HDMI Forum, Inc. today released Version 2.1 of the HDMI Specification which is now available to all HDMI 2.0 'adopters', or licensees. This latest HDMI Specification supports a range of higher video resolutions and refresh rates including 8K60 and 4K120, and resolutions up to 10K, with 'display stream compression'. Dynamic HDR formats are also supported, and bandwidth capability is increased up to 48Gbps. All headline features that were announced earlier in the year. so,is the fact that there will be a new cable with 48 Gbit/s capacity.

The new Ultra High Speed HDMI Cable ensures high-bandwidth dependent features are delivered including uncompressed 8K video with HDR, well only at the lower framerates, 120 frames per second requires a compression scheme branded 'DSC, Display Stream Compression'. HDMI Forum said 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.

HDMI 2.1 Specification released, to support 8K and Dynamic HDR

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.

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.
