HDMI Forum, Inc. has announced the upcoming release of Version 2.1 of the HDMI Specification, which supports a range of Higher Video Resolutions and refresh rates including 8K60 and 4K120, Dynamic HDR, and increased bandwidth with a new 48G cable. Version 2.1 is backward compatible with earlier versions, 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.

“This new release of the Specification offers a broad range of advanced features for enhancing the consumer entertainment experience, as well as providing robust solutions to the commercial AV sector,” said Robert Blanchard of Sony Electronics, President of the HDMI Forum. “This is part of the HDMI Forum’s continuing mission to develop specifications for the HDMI eco-system that meet the growing demand for compelling, high-performance and exciting features.”

Features Include:

  • Higher Video Resolutions support a range of higher resolutions and faster refresh rates including 8K60Hz and 4K120Hz for immersive viewing and smooth fast-action detail.
  • Dynamic HDR ensures that 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.
  • 48G cables enable up to 48Gbps bandwidth for uncompressed HDMI 2.1 feature support, including 8K video with HDR. The cable is backwards compatible and can be used with existing HDMI devices.
  • eARC supports the most advanced audio formats, such as object-based audio, and enables advanced audio signal control capabilities, including device auto-detect.
  • Game Mode VRR features variable refresh rate, which enables a 3D graphics processor to display the image at the moment it is rendered for more fluid and better detailed gameplay, and for reducing or eliminating lag, stutter, and frame tearing.

The new specification will be available to all HDMI 2.0 Adopters and they will be notified when it is released early in Q2 2017.
