Following is information and insight from IHS Markit about our Interface Battleground Report.
- The number of devices adopting DisplayPort is expected to surpass devices with high-definition multimedia interface (HDMI) in 2019 by more than 23 million devices. This boost to DisplayPort is due to the support of Alternate Mode (Alt-Mode) over USB Type-C, mainly in Windows-based tablets, 2-in-1 PCs and smartphones.
- HDMI, including both native and Alt-Mode, will experience a five-year compound annual growth rate (CAGR) of 4.7 percent, growing from 856 million units in 2016 to slightly more than 1 billion units in 2021. This increase is directly related to the growth of the overall consumer electronics market.
- The combined share of DisplayPort Alt-Mode and HDMI Alt-Mode with USB-C from the total DisplayPort and HDMI markets is expected to grow from 1 percent in 2016 to 37 percent in 2021.
- The number of devices adopting DisplayPort Alt-Mode is expected to rise from 14 million units in 2016 to 920 million units in 2021, registering a five-year CAGR of 131 percent. HDMI Alt-Mode is not expected to make its way into the consumer electronics segment until the middle of 2018, with early adoption in digital-still cameras and video cameras.
While HDMI has been the undisputed leader in wired interfaces for video transfer in the consumer electronics world for many years, it will be eclipsed by DisplayPort, due to growing adoption of DisplayPort Alternate Mode (Alt-Mode) with a USB Type-C (USB-C) connector.
As the standard protocol for any consumer device transmitting or receiving a high-definition video signal, HDMI still boasts a larger installed base than all other related interface technologies in the consumer wired-video-interface world. The latest HDMI 2.1 specification will continue to drive the next generation of higher-performing consumer electronics products, answering consumer demand for more exciting entertainment options and providing a faster, smoother and more immersive user experience.
Devices with at least one HDMI or DisplayPort interface port are forecast to grow at a five-year CAGR of over 20 percent, from 1.1 billion devices in 2016 to 2.8 billion devices in 2021.
HDMI interface growth will be led by demand for UHD in TVs, set-top boxes, mobile PCs (i.e., laptops and notebooks), monitors and virtual reality (VR) headsets. All of these devices connect to TVs via native HDMI.
DisplayPort, which was introduced to replace video graphics array (VGA) and digital visual interface (DVI), is becoming more popular in the PC segment and in mobile phone applications. DisplayPort was released later than HDMI; however, the release of alternate-mode specification in 2014 gave a boost to this interface technology, in the form of USB-C DisplayPort Alt-mode.
In fact, HDMI Alt-Mode has not received greater adoption since its introduction in 2016, primarily due to the rise of DisplayPort Alt-Mode. Until now, HDMI Alt-Mode could only support the HDMI 1.4b version, with resolution up to 4K at 30 hertz (Hz), while DisplayPort Alt-mode provides a wider feature set, a double-sided USB-C cable and resolutions up to 8K at 60 Hz.
The combined market for native and Alt-Mode DisplayPort is, therefore, expected to dominate the wired video interface market for both the PC and wireless segments through 2021. DisplayPort Alt-Mode is forecast to remain the most popular USB-C Alt-Mode interface used by device makers.
