The latest HDMI spec has been released.
The HDMI Forum has officially announced the launch of version 2.1 of the HDMI spec. The updated specification is now available to all HDMI 2.0 adopters, and offers updated support for resolutions as high as 10K, Dynamic HDR, and an expanded bandwidth of up to 48Gbps.
"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.
The new HDMI 2.1 spec is backwards compatible with previous versions and includes several new or expanded features like 8K60Hz and 4K120Hz playback, along with up to 10K playback for commercial AV, industrial, and specialty usages. Likewise, the specification also provides Dynamic HDR capabilities, allowing for content with scene-by-scene or even frame-by-frame high dynamic range adjustments through supported displays. 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. The cable also features very low EMI (electro-magnetic interference) with wireless devices.
Additional features supported by the new HDMI 2.1 spec also include eARC (enhanced audio return channel) compatibility for connecting to audio devices, and enhanced refresh rate features to reduce lag, screen tearing, and delays during gaming, virtual reality, and media switching. Likewise, there's also a new Auto Low Latency Mode to automatically set the ideal latency setting for smooth, lag-free, and uninterrupted playback.
