  • HDMI 2.1 Officially Releases, Makes Way For 10K Video

Now after several months of additional work, the HDMI Forum has finalized its specification, making HDMI 2.1 official.

While 4K resolution TVs, smartphones, and monitors are still the big upgrade for most consumers, we've seen traces of 8K devices hit the market, and 10K resolution is already a thing at the commercial level. 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 new standard supports a whole host of new video outputs including 4K video at 120Hz and 8K video at 60Hz, along with support for video at 10K resolution. 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.

Among other features, HDMI 2.1 also supports variable refresh rates, an automatic low-latency mode, and HDR metadata.

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. Variable Refresh Rate can reduce or even eliminate lag, screen tearing, and stuttering, and Quick Frame Transport helps with "smoother no-lag gaming and real-time interactive virtual reality". The new Quick Media Switching feature allows changes in refresh rates and resolution without the customary and annoying display blackout.

If you're looking for more information, check out the HDMI Forum's Release Presentation. The new Enhanced Audio Return Channel (eARC) is backwards-compatible with the existing ARC and has support for uncompressed and object-based audio formats like DTS:X and Dolby Atmos.
