SAN JOSE, CA – October 27, 2015 – The Video Electronics Standards Association (VESA®) today announced it has published the Embedded DisplayPort (eDP) standard version 1.4b. This new release takes the original eDP 1.4 standard to production-ready status, incorporating a number of key protocol refinements and clarifications resulting from VESA member companies’ product development efforts. These enhancements to the eDP standard were specified to further optimize interoperability and time to market for developers of integrated displays and personal electronic devices, enabling improved flexibility of system implementation, reduced device complexity and lower bill of materials (BOM) costs.
Since the original publication of the eDP 1.4 standard more than two years ago, the PC and tablet industry has worked together within VESA to refine the specification as eDP 1.4-enabled components and products have been developed. As with eDP 1.4a, published in early 2015, the eDP 1.4b standard incorporates features of the VESA DisplayPort (DP) Standard v1.3 (December 2014). The GPUs and CPUs that support DisplayPort 1.3 can also drive the eDP 1.4 interface.
“From the onset, the development of eDP 1.4 has been all about power optimization,” stated Craig Wiley, senior director of marketing at Parade Technologies and editor of the DisplayPort 1.4 Standard. “Prior to eDP 1.4, eDP provided the highest performance and most optimized hardware interconnect, but not the lowest-power display interface for a given display resolution. As the largest supplier of eDP-enabled Sink devices, Parade is routinely pushed by chip set, panel, and platform OEMs to reduce device power, which has the benefit of reducing system form factors and extending battery life. eDP 1.4 puts eDP on parity with any other embedded interface regarding power consumption. Even with its added complexity, eDP is now more attractive even to the smallest devices because of its advantages. Along with our OEM partners, Parade believes that the eDP 1.4b release now represents the final eDP 1.4 implementation, and is now introducing Tcon products based on this standard.”
According to Bill Lempesis, executive director at VESA, “Since its introduction in 2008, eDP has become a central system element within the mobile computing market space. The standard has continued to retain its lead in display performance, supporting embedded panels with resolutions as high as 8K. We look forward to seeing systems incorporating the finalized standard come to fruition next year, broadening the number of consumers receiving clear, crisp visual information delivered by eDP 1.4 on their laptops, tablets, all-in-one PCs and possibly even smart phones.”
Like the previous eDP 1.4a standard, eDP 1.4b specifies four high-speed HBR3 lanes between the graphics adapter and display, with each lane operating at an 8.1 Gbps link rate. The lanes can be divided up between two or four independent panel segments, or used all together for a total theoretical payload bandwidth of 25.92 Gbps. One update to the original eDP 1.4 standard, which lowers system BOM cost, is an addition made to the Selective Update protocol for Panel Self Refresh. When sending the sub-frame video block for the partial update region, the Selective Update command from the video source now includes the Y-axis coordinate (line number) of where the region begins, instead of just the X-axis coordinate. Because this requires less precision in the asynchronous time base of the sink device, there is no need to include a discrete quartz crystal or crystal oscillator, as required by the original eDP 1.4 standard.
Another update to the standard is reduced granularity of the X- and Y-axis of the selective update region. Lowering the granularity can reduce the complexity of the display’s remote frame buffer implementation, thereby simplifying internal video compression implementation without diminishing the advantages of eDP 1.4.
Refinements were also made to the Selective Update protocol, as well as to the Multi-SST Operation (MSO) feature and the use of Display Stream Compression (DSC), Advanced Link Power Management (ALPM), and the auxiliary channel-based frame synchronization. Some of these refinements were made to simplify system design while others were made to further clarify implementation. Other parts of the standard were also updated to improve clarity and reduce ambiguity, minimizing the hurdles to launching the eDP 1.4 ecosystem.
While eDP 1.4b represents the latest VESA Embedded DisplayPort standard, systems in production today are using displays built to eDP 1.3 and earlier. By mid-2016, systems will begin to incorporate eDP 1.4b, and the final standard should continue to increase in adoption and be used in production for several years. In the meantime, VESA members will begin discussing plans for eDP 1.5, which will take advantage of new features that will be introduced in the future release of DisplayPort 1.4. The eDP 1.4b standard is available to VESA members. More information is available at www.vesa.org.]]>
NEWARK, CA – June 1, 2015 – The Video Electronics Standards Association (VESA®) today released Version 2.0 of the VESA Multiple Projection Common Data Interchange (MPCDI) Standard. Developed by VESA’s Multi-Projector Automatic Calibration (MPAC) Task Group, the standard creates a standard data format for multi-projector alignment systems, allowing these systems to produce data that can be easily utilized and integrated by a range of devices, programs and displays. The newest update includes a number of changes intended to mitigate color differences that arise when blending different projectors, enabling greater performance with respect to color consistency, brightness and intensity.
Modern solid-state imaging-based projection systems use fixed pixel numbers and positions. To shape the picture to fit a screen or to overlay an object, it is necessary to modify the shape of the image content in the signal. The techniques involved include edge blending, warping and pixel mapping. Introduced in July 2013, the MPCDI specification seeks to standardize these techniques across multiple manufacturers’ hardware and software offerings.
Version 2.0 of the MPCDI Standard builds on these efforts to allow for color correction so that individual projectors being blended together can be color matched regardless of brand, projector type or projector technology. Full 3D lookup tables are supported so that even DLP projectors, which traditionally are very difficult to color match, can be supported by multi-projector setups.
The new additions to the standard include:
· Color definitions – Formatting and storage of lookup tables are defined, along with input color-to-blending-to output color mapping equations and associated use cases.
· Color XML specifications – To store the definitions, the XML header was modified to allow pointing to the appropriate files and storage of the non-file correction parameters.
· Revised extension example – The original extension example – a color lookup table storing a series of .png files – is now covered in the standard directly. The new example provided is a lookup table for distortion and correction for chromatic aberration, with a separate red-green-blue (RGB) warp.
When combined with the existing standard, these new parameters further enable free interchange of data structures that provide a video definition for both content and intensity of colors that have been altered to allow conformance of multiple images for display as a continuous single image.
“Multi-projection systems are a cornerstone technology for a growing number of markets. These include high-end entertainment venues, military and other training simulators, and air-traffic control systems, as well as emerging virtual reality environments,” said Bei Yang, creative technology executive, Walt Disney Imagineering Research & Development, Inc. “With Version 2.0, we can bring more stability in both geometry and color quality than ever before to projection used in our theme park attractions.”
Also included in the definition of VESA’s MPCDI Standard are geometric data, intensity, color, and topographic information about each of the displays. The purpose of this definition is to simplify the transition between technologies during the lifecycle of a display system.
“Once again, VESA’s MPAC Task Group has worked with the industry to anticipate and address a key requirement for multi-projection implementation,” said Alan Kobayashi, chairman of the VESA Board of Directors. “VESA has a large portfolio of standards addressing areas including display interfaces, video parameters including timing, and compression, and MPCDI has extended our reach into multi-projector systems – in turn, broadening our impact within the display and electronics industries.”]]>
eDP 1.4a takes advantage of the VESA Display Stream Compression Standard (DSC), which is also used by MIPI DSI and external display interfaces, including future versions of DisplayPort and DisplayPort Alt Mode for the USB Type-C connector. Moreover, VESA has begun work on an Advanced DSC (A-DSC) protocol that will be optimized for higher-resolution embedded and external displays. New enhancements for DisplayPort are currently in the works that specifically target consumer applications and the USB Type-C connector. These include even higher data rates and the use of DSC with the addition of Forward Error Correction.
VESA will also feature the following demonstrations at MWC:
Display Stream Compression (DSC)
Demonstrates compressed vs. uncompressed video (up to 3:1) side-by-side to showcase the visually lossless performance of this new standard. VESA’s new DSC standard will enable display resolutions beyond what is available today.
Demonstrates a new display performance level enabled by the latest DisplayPort v1.3 standard, which will enable 5K @ 60Hz displays through a single cable without the use of compression
Demonstrates the ability to send DisplayPort, super-speed USB, and charging power through a single USB Type-C connector and cable. DisplayPort Alt Mode, developed jointly between VESA and USB, will enable the highest display performance available, along with the high speed data transfer and power delivery functions offered by the USB Type-C connector.
Demonstrates the ability to connect several monitors to a single port on a video source device, such as a laptop or computer, using a daisy-chain or hub configuration. The latest DisplayPort v1.3 standard with High Bit Rate 3 (HBR3) mode can support two 4K UHD (3840 x 2160) displays at 60Hz refresh rate at 24-bit pixel visual quality using the VESA video timing that is used with DisplayPort connections when the Multi-Stream feature is enabled.
“DisplayPort technology is very easy to integrate into mobile device system on chips (SoCs),” said VESA Executive Director Bill Lempesis. “Together with being a royalty-free open standard, this is making it an increasingly popular choice for new mobile devices, both for the internal and external display interface. We look forward to smartphone makers beginning to integrate DisplayPort into their products via the DisplayPort Alt Mode for USB Type-C connectors.”
The VESA booth will be located in Hall 5, Stand 5K70, at the Fira Gran Via Exhibition Center in Barcelona. Media interested in meeting with VESA during the Mobile World Congress can contact David Moreno at email@example.com.]]>
NEWARK, CA – February 9, 2015 – The Video Electronics Standards Association (VESA®) today published the Embedded DisplayPort (eDP) Standard version 1.4a. Replacing eDP v1.4, published in February 2013, eDP 1.4a enables a higher video data transfer rate for increased panel resolution, greater color depth and higher refresh rates. It also incorporates the VESA Display Stream Compression (DSC) Standard v1.1, and includes a new segmented panel architecture that enables higher panel integration. These and other refinements were made to the eDP 1.4a standard to take advantage of higher GPU video performance and newer display technologies, while also enabling reduced system power and form factor.
The eDP v1.4a standard leverages the VESA DisplayPort (DP) Standard v1.3, published in September 2014, as a base specification. That standard’s new higher HBR3 link rate, which operates at 8.1 Gbps per lane, is now also part of eDP v1.4a. With both HBR3 and the DSC v1.1 standard included, the latest eDP standard can support embedded panels with up to 8K resolution. For embedded display applications, DSC is most often used to decrease video interface data rate or wire count, as well as reduce display frame buffer size, thereby reducing system power usage to extend battery life. It also enables reductions in system complexity and form factor.
An entirely new feature in eDP v1.4a is “Multi-SST Operation,” or MSO, which supports a new type of display architecture that VESA calls “Segmented Panel Display.” Segmented Panel Display is designed to enable thinner, lighter and lower-cost panels that use less power. In operation, MSO allows the four high-speed eDP data lanes within the eDP interface to be divided up between either two or four independent panel segments. For lower resolutions, two lanes can be used to support two panel segments. This panel segmentation enables a higher level of integration on high-resolution displays; each segment can contain a separate timing controller with integrated source drivers.
According to Vice President Bong-Hyun You of Samsung Display Co., Ltd., “The Multi-SST Architecture enables greater design flexibility and power savings in new LCD panel technologies for embedded high resolution displays. Samsung proposed this feature in order to permit panel makers to make even broader usage of the eDP interface in advanced panels, as well as reduce panel thickness, reduce power draw, and reduce cost.”
eDP 1.4a also includes refinements to the partial update capability for Panel Self Refresh (PSR) that was introduced in eDP 1.4. Partial update enables the system video processor, or GPU, to update only the portion of the display that has changed since the video frame update, further saving system power.
According to Craig Wiley, senior director of marketing at Parade Technologies, VESA board member, and editor for eDP 1.4a, “The adoption of eDP for embedded displays is now positioned for growth as eDP 1.4a has become highly optimized, especially at resolutions above quad HD. Compared to other embedded interfaces, it has the richest feature set along with the lowest power, wire count and EMI radiation, particularly when used with high-resolution panels. It will continue to evolve, along with DisplayPort, but with its own unique features specifically optimized for embedded applications such as all-in-one PCs, notebooks, tablets and smart phones.”
It is anticipated that eDP 1.4a will be used within systems by 2016. The eDP v1.4a Standard is available to VESA members. For more information, please visit www.vesa.org.

NEWARK, CA – December 16, 2014 – The Video Electronics Standards Association (VESA®), developer of the DisplayPort™ standard created as the ultimate digital display interface, today reported that DisplayPort adoption, VESA membership and DisplayPort-related specification development have all increased over the past year. This points to the growing demand for DisplayPort and related standards, fueled by displays with 4K and higher resolution, as well as smaller devices with more flexible connectivity.
DisplayPort device certification grew to 1,395 devices to date in 2014, up from 805 devices at the beginning of the year. In 2014, VESA added 13 new member companies for a total of 224 members. Also during this past year, VESA released several DisplayPort-related standards, including DisplayPort 1.3, DisplayPort Alt Mode on USB Type-C, DockPort and Display Stream Compression.
“DisplayPort was developed as a PC to monitor interface, and those markets are where it is currently seeing great success. DisplayPort penetration into PCs is expected to increase over 26 percent annually through 2018. In addition, LCD PC monitor penetration is expected to grow at 56 percent per year,” said Brian O’Rourke, senior principal analyst at IHS. “DisplayPort benefits from its high throughput, which can easily accommodate HD video bandwidths, as well as its integration into PC chipsets from all major vendors.”
“Momentum for DisplayPort is picking up at a steady clip, thanks to a number of emerging technology applications that require the degree of flexibility and performance that the DisplayPort standard enables,” said VESA board of directors chair Alan Kobayashi, fellow and executive R&D management for DisplayPort Group at MegaChips Technology America. “We currently count among our partners more than 200 of the world’s largest semiconductor and electronics companies, who support the DisplayPort standard because they recognize the advantages it affords compared to older standards such as DVI and VGA, as well as HDMI, for advanced products such as forthcoming 8K video displays.”
DisplayPort Roots Remain Strong
Originally developed by the PC industry through VESA, DisplayPort quickly became the next-generation video/audio interface for desktop and portable computer systems. Highly extensible and royalty-free, the standard offers the highest display performance available, as well as unique capabilities such as multiple monitor support. Initial adoption by system OEMs has been driven by ease of integration into chips designed for computers, tablets, phones and displays.
New DisplayPort Developments
While originally intended to be used with its own specified connector, the flexibility and extensibility of DisplayPort has taken it in new directions. Similar to USB, DisplayPort is based on a data packet structure, and has the ability to be easily transported across different connection types and even with other data. This packetization is also what makes it flexible while being backward compatible, and allows it to support various format converters, including DisplayPort to VGA, DVI and HMDI adaptors.
The Thunderbolt™ standard developed by Apple and Intel, as well as the VESA DockPort™ standard, utilizes DisplayPort protocol to transport display and audio data. In 2015, products will be launched using the new USB Type-C connector that also support DisplayPort over this connector, using the DisplayPort Alt Mode standard published by VESA earlier this year. In addition, the DisplayPort protocol is supported by the WiGig standard, unveiled last year by the Wi-Fi Alliance.
On another front, Embedded DisplayPort (eDP) is becoming the embedded display interface of choice for very high-resolution displays in all-in-one PCs, notebooks and tablets. In early 2015, VESA will release eDP version 1.4a, which includes support for 5K x 3K resolution, borrowing from DisplayPort version 1.3.
eDP 1.4a also supports VESA’s new Display Stream Compression (DSC) standard, released in April 2014. DSC was defined in collaboration with the MIPI Alliance and is optimized for portable system embedded display applications. VESA is currently beginning development on a similar standard for displays requiring a higher compression rate that is also intended for industry-wide use in other display interface standards.
Another key development announced earlier this year is the addition of AdaptiveSync to the DisplayPort standard. AdaptiveSync enhances gaming action and video playback through active frame rate control, providing smoother and better-quality images. It also allows seamless reduction in the display refresh rate, lowering system power and extending battery life.

Adv-DSC is planned to target applications that require a lower bits per pixel (bpp) compressed bit rate than DSC v1.1, i.e. significantly less than 8bpp, while still providing visually lossless subjective coding quality at least as good as DSC v1.1. In exchange for such improved compression, Adv-DSC will require more complex encoders and decoders than DSC v1.1.
The VESA DSC Task Group seeks input from other standardization bodies and potential users of Adv-DSC regarding their specific applications of and requirements for a new coding system standard.
This Call for Requirements seeks specific requirements for a new coding system (Adv-DSC) that will target a lower bpp compressed rate than DSC v1.1 with greater complexity than DSC v1.1 and much less complexity than JCT-VC’s HEVC (High-Efficiency Video Coding) with Screen Content Coding Extensions. Responses should indicate the applications envisioned for Adv-DSC, and specific requirements including:
Please include other relevant requirements or flexible control of the coding system not specifically mentioned above.

NEWARK, CA (21 October 2014) – The Video Electronics Standards Association (VESA®) will offer a free, comprehensive half-day workshop covering the capabilities, technical background and compliance test plans for DisplayPort 1.3 and DisplayPort Alternate Mode (‘Alt Mode’) on USB Type-C Connector. Announced last month, these two DisplayPort standards significantly expand the capabilities and user benefits for the widely used audio/video (A/V) interface.
The DisplayPort Alt Mode on USB Type-C Standard combines DisplayPort A/V data, SuperSpeed USB data and 100W of power onto a single cable and connector with the convenience of reversible plug orientation and cable direction. DisplayPort 1.3 increases the maximum transport rate to 32.4 Gbit/sec, enabling a single DisplayPort cable to drive multiple 4K displays, 4K at 120Hz or 5K displays. These new capabilities and benefits enable many new use cases for computers, tablets, smartphones, displays and docking stations, while maintaining compatibility with VGA, DVI and HDMI 2.0 through inexpensive adapters.
Co-sponsored by VESA and Allion Test Labs, the free half-day workshop will occur:
When: Thursday November 13, 2014 from 1:00 PM to 4:30 PM CST
Where: The Westin Taipei

NEWARK, CA (22 September 2014) – The Video Electronics Standards Association (VESA®), working in liaison with the USB 3.0 Promoter Group, today announced the publication of the DisplayPort Alternate Mode (“Alt Mode”) on USB Type-C Standard. Using the DisplayPort Alt Mode, a USB Type-C connector and cable can deliver full DisplayPort audio/video (A/V) performance, driving monitor resolutions of 4K and beyond, SuperSpeed USB (USB 3.1) data and up to 100 watts of power–over a single cable. The DisplayPort Alt Mode can also drive adaptors that support the huge installed base of existing DisplayPort, HDMI, DVI, and VGA displays.
VESA utilized the Alternate Mode functional extension of the USB Type-C specification in the development of this new Standard. The DisplayPort Alt Mode repurposes some or all of the four existing SuperSpeed USB lanes to deliver full DisplayPort performance, and uses other signaling available in the USB Type-C connector for DisplayPort’s AUX channel and HPD (Hot Plug Detection) function. This enables computers, tablets, smartphones, displays, and docking stations to implement the new USB Type-C connector at both ends while using the DisplayPort Standard over USB Type-C to transmit high-resolution A/V along with USB data and power.
Devices supporting DisplayPort Alt Mode on a USB Type-C connector can also connect to an existing DisplayPort device using a reversible USB Type-C to DisplayPort converter cable. Video source devices that support DisplayPort Alt Mode on a USB Type-C connector can use an appropriate adaptor to drive an HDMI, DVI or VGA display. All adaptors and converter cables will comply with all USB Type-C characteristics, including reversible plug orientation and cable direction.
“The USB Type-C specification was developed to provide consumers with a robust connector for everything from mobile devices to PCs, and when combined with SuperSpeed USB 10 Gbps and USB Power Delivery, it truly enables a single cable solution for the market,” said Jeff Ravencraft, USB-IF President and COO. “The USB-IF is also in the process of developing joint port identification guidelines. We’re working with VESA to ensure consumers can recognize when DisplayPort Alt Mode is supported on USB Type-C devices.”
Like USB, DisplayPort uses a packetized data structure and differential AC-Coupled signal “lanes” that carry high speed data with an embedded clock. This allows the same electrical circuits and cables to carry either SuperSpeed USB data, at up to 10 Gbps per lane, or DisplayPort, at up to 8.1 Gbps per lane, as defined in the new DisplayPort 1.3 Standard. Early implementations of DisplayPort Alt Mode USB Type-C devices will likely use existing DisplayPort 1.2a capabilities that support up to 5.4 Gbps per lane. Using 5.4 Gbps across all four high-speed lanes will support up to 4K (4096 x 2160) display resolutions at a 60Hz frame rate with up to 30-bit color.
By leveraging USB Type-C’s flexibility, the DisplayPort Alt Mode can choose to transmit on just one or two of the four available lanes, so that the other two lanes can be used for SuperSpeed USB data at the same time. In a docking station connection, for example, the use of two lanes for DisplayPort at 8.1 Gbps per lane would allow simultaneous transfer of SuperSpeed USB data (up to 10 Gbps in each direction) while also supporting a 4K UHD (3840 x 2160) DisplayPort monitor. The dock can also be configured with DisplayPort protocol converters to support HDMI, VGA and/or DVI monitors. When using all four lanes for DisplayPort Alt Mode, which could drive a monitor with up to 5K (5120 x 2880) resolution, USB 2.0 data can still be carried across the USB Type-C connection using separate pins dedicated for that function.
“DisplayPort has played a vital role in advancing display performance and connectivity for platforms that are increasingly integrated and compact,” said Craig Wiley, Senior Director of Marketing at Parade Technologies, VESA Board member, and VESA Marketing Task Group Chair. “In addition to the dedicated DisplayPort connector, the DisplayPort Standard has become an important ingredient in other wired interfaces, such as ThunderBolt™, DockPort™, MyDP™, and Embedded DisplayPort™. The opportunity to utilize the USB Type-C specification to develop the DisplayPort Alternate Mode helps further VESA’s vision of common-place high performance video interfaces.”

Newark, CA (15 September 2014) – The Video Electronics Standards Association (VESA®) announced the release of the DisplayPort 1.3 audio / video (A/V) standard. An update to the widely used DisplayPort 1.2a standard, this latest version increases the maximum link bandwidth to 32.4 Gbps, with each of four lanes running at a link rate of 8.1 Gbps/lane—a 50% increase from the previous version of the DisplayPort standard. Allowing for transport overhead, DisplayPort’s 32.4 Gbps combined link rate delivers 25.92 Gbps of uncompressed video data.
The increased bandwidth enables higher resolution monitors, including recently announced 5K monitors (with pixel resolutions of 5120 x 2880) using a single DisplayPort cable, without the use of compression. It will also enable higher resolutions when driving multiple monitors through a single connection using DisplayPort’s Multi-Stream feature, such as the use of two 4K UHD monitors, each with a pixel resolution of 3840 x 2160, when using VESA Coordinated Video Timing.
DisplayPort 1.3 continues to support video conversion to VGA, DVI and HDMI. DisplayPort 1.3 adds support for HDCP 2.2 and HDMI 2.0 with CEC (Consumer Electronics Control), which enhances DisplayPort’s utility for television applications, including 4K video with copy protection. The new standard adds support for the 4:2:0 pixel structure, a video format commonly used on consumer digital television interfaces, which enables support for future 8K x 4K displays.
DisplayPort 1.3 also enhances DisplayPort’s value for multi-function interfaces that combine data transport, A/V transport and other capabilities on a single cable. It further refines protocols that enable DisplayPort to share a single cable with other data types. With its higher 8.1 Gbps per-lane link rate, DisplayPort 1.3 can support a single UHD monitor with 60Hz refresh and 24-bit color over two lanes, while assigning the remaining two lanes to increase capacity for alternate data types, such as SuperSpeed USB data as allowed in DockPort™. DisplayPort is the A/V transport standard used by DockPort, Thunderbolt™ and other wired and wireless multi-function interface standards.
“While becoming a mainstream video standard, DisplayPort continues to be at the cutting edge of A/V transport,” said VESA Board of Directors Chair Alan Kobayashi, Fellow & Executive R&D Management for DisplayPort Group at MegaChips Technology America. “These new enhancements to DisplayPort will facilitate both higher resolution displays, as well as easier integration of DisplayPort into multi-protocol data transports, which will satisfy consumer’s desire for simplicity and ease-of-use.”
The DisplayPort standard is offered to VESA members without any license fee. For more information about DisplayPort, please visit http://www.displayport.org or connect with us on YouTube.
