Rise of USB Type-C Connector Drives Growth in DisplayPort

Rise of USB Type-C Connector Drives Growth in DisplayPort™ Standard Adoption, VESA Membership
VESA demos at CES 2016 will underscore value of deploying DisplayPort over USB-C™ for
mobile devices, notebooks and emerging 8K TVs
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:
Display Stream Compression (DSC) 1.2 will expand upon the capabilities of DSC v1.1 and include
enhancements for use in television, which will further enable the deployment of High Dynamic
Range (HDR) and 8K screen resolution for video.
DisplayPort 1.4 will be the first standard to take advantage of DSC 1.2. The use of video
transport compression will enhance the ability to have both high-definition video and
SuperSpeed USB, while facilitating HDR and 8K video across the USB-C connector.
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:
DisplayPort over USB-C – Many of the latest consumer products incorporating the new USB-C
connector and DisplayPort over USB-C will be on display, enabling the delivery of 4K
performance, SuperSpeed USB data and up to 100 watts of power in a single reversible plug.
Adaptive-Sync – VESA’s Adaptive-Sync addition to DisplayPort enhances gaming action through
active frame rate control while also reducing system power and extending battery life.
Display Stream Compression – DSC 1.1 will be demonstrated with compressed vs. uncompressed
video side-by-side to showcase the visually lossless performance of this standard, which enables
flexibility of transport, power savings, and resolutions beyond what is possible today.
Panel Self-Refresh – Demonstrates a key capability of Embedded DisplayPort (eDP), which adds
a separate frame buffer to the display panel and allows the host GPU / CPU to enter a low
power state when a static display image is encountered—thereby reducing power and extending
battery life.
