The new HDMI 2.1 specification (and cable) adds support for 10K, 8K HDR, and 4K at 120fps
Originally announced back in January and slated for a mid-year release, the HDMI 2.1 specification is just now making its debut on the world stage. Announced by the HDMI forum yesterday, the new specification offers users the ability to deal with 10K video resolution, as well as other data-intensive formats such as Dynamic HDR, uncompressed 8K HDR video, and 4K at 120fps.
A new Ultra High Speed HDMI Cable standard has also been announced that carries up to 48Gbps, and which is said to have ‘exceptionally low electro-magnetic interference’ to avoid conflict with other devices in the vicinity.
HDMI 2.1 is backwards compatible with earlier versions of the standard, as is the new high speed cable. For more information, visit the HDMI forum website.
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 high-bandwidth 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-by-frame 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.
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.
