HDMI Forum Has Released The Latest HDMI Specification, HDMI 2.1

The HDMI Forum announced the upcoming release of version 2.1 of HDMI Specification. HDMI 2.1 supports a range of the higher video resolutions and refresh rates including 8K60 and 4K120, Dynamic HDR, and the increased bandwidth with a new 48G cable.

While increased resolution has a debatable effect on picture quality, especially at the smaller sizes, one thing that has making a noticeable difference on new TVs is high dynamic range (HDR).

Some of other improvements in the new version of HDMI include eARC support for object-based audio and advanced audio signal control, wider dynamic HDR, and “Game Mode VRR” allowing a GPU to change the refresh rate of the image on the fly.

Not all of the new features are aimed at the home theater crowd. Game Mode VRR is features a variable refresh rate, which not only leads to more fluid rendering of gameplay, but can also reduce the frame tearing and stuttering. More importantly to the gamers, it can also dramatically reduce input lag, making for much precise control over the game you’re playing.

Many of these features will require new 48G HDMI cables, which enable for bandwidth up to 48Gbps for 8K video with HDR. Fortunately, these cables will be backward compatible, so while you may have to go cable shopping, at least you will not have to worry about keeping multiple types of cables around.

As with previous versions of the specification, HDMI 2.1 and the cabling are backwards compatible to older equipment. The new specifications will be available to all HDMI 2.0 Adopters and they’ll be notified when it is released early in the second quarter of 2017.
