I hope more display manufacturers adopt this standard, because DisplayPort rocks. Read more in PC World’s article.]]>
The Video Electronics Standards Association (VESA®) today announced that a new wave of consumer electronics devices featuring DisplayPort® as the only display interface is sweeping the industry. Driven by demand for higher display performance, some of today’s hottest brands are leveraging DisplayPort to both increase display capability and to reduce the number of system ports needed. Apple was early adopter with DisplayPort and then Thunderbolt, which is DisplayPort-compatible, and now other leading companies including Microsoft®, Google®, Dell™ and Lenovo® are among other VESA members that offer DisplayPort-only products. These new products include the Microsoft Surface Pro with Windows® 8 Pro, the Google Chromebook™ Pixel, Dell’s XPS 13 Ultrabook and XPS 12 Convertible Touch Ultrabook, Lenovo’s ThinkPad® X1 Carbon Ultrabook, ThinkPad X1 Carbon Touch Ultrabook and the Lenovo ThinkPad Helix Ultrabook Convertible.
For the consumer, the DisplayPort interface provides the highest available display performance and offers backward-compatibility with existing displays using video adaptors. Video adaptors for converting DisplayPort to VGA, DVI and HDMI™ are widely available. For the system company, DisplayPort allows full integration and power savings, enabling sleeker system design and longer battery life. DisplayPort also reduces interference with wireless devices and has other technical advantages including the ability to add new features while maintaining backwards compatibility.
Some new devices on the market are starting to enable optional DisplayPort 1.2 features such as HBR2 (High Bit Rate 2), which enables support of 4Kx2K displays (Ultra HD) at 60Hz frame rate, which is not possible using other video interfaces through the use of a single cable. Another DisplayPort 1.2 feature becoming available is Multi-Stream Technology (MST), which allows support of multiple monitors through a single cable, using a video hub or daisy-chainable displays. More DisplayPort 1.2 enabled systems with HBR2 and/or Multi-Stream will become available in 2013.
“The higher-performance system products on the market, such as the new Surface Pro, continue to migrate more towards DisplayPort. For the consumer, this provides the ability to enjoy high quality video and audio and use the increasing number of DisplayPort-enabled display devices. For the OEM it eliminates the need for alternate display interfaces and has other advantages,” said Craig Wiley, chairman of the board of directors at VESA. “It’s encouraging to see the system companies embrace the DisplayPort ecosystem that was developed by personal computer industry. One objective of DisplayPort was to enable a single Display interface, and with many DisplayPort-enabled displays and adaptors now available it now makes sense to do this.”

The display performance of this device is so important that it’s even in the name, so it’s no wonder that Google opted to make this a DisplayPort-only device for the external display connection. Some of you may be asking “where is the HDMI port?” By using DisplayPort, the HDMI output becomes obsolete since simple adaptors can be used for HDMI and VGA displays. The DisplayPort output also allows high-performance DisplayPort-enabled displays to be connected. DisplayPort has the ability to support very high display resolutions, color depths, and refresh rates when compared to the other display types. The end result is a better visual experience all through the one DisplayPort interface. Choosing to only include DisplayPort also helps to make this one of the lightest laptops we’ve seen.
Over the last twelve months, the number of certified DisplayPort products has increased by 80 percent, further establishing the DisplayPort ecosystem. With last year’s growth in DisplayPort products, VESA expects to see a continued influx in DisplayPort-only products coming to the market. In fact, in the first months of 2013, we have already seen DisplayPort-only products hit the market from Lenovo, Dell, Microsoft and now Google.

Newark, Calif., January 31, 2013 – The Video Electronics Standards Association (VESA®) today announced the latest release of the DisplayPort Dual-Mode Standard. This release supports the next generation of Dual-Mode DisplayPort enabled personal computers and Dual-Mode DisplayPort cable adaptors, expected to be available to consumers later this year. Among several refinements to improve interoperability, the updated standard enables a higher data rate for DisplayPort-to-HDMI cable adaptors, providing support for HDMI 1.4 display resolutions such as 1080p 3D at 60Hz, and Ultra HD (4K x 2K) up to 30Hz frame rate, as well as 1080p with deep color.
“The first Ultra HD displays were introduced in 2012, but today’s Dual-Mode DisplayPort-to-HDMI cable adaptors limit display resolution to 1080p,” said Craig Wiley, senior director of marketing at Parade Technologies, and VESA Board of Directors chairman. “For a personal computer to fully support HDMI 1.4 or deep color, today a separate HDMI output is needed. This updated DisplayPort Dual-Mode Standard version 1.1 enables full support of HDMI 1.4 video modes, and 1080p deep color, using a simple cable adaptor plugged into the system’s DisplayPort output. This helps to reduce the number of interface ports needed on a Personal Computer, which is desirable as form factors shrink.”
Developed by VESA’s nearly 200 leading industry member companies, the DisplayPort Dual Mode Standard defines the requirements for Dual-Mode DisplayPort source devices and Dual-Mode DisplayPort cable adaptors. DisplayPort was developed to provide a single video interface that both provides advanced features as well as interoperability with legacy displays including VGA and DVI, and HDMI. The new Dual-Mode Standard is in line with this objective by enabling the support of the latest HDMI standard, HDMI 1.4. In addition to releasing the DisplayPort Dual-Mode Standard Version 1.1, VESA is also releasing an updated DisplayPort Dual-Mode Cable Adaptor Compliance Test Specification, version 1.1. Conformance to the updated Compliance Test Specification, or CTS, is required for using the DisplayPort logo with a Dual-Mode Cable Adaptor.
A Dual-Mode DisplayPort source is a device, such as personal computer, that can logically output either DisplayPort or TMDS (Transitional-Minimized Differential Signaling) from the DisplayPort output connector, enabling the support of DisplayPort, DVI, and HDMI monitors. An additional device, specifically a Dual-Mode DisplayPort cable adaptor, is required to convert the mechanical connector, as well as the electrical aspects of the signal, to output that is compatible with a DVI or HDMI cable and display. A Dual-Mode DisplayPort source automatically detects the presence of a plugged-in Dual-Mode DisplayPort cable adaptor and provides the DVI or HDMI signal, as required, to support the connected DVI or HDMI monitor.
Prior to the updated Dual-Mode Standard release, Dual-Mode cable adaptors were limited to a TMDS clock rate of 165MHz providing support for display resolutions up to 1080p with 60Hz and 24 bits color. In this latest specification, a new Dual-Mode cable adaptor configuration is defined that enables a TMDS clock rate of up to 300MHz. While the DVI standard limits TMDS clock rates up to 165MHz, the HDMI 1.4 specification allows TMDS clock rates up to 297MHz, enabling the support of 1080p 3D at 60Hz, or Ultra HD (4K x 2K) up to 30Hz frame rate.
With the release of this new VESA specification, existing adaptors will now be referred to as “Type 1” adaptors, and the new adaptors as “Type 2.” A Type 2 adaptor will be backward compatible with an existing Dual-Mode DisplayPort source device, but it will only support up to a 165MHz TMDS clock rate unless it is used with a “Type 2 enabled” Dual-Mode DisplayPort source device. Some existing systems will be software updatable to support Type 2 adaptors. A Type-2 enabled Dual-Mode DisplayPort Source devices, together with a Type 2 Dual-Mode DisplayPort-to-HDMI adaptor, will enable support for HDMI 1.4 display modes such 1080p 3D at 60Hz, or Ultra HD (4K x 2K) up to 30Hz frame rate, as well as 1080p with deep color. Type 2 adaptor prototypes are currently available from multiple suppliers.

NEWARK, Calif., January 24, 2013 – The Video Electronics Standards Association (VESA®) today announced the completion of requirements for the Display Stream Compression Standard, which is anticipated to be published in late 2013. The association first initiated efforts for a common industry-wide standard in September 2012 and since formed alliances with other standards bodies for contributions.
VESA’s objective for the Display Stream Compression Standard is to enable increased display resolutions over existing interfaces, while further optimizing power and hardware for portable systems. To ensure a broad scope of the more encompassing DSC standard, VESA established a liaison with Joint Photographic Experts Group (JPEG), through its parent committee under the joint organization of the International Organization for Standardization and the International Electrotechnical Commission, ISO/IEC JTC 1/SC 29, and with the MIPI Alliance. The shared goal is to have a common standard that can be used by the various organizations for interface standards.
VESA’s Display Stream Compression task group completed the definition of requirements in late 2012 and announced a call for proposals in January 2013. The standard is expected to be published for use by the end of 2013. In contrast with other image or video compression standards, the proposed Display Stream Compression Standard targets a relatively low compression ratio and emphasizes visually-lossless performance, high data throughput, low latency, low complexity, and includes special considerations geared for future display architectures.
“Display manufacturers gain from display stream compression in many ways,” said Dale Stolitzka, VESA Display Compression Standard Task Group chairman and member of Samsung Display’s San Jose R&D Lab . “Display technology continues to improve resolution and color depth in small and large panel sizes. However, we are approaching the limit of how much data we can transfer over the existing display interfaces without increasing power, complexity and number of wires, which is the wrong direction for a mobile device that runs on battery power. The Display Stream Compression Standard will allow us to continue to enhance display resolution without compromising display quality and at the same time make devices smaller and lighter, with longer battery life.”
In current practice, virtually all digital display interfaces send uncompressed pixel data from the system graphics or video source to the display. As display resolutions continue to increase, the data rate across the video electrical interface has also increased. Higher display refresh rates and color depths push rates up even further. For example, a 4K display at 60 frames per second with a 30 bit color depth requires a data rate of about 17.3 gigabits per second, which is the current limit of the DisplayPort specification. Higher interface data rates demand more power, can increase the interface wire count, and require more shielding to prevent interference with the device’s wireless services. These attributes increase system hardware complexity and weight and are undesirable for today’s sleek product designs.
Participation in the Display Stream Compression Standard development is available to all VESA member companies and through inter-organization liaison agreements.

INTERNATIONAL CES 2013, LAS VEGAS, January 8, 2013 – The Video Electronics Standards Association (VESA®) today announced the rapid growth of certified DisplayPort™ products during 2012. Over the last twelve months, the number of certified DisplayPort products increased by 80 percent, further establishing the DisplayPort ecosystem as planned by the personal computer industry to increase display and system performance.
During 2012, DisplayPort certifications have increased across all device categories and have expanded into new categories. Certification in computer monitors has grown 95 percent, projectors 100 percent, and graphics cards 18 percent, and there was a 20 percent increase in cable products. New categories experiencing certification growth include handheld devices, notebooks and adaptors. With the introduction of MyDP (Mobility DisplayPort) the DisplayPort ecosystem has been further extended into the tablet and smartphone market.
“Within the past year, we have seen a shift in the perception regarding the value of DisplayPort by system manufacturers,” said Bill Lempesis, executive director, VESA. “The increasing adoption rate signals a vote of confidence in DisplayPort and the growing DisplayPort ecosystem. As consumers become accustomed to the various benefits and superior visual experiences, this will increase DisplayPort demand. We will see further grown of certified DisplayPort products and continued expansion into other categories, including in TVs, in the coming year.”
VESA’s DisplayPort standard is a high-bandwidth video interface designed to enable features not available with other electronic connections, delivering true digital imaging and audio through a single cable. DisplayPort is the only video interface that supports multiple displays and Ultra HD at 60 frames per second from a single video output. DisplayPort significantly enhances display performance by doubling the maximum data transfer rate enabling multiple displays and increasing display resolution, color depths, and refresh rates when compared to other display interfaces.
“While the adoption of DisplayPort has been drawn out over the past few years, the standard has been moving ahead steadily,” said Brian O’Rourke, senior principal analyst, display electronics, IHS iSuppli. “With DisplayPort’s widespread adoption in PC chip solutions, the standard is poised to have a successful year in 2013.”
At the International CES, VESA will be demonstrating various DisplayPort functionalities such as Multi-Stream (MST), daisy-chained monitors, Mobility DisplayPort (MyDP), Embedded DisplayPort (eDP) and High Bit Rate (HBR2). VESA will also showcase its exclusive feature of delivering Ultra HD resolution at 60 frames per second, a feature no other display standard is capable of doing today.
The International CES 2013 will be held January 8-11, 2013 in Las Vegas, Nevada. VESA’s technology demonstrations will take place at the DisplayPort booth #21431 in South Hall 1 of the Las Vegas Convention Center (LVCC).
