  • Small HDMI feature table

Backwards compatible with with earlier versions of the HDMI format, the new version HDMI 2.1 specification was developed by the HDMI Forum's Technical Working Group.

The HDMI forum has published the specs for version 2.1 and give gamers and multimedia perfectionists everything they could ever want for years to come.

In addition to the well-known 4K resolution, the new specification will work with higher resolutions such as 5K (5120x2160), 8K (7680x4320), and 10K (10240x4320). This cable will ensure users can properly display bandwidth reliant content, like 8K with HDR enabled. It also reduces interference with nearby wireless devices because it features exceptionally low EMI (electro-magnetic interference). Over the next nine months, the HDMI Forum will release compliance tests, and only then would we expect to see it become available in shipping products.

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.




Current HDMI 2.0 cables, referred to by some manufacturers as HDMI UHD, give a maximum video bandwidth of 18 Gbit/s, enabling HDMI 2.0 to carry 4K video at 60 Hz with 24 bit/px color dept. While the spec is backwards compatible, you will need a new Ultra High Speed HDMI cable to achieve the 48 Gbps bandwidth, thanks to the better shielding such cables have. Quick Media Switching aims to end jarring black screens when videos switch, and eARC lets HDMI's audio return channel handle lossless audio. The new feature list also includes Quick Frame Transport, a reduced-latency mode for games, mixed reality, and karaoke.

The HDMI Forum is an open trade association that guides the future direction of HDMI technology and develops new versions of the HDMI Specification.
