HDMI FORUM RELEASES VERSION 2.1 OF THE HDMI SPECIFICATION

A Huge Leap Forward Supports Resolutions Up to 10K and Dynamic HDR and Introduces New Ultra High Speed HDMI Cable

SAN JOSE, California – November 28, 2017 – HDMI Forum, Inc. today announced the release of Version 2.1 of the HDMI® Specification which is now available to all HDMI 2.0 adopters. This latest HDMI Specification supports a range of higher video resolutions and refresh rates including 8K60 and 4K120, and resolutions up to 10K. Dynamic HDR formats are also supported, and bandwidth capability is
increased up to 48Gbps.

Supporting the 48Gbps bandwidth is the new Ultra High Speed HDMI Cable. The cable ensures highbandwidth dependent features are delivered including uncompressed 8K video with HDR. It features exceptionally low EMI (electro-magnetic interference) which reduces interference with nearby wireless devices. The cable is backwards compatible and can be used with the existing installed base of HDMI
devices.

Version 2.1 of the HDMI Specification is backward compatible with earlier versions of the specification, and was developed by the HDMI Forum’s Technical Working Group whose members represent some of the world’s leading manufacturers of consumer electronics, personal computers, mobile devices, cables and components.”

The HDMI Forum’s mission is to develop specifications meeting market needs, growing demands for higher performance, and to enable future product opportunities,” said Robert Blanchard of Sony Electronics, president of the HDMI Forum.

HDMI Specification 2.1 Features Include:

  • Higher video resolutions support a range of high resolutions and faster refresh rates including 8K60Hz and 4K120Hz for immersive viewing and smooth fast-action detail. Resolutions up to 10K are also supported for commercial AV, and industrial and specialty usages.
  • Dynamic HDR support ensures every moment of a video is displayed at its ideal values for depth, detail, brightness, contrast and wider color gamuts—on a scene-by-scene or even a frame-byframe basis.
  • The Ultra High Speed HDMI Cable supports the 48G bandwidth for uncompressed HDMI 2.1 feature support. The cable also features very low EMI emission and is backwards compatible with earlier versions of the HDMI Specification and can be used with existing HDMI devices.
  • eARC simplifies connectivity, provides greater ease of use, and supports the most advanced audio formats and highest audio quality. It ensures full compatibility between audio devices and upcoming HDMI 2.1 products.
  • Enhanced refresh rate features ensure an added level of smooth and seamless motion and transitions for gaming, movies and video. They include:
    • Variable Refresh Rate (VRR) reduces or eliminates lag, stutter and frame tearing for more fluid and better detailed gameplay.
    • Quick Media Switching (QMS) for movies and video eliminates the delay that can result in blank screens before content is displayed.
    • Quick Frame Transport (QFT) reduces latency for smoother no-lag gaming, and real-time interactive virtual reality.
  • Auto Low Latency Mode (ALLM) allows the ideal latency setting to automatically be set allowing
    for smooth, lag-free and uninterrupted viewing and interactivity.

The HDMI 2.1 Compliance Test Specification (CTS) will be published in stages during Q1-Q3 2018, and HDMI adopters will be notified when it is available.
