The HDMI Forum– a trade association that develops the HDMI spec for video interconnects has outlined its plans for HDMI 2.1. The specification has now been finalized, giving a definitive view of what’s in store for our video hardware.

In spite of a version number that suggests it’s only a minor update, the spec represents a significant step up from HDMI 2.0. Underpinning everything is a new cable, the Ultra High Speed HDMI Cable, supports data transfer rates of 48gigabits per second. The new cables are backward compatible with older HDMI specs—they use the same actual plugs and sockets—but support substantially faster connections than the 18Gb/s of HDMI 2.0, let alone the 10.2Gb/s of HDMI 1.4.

This means more resolution, higher frame rates, and more color depth.

With this type of new cabling, the HDMI can now support uncompressed 4K videos at up to 120fps, with high dynamic range color at up to 12bits per channel. You can further push in others; limit your framerate to 30fps, and the spec will support uncompressed 8K 12-bit video; use chroma subsampling and it can hit 60fps at the same resolution and color depth.

The latest HDMI 2.1 also allows video streams to go beyond the 48Gb/s with its new feature called Display Stream Compression. This feature compresses the video stream on the fly, allowing for notional data rates of up to 128Gb/s, for chroma subsampled 120fps 12-bit HDR 8K video. And if 8K isn’t enough pixels for you, there are a number of 10K formats supported for a 10,240×4,320 resolution, intended for specialized commercial applications.

A cool feature for gamers is the Variable Refresh Rate – think AMD FreeSync or Nvidia G-Sync. Quick Frame Transport promises to reduce latency, important for fast-pace games and VR.

The technology with also bring Dynamic HDR, which will deliver videos at its “ideal values” for contrast and color gamut. 10, 12 and 16-bit color is possible and you can use 4:4:4 chroma sampling. The cable has a raw bandwidth of 48Gbps, more than 4 times what HDMI 1.4 offers!

The HDMI 2.1 will take some time to come, and we’re not expecting it to hit the markets before the mid-2018.
