The official HDMI Forum has this week announced the release of version 2.1 of the HDMI Specification which is available on all HDMI 2.0 supported devices offering a range of higher video resolutions and refresh rates, including 8K60 and 4K120 together with resolutions up to 10K. As well as higher resolutions HDR formats are also supported, and as you would expect bandwidth capability has also increased up to 48Gbps which will be supported by the new Ultra High Speed HDMI Cable. The HDMI Specification Version 2.1 is backward compatible with earlier versions and has been developed by the HDMI Forum’s Technical Working Group. Expect more supporting devices, cable and support to roll out during Q1-Q3 2018.
Specifications and features of the new HDMI 2.1 resolution standard 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.
