has announced plans to broadcast the 2020 Summer time Olympics in 8K, and has already begun to broadcast 8K content to viewers.
At the similar time, gaming platforms are pushing the envelope on immersive gameplay, driving demand for greater resolutions and video body rates across PC, laptop computer, and cellular platforms, including sensible telephones and VR headsets. Further developments in display interfaces are wanted to deal with these developments.
Tripling Knowledge Bandwidth Efficiency
The earlier model of DisplayPort, v1.4a, offered a maximum link bandwidth of 32.four Gbps, with each of the 4 lanes operating at a hyperlink price of 8.1 Gbps/lane. With 8b/10b channel coding, that equates to a maximum payload of 25.92 Gbps. DP 2.0 will increase the maximum hyperlink price to as much as 20 Gbps/lane and options more environment friendly 128b/132b channel coding, delivering a maximum payload of 77.37 Gbps – up to a three-fold improve compared to DP 1.4a. Because of this DP 2.0 is the primary commonplace to help 8K decision (7680 x 4320) at 60 Hz refresh fee with full-color four:4:4 decision, including with 30 bits per pixel (bpp) for HDR-10 help.
Maximizing Positive aspects on USB-C connector
The efficiency will increase enabled by DP 2.0 are by means of each native DP connectors and the USB-C connector by way of DP Alt Mode. USB-C permits a single connector for USB knowledge, video knowledge and energy. If simultaneous help of SuperSpeed USB knowledge and video is required, the significantly increased knowledge charges enabled by DP 2.0 give customers the power to have energy and SuperSpeed USB knowledge concurrently super-high-resolution video.
DP 2.0 Configuration Examples
With the elevated bandwidth enabled by DP 2.0, VESA presents a high diploma of versatility and configurations for larger display resolutions and refresh charges. Along with the above-mentioned 8K decision at 60 Hz with HDR help, DP 2.0 across the native DP connector or by means of USB-C as DisplayPort Alt Mode allows quite a lot of high-performance configurations:
Single display resolutions
- One 16Okay (15360×8460) display @60Hz and 30 bpp 4:4:4 HDR (with DSC)
- One 10Okay (10240×4320) display @60Hz and 24 bpp four:four:four (no compression)
Dual show resolutions
- Two 8K (7680×4320) shows @120Hz and 30 bpp 4:4:four HDR (with DSC)
- Two 4K (3840×2160) shows @144Hz and 24 bpp 4:4:four (no compression)
Triple display resolutions
- Three 10Okay (10240×4320) displays @60Hz and 30 bpp 4:four:4 HDR (with DSC)
- Three 4K (3840×2160) displays @90Hz and 30 bpp four:4:four HDR (no compression)
When utilizing solely two lanes on the USB-C connector by way of DP Alt Mode to allow for simultaneous SuperSpeed USB knowledge and video, DP 2.0 can allow such configurations as:
- Three 4K (3840×2160) shows @144Hz and 30 bpp four:four:4 HDR (with DSC)
- Two 4Kx4K (4096×4096) displays (for AR/VR headsets) @120Hz and 30 bpp four:4:4 HDR (with DSC)
- Three QHD (2560×1440) @120Hz and 24 bpp 4:four:4 (no compression)
- One 8K (7680×4320) display @30Hz and 30 bpp 4:four:four HDR (no compression)
“Being an open standards body comprising more than 280 member companies across the electronics value chain gives VESA a unique vantage point to anticipate the needs of the display market several years out and add new capabilities to our standards ahead of demand,” said Alan Kobayashi, VESA Board Chair and VESA DisplayPort Process Group Chair. “DP 2.0 represents one of our most significant milestones in the history of DisplayPort, and is the culmination of several years’ effort and major enhancements to this ubiquitous standard. Like the previous versions of DisplayPort that helped pave the way for major inflection points in video technology such as UHD, 4K, 5K, video over USB-C and HDR, DP 2.0 will help take the industry to the next level – enabling even higher frame rates and resolutions up to and beyond 8K, greater flexibility in display configurations including multiple monitor setups, as well as improved power efficiency.”
Enhancing Energy Efficiency
DP 2.0 additionally helps VESA’s new Panel Replay capability, which is designed to optimize the facility envelope and thermal efficiency of smaller end units, reminiscent of all-in-one PCs and laptops, with greater resolution shows. Just like the Panel Self Refresh functionality in Embedded DisplayPort (eDP), Panel Replay incorporates a partial replace function that permits the system video processor, or GPU, to update only the portion of the display that has changed because the video frame update, thus saving system power. Benefits embrace the power to recharge a tool more shortly whereas at the similar time using it.
