SAN JOSE, Calif. – January 4, 2017 – The Video Electronics Standards Association (VESA®) today announced its early certification program for video source and display products using DisplayPort™ High Bit Rate 3 (HBR3), the highest data link rate supported by the DisplayPort standard version 1.4 published in March 2016. DisplayPort interfaces with HBR3, which are now available in consumer products, can drive 8K video resolution using a single connection, as well as multiple 4K displays. Key applications supported by HBR3 include high-performance gaming, augmented and virtual reality (AR/VR), and television broadcasting.
The new DisplayPort HBR3 Early Product Certification Program includes a comprehensive test plan that covers supported features and capabilities. Leading DisplayPort compliance test laboratories, including Allion Labs and Granite River Labs (GRL), now offer early product certification for VESA member companies as well as testing services for products in development. In early December, many of VESA’s 230-plus member companies also participated in a test event held in Taiwan to certify product interoperability in order to ensure good user experience.
Data bandwidth represents the maximum rate of digital information, typically expressed in gigabits per second (Gbps), that can be transmitted across an interface. DisplayPort’s new HBR3 data rate supports a total bandwidth of 32.4 Gbps when using all four lanes in the DisplayPort or USB Type-C connector, at 8.1 Gbps per lane. This provides a combined audio/video payload data rate of 25.92 Gbps from the video source to the display device, which represents a 50 percent increase in bandwidth compared to DisplayPort-enabled systems today that use the HBR2 data link rate introduced in DisplayPort version 1.2. By using the DisplayPort Multi-Stream feature, this bandwidth can also be shared among multiple monitors connected to a dock. HBR3 also enables the support of 4K at a 60Hz frame rate using only two lanes, which is important for DisplayPort Alt Mode application on the USB Type-C interface as it frees the other two high-speed lanes of the USB Type-C connector for SuperSpeed USB operation.
“VESA made HBR3 available to developers with the release of DisplayPort version 1.3 in September 2014, and then rolled it into DisplayPort 1.4, which we published last March,” said Jim Choate, compliance program manager for VESA. “Now that 8K and VR content is starting to become available, we determined that a program similar to our successful DisplayPort Alt Mode Certification effort would be key to encouraging HBR3 compliance and further ecosystem growth for these advanced video technologies.”
Early product developers who take advantage of the DisplayPort HBR3 Early Product Certification Program gain the ability to use the DP Certified logo on their products. While certification is currently in the early stages, VESA has already demonstrated compliance with 8K sources and sinks. As of this date, products from AMD, NVIDIA, RealTek and MSTAR have been certified, while many more products from VESA member companies are undergoing certification. Many VESA member companies are working on HBR3 capability, spurred in part by Japan’s stated commitment to broadcast 2020 Summer Olympics proceedings in 8K, which will make a robust HBR3 ecosystem a necessity.
In addition to including support for HBR3, DisplayPort 1.4 incorporates new capabilities that facilitate utilizing the USB Type-C connector. It is the first DisplayPort standard to take advantage of VESA’s Display Stream Compression (DSC) technology, which facilitates High Dynamic Range (HDR) and 8K video across the USB-C connector. Examples of increased display resolution with DP 1.4 include 8Kp60Hz HDR deep color and 4Kp120Hz HDR deep color.
VESA will be showcasing HBR3-enabled products at the Consumer Electronics Show (CES) in Las Vegas, Nev., January 5-8, 2017 at the DisplayPort booth #20612 in the Las Vegas Convention Center, South Hall (S1). Demonstrations will include a gaming system driving a 4K at 120 Hz display, and two 4K at 60 Hz monitors driven by a single DisplayPort output.]]>
SAN JOSE, Calif. – December 13, 2016 – The Video Electronics Standards Association (VESA®) today announced the completion of its compliance test specification (CTS) for products incorporating the USB Type-C™ connector and the DisplayPort™ Alternate Mode (“Alt Mode”) standard. The new CTS documents allow VESA members to have their products compliance tested through VESA’s Authorized Test Centers (ATCs) worldwide, or by completing self-testing and posting their certified product information to VESA’s database. The CTS is currently undergoing final review and will be released next month.
The DisplayPort Alt Mode standard enables a USB-C connector and single cable to deliver full DisplayPort audio/video performance, with SuperSpeed USB data, and up to 100 watts of power. DisplayPort Alt Mode is natively supported by both standard USB-C connectors and cables. With the new CTS, DisplayPort is also well ahead of other standards organizations’ efforts to develop competitive USB-C Alt Mode specifications.
“The full spec was developed with the assistance of VESA member companies and electronics OEMs via numerous man-hours spent participating in well-attended VESA member compliance test events, called VESA PlugTest events, as well as in VESA hosted platform interoperability and test events,” said Jim Choate, VESA compliance program manager. “The engineering time spent to hone the spec will yield productivity savings going forward, as the ecosystem of CTS-certified products continues to grow.”
Completing full DisplayPort Alt Mode certification offers a number of benefits. It imparts reliability and predictability—so not only can OEMs feel confident designing the DisplayPort Alt Mode into their end products, but also consumers can purchase products touting full certification and be able to trust that they will work properly, with no worries about interoperability or compatibility issues. Lack of certification can create risks with respect to product functionality, as well as safety.
VESA published the DisplayPort Alt Mode in September 2014. Developed jointly between VESA and the USB 3.0 Promoter group, the DisplayPort Alt Mode enables the highest display performance available, combined with the USB Type-C connector’s high-speed data transfer and power delivery functions. Earlier this year, VESA published the latest version of the DisplayPort standard, v1.4, with new capabilities such as video transport compression, which facilitates High Dynamic Range (HDR) and 8K video across the USB Type-C connector.
Other key benefits of DisplayPort Alt Mode include:
Products fully certified as DisplayPort USB-C Alt Mode-compatible to date include leading chipsets, notebooks, monitors and laptops. As the ecosystem continues to grow, many more product certifications are expected to be complete during the first half of 2017.
New consumer product demonstrations showcasing the advanced capabilities and industry-leading performance of the DisplayPort Alt Mode standard will be on display at the Consumer Electronics Show (CES) in Las Vegas, Nev., January 5-8, 2017 at the DisplayPort booth #20612 in the Las Vegas Convention Center, South Hall (S1).

SAN JOSE, Calif. – June 8, 2016 – The Video Electronics Standards Association (VESA®) today announced the official launch of its early certification test program for products incorporating the new USB Type-C™ connector and the DisplayPort™ Alternate Mode (“Alt Mode”) standard. Using the DisplayPort Alt Mode standard, a USB Type-C connector and cable can deliver full DisplayPort audio/video performance (driving monitor resolutions of 4K and beyond), SuperSpeed USB data, and up to 100 watts of power. DisplayPort is the only display interface alt mode natively supported by both standard USB-C connectors and cables. The new DisplayPort Alt Mode over USB-C Early Product Certification Program is intended to help ensure interoperability early in the development cycle.
“During new-technology development, products often are ready to ship before compliance test programs are complete. Conformance testing, however, is still vital to helping ensure a smooth roll-out and positive user experience with early products,” said Jim Choate, compliance program manager for VESA. “To help USB Type-C product manufacturers address this challenge, VESA created the DisplayPort Alt Mode over USB-C Early Product Certification Program to help speed both the path to compliance and time to market for new products.”
The DisplayPort Alt Mode over USB-C Early Product Certification Program includes a comprehensive test plan that covers all supported features and capabilities. Currently, leading test laboratories Allion Labs and Granite River Labs (GRL) are executing to these test plans as part of the early certification program. VESA also organizes and sponsors PlugTest events throughout the year, in the U.S. and Taiwan, at which VESA member companies can participate in official testing activities.
Early product developers who take advantage of the DisplayPort Alt Mode over USB-C Early Product Certification Program gain the ability to use the DP Certified logo on their products. Nearly a dozen tablets, laptops and monitors have been certified through the pilot phase of this early certification program, including products from Intel (Skylake reference design), Dell, Asus, HP and LG Electronics. Several dozen more certified products are expected to be available by the end of the year.

SAN JOSE, Calif. – March 1, 2016 – The Video Electronics Standards Association (VESA®) today announced it has published version 1.4 of the DisplayPort (DP) audio/video standard. The first major update to DisplayPort since version 1.3 was released in September 2014, DP 1.4 is also the first DP standard to take advantage of VESA’s Display Stream Compression (DSC) technology. DSC version 1.2 transport enables up to 3:1 compression ratio and has been deemed, through VESA membership testing, to be visually lossless. Together with other new capabilities, this makes the latest version of DP ideally suited for implementation in high-end electronic products demanding premier sound and image quality.
DisplayPort is a packet-based, extensible protocol for transporting video and audio data. Initially introduced as a new external interface, its flexibility has enabled its adaptation to embedded displays and incorporation into other connectors like the new reversible USB Type-C™ interface and Thunderbolt™. Its Multi-Stream Transport (MST) capability enables high-resolution support of multiple monitors on a single display interface.
In September 2014, VESA published DP 1.3, which has been the baseline for new system development. DP 1.3 increased 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-percent increase over the previous DP 1.2a specification. DP 1.3 added extra protocol flexibility to enable more seamless operation over the USB Type-C connector in the form of the DisplayPort Alt Mode. The increased link rate increased the uncompressed display resolution support up to 5K x 3K (5120×2880), and also upped the MST resolution, enabling simultaneous use of two 4K UHD monitors, each with a pixel resolution of 3840×2160, when using VESA Coordinated Video Timing.
DP 1.4 further builds on the capabilities of the standard’s prior incarnations. The use of video transport compression enhances the ability to take advantage of the USB Type-C connector, enabling both high-definition video and SuperSpeed USB, while also facilitating High Dynamic Range (HDR) and 8K video across the DisplayPort or USB-C connector. Examples of increased display resolution with the new standard include 8Kp60Hz HDR deep color and 4Kp120Hz HDR deep color. Other key new features include:
“This significant update to the DisplayPort standard is vital to continued growth of adoption for both DP and DSC, particularly in such fast-growing markets as digital television and automotive infotainment,” said VESA Board Chair Alan Kobayashi, fellow and executive R&D management for Smart Connectivity Group at MegaChips Technology America. “New applications are demanding displays with better resolution, wider color gamut, and increased dynamic range. Consumers and others are also recognizing the value and ease-of-use associated with running multiple displays on one interface, which is another area we addressed in this new release with MST improvements. We believe the tools provided in this new DP standard release will enable a quantum leap forward in display quality, which leverage DSC compression along with transport of high-quality audio and video content.”]]>
SAN JOSE, Calif. – January 27, 2016 – The Video Electronics Standards Association (VESA®) today announced it has released version 1.2 of the Display Stream Compression (DSC) Standard. An extension to the feature set offered in version 1.1, DSC v1.2 was developed to support a wider range of display applications—in particular, externally connected displays such as PC monitors and televisions. A key feature of DSC v1.2 is its ability to provide native compression of the YCbCr 4:2:0 and 4:2:2 video formats commonly used in digital TVs.
Developed as an industry-wide compression standard for video interfaces that features low latency and visually lossless performance, DSC is currently integrated into standards used for embedded display interfaces within mobile systems. These include the VESA embedded DisplayPort (eDP™) Standard v1.4b and the MIPI Display Serial Interface (DSI) specification v1.2 and later versions. Since its initial introduction in April 2014, the DSC standard has achieved broad adoption in smart phones and tablets, and will be used in future notebook PCs. Examples of mobile processors that currently make use of DSC 1.1 include the NVIDIA Tegra® X1 and the Qualcomm® Snapdragon™ 820.
Dale Stolitzka, principal engineer at Samsung Display and chair of the VESA Display Stream Compression Task Group, noted, “This update to DSC greatly expands adoption opportunities for the standard, which includes within the automotive infotainment and digital TV markets. The update retains all the functionality of the prior version, while adding significant capabilities that will allow makers of a wide range of advanced displays to take advantage of DSC’s many benefits.”
The forthcoming VESA DisplayPort™ (DP) 1.4 specification will be the first DP standard to take advantage of DSC 1.2, which is backward compatible with DSC 1.1. A side-by-side comparison of the two versions can be found at http://www.vesa.org/news-events/press-kits/.
The new capabilities in DSC 1.2 will allow the standard to be utilized not only for mobile displays, but also for emerging high-definition TVs. Key features include:
“IP availability to the semiconductor industry plays a vital role in enabling this important compression standard for advanced, high-resolution displays,” said Alain Legault, VP of IP products for Hardent. “Our DSC-compliant encoder and decoder IP cores provide a low-risk, proven solution, allowing manufacturers to rapidly integrate the standard and meet their time-to-market windows.”
Added Craig Wiley, senior director of marketing for Parade Technologies and VESA board member, “The display industry is moving in exciting directions, and through the collaboration of our more than 230 member companies and liaisons with other standards organizations, VESA’s publication of DSC 1.2 enables a standardized display interface compression codec the will unleash a new level of display performance capability across multiple ecosystems. Similar to other VESA standards, DSC is available for use in display interface standards published by other organizations—further strengthening its value compared to proprietary standards that can’t match its visually lossless, low-power image compression.”]]>
SAN JOSE, CA – December 8, 2015 – The Video Electronics Standards Association (VESA®) today announced it has reached a new membership milestone, with more than 230 member companies on its roster. The developer of multiple video standards, VESA attributes much of this growth to the ongoing increase in adoption of the DisplayPort™ standard, with the new USB Type-C interface contributing to this rapid rise. Multiple products incorporating the USB-C interface have been introduced during the past year, and those that include video sources also incorporate the DisplayPort over USB-C™ protocol, formally known as the DisplayPort Alt Mode, either as an extended feature on the USB Type-C connector or included with Intel’s Thunderbolt™ interface.
DisplayPort Alt Mode is the only alt mode natively supported by both standard USB-C connectors and cables. Devices supporting DisplayPort Alt Mode on a USB Type-C connector can 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 also use an appropriate adapter to drive an HDMI, DVI or VGA display. All adaptors and converter cables comply with all USB Type-C characteristics, including reversible plug orientation.
According to Bill Lempesis, executive director of VESA, “DisplayPort’s Alternate Mode USB-C extension, which we introduced in September 2014, delivers full DisplayPort audio/video performance (driving 4K and higher resolution), SuperSpeed USB data and up to 100 watts of power—all over a single cable. Consumer electronics manufacturers are just now ramping up the use of USB-C on their products, which further accelerates the adoption of DisplayPort as the A/V standard of choice for driving 4K and higher resolution from PCs on down to mobile devices.”
Apple’s latest 12-inch Macbook is the first notebook that incorporates USB Type-C as a video port, using the DisplayPort Alt Mode, as well as its power port. Other currently available products that utilize USB-C connectivity, with DisplayPort Alt Mode for A/V transport, include Google Chromebook Pixel, Microsoft Lumia 950 and 950XL, and Lenovo Yoga 900. More examples of consumer products incorporating USB-C with DisplayPort Alt Mode will be unveiled at the upcoming Consumer Electronics Show (CES) to be held January 6-9, 2016 in Las Vegas, N.V.
New specs broaden VESA’s reach
VESA continues to expand in other ways, as well. The association is in the final stages of preparing two new specifications to be formally released in early Q1 2016:
In addition, VESA recently released Embedded DisplayPort (eDP) standard version 1.4b, making the standard production-ready for incorporation into integrated displays and personal electronic devices such as smart phones and tablets. By mid-2016, systems will begin to incorporate eDP v1.4b, and adoption of the standard should continue for several years.
Building the ecosystem
To continue meeting the needs of its growing membership base, VESA has expanded its DisplayPort Compliance Program. In the past year, VESA has added a full-time compliance manager, expanded compliance test development, and has held three DisplayPort PlugTest events well-attended by vendors of DisplayPort- and DisplayPort Alt Mode-enabled devices, including chips, systems, cables, adapters and docking accessories, as well as by test equipment vendors. VESA has also hosted three educational user workshops/seminars in Asia and exhibited DisplayPort demonstrations at various trade events this year.
Latest developments at CES 2016
At CES, a number of demos will be showcased in the VESA DisplayPort booth #20531 in the Las Vegas Convention Center South Hall, highlighting the benefits of DisplayPort for computing, digital displays and consumer electronics. These include:

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 firstname.lastname@example.org.]]>
