HDMI 2.1 Supports Larger Bandwidth, Higher Resolutions

HDMI 2.1 will also theoretically be able to support dynamic HDR video.

The HDMI Forum today released more details about its HDMI 2.1 spec, and it includes support for technology like Dynamic HDR, and features enough bandwidth to support resolutions up to 10K. The mandatory Ultra High Speed HDMI cable can now carry up to 48 Gbps and allows for Display Strem Compression (DSC).

The new standard supports a whole host of new video outputs including 4K video at 120Hz and 8K video at 60Hz, along with support for video at 10K resolution. The previous spec, HDMI 2.0, had a significantly lower bandwidth at 18 Gb/s. HDMI 2.1 also allows for "dynamic HDR (high dynamic range)", which features the same high range of contrast and brightness in a scene-by-scene or even frame-by-frame basis.

In addition, a new Ultra High Speed HDMI Cable with 48Gbps bandwidth has been announced as part of the launch as well, helping to ensure support for high-bandwidth dependent features. Gamers in particular will be pleased with many of those, such as the Variable Refresh Rate which helps reduce frame tearing and lag, among other things. Likewise, there's also a new Auto Low Latency Mode to automatically set the ideal latency setting for smooth, lag-free, and uninterrupted playback. There's also Quick Media Switching, which is helpful for movies and video because it eliminates the delay (often displayed as a black screen) before content appears on the screen.

More information on the HDMI 2.1 Specification will be available at the HDMI Licensing Administrator, Inc. booth at CES 2018 being held in Las Vegas from January 9-12. These include an Ethernet channel, and the cable is backward compatible to work with existing devices.
