HDMI 2.1 released, 8K and 10K oriented, 48Gbit cables now
  • HDMI Forum, Inc. today announced the upcoming release of Version 2.1 of the HDMI Specification. This latest HDMI Specification 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 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.

    “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.”

    HDMI Specification 2.1 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 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 with earlier versions of the HDMI Specification 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.

  • Given that as of today, 18 Gbit/s aka "600MHz" capable HDMI cables are available in lengths to no more than 3 meters (and no manufacturer claims to be able to build longer ones that reliably work), I wonder what lengths of "48G"-cables will be offered.

    I for one am not willing to place my video source next to the TV.

  • @karl

    One of solutions is active cables with small amplifier.

  • Sure, but in the long run every cable standard that required active components didn't become a wide success for the simple reason that this makes cables expensive and even more prone to defects (due to the additional electric components and their possible incompatibilities at both ends).

  • Specification released

    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-byframe 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.

  • All NVidia upcoming 11xx GPU cards will have support for HDMI 2.1.

    It'll be one of main marketing points.

  • @Vitaliy_Kiselev I just feel Nvidia will not fully support the spec, and figure ways to Gimp the full HDMI 2.1 Spec on $700+ "Consumer Cards", with partial support for 10 bit color or Fake "HDR" to retain GSync proprietary garbage... Nvidia history shows they just can't help themselves... they come from same school as Canon and Nikon, no?

    Especially since Apple is ditching Open Graphics...

  • @NickBen

    Spec on $700+ "Consumer Cards", with partial support for 10 bit color or Fake "HDR"

    have no idea about any fake HDR. But 10bit limits on desktop are due to need to sell premium cards. It is old story.

  • Unfortunately, compliance testing protocols and procedures for HDMI 2.1 certification have not been announced yet for many product categories, meaning that it’s very unlikely that any 4K Ultra HDTVs available this year will carry the HDMI 2.1 connector.

    And they even tell you how you do not need it due to this

    The world’s still safe for you to go out and buy [today’s premium TV] products. You don’t have to panic with HDMI 2.1 coming down the pipe.
