Display Port Standard Grows Due to Demand for 4K Video

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.
