HDMI v2.1 specification officially released

30 Ноября, 2017, 14:12 | Author: Grady King
  • The latest version of the HDMI Specification has been released with support for a range of higher video resolution and refresh rates

The specification is available as of today to all HDMI 2.0 adopters.

The HDMI 2.1 specification is now available, which means TV/monitor makers can start making good use of it. The new version supports a range of A/V formats, including 8K video at 60Hz and 4K video at 120Hz.

HDMI 2.1's full specification has just been released - and it proves a forward-looking standard, able to cope with a range of higher picture resolutions and refresh rates that have yet to hit the market. Users will have to equip a new Ultra High Speed HDMI Cable, ensuring that uncompressed 8K video with HDR can be transferred, designed with exceptionally low EMI (electro-magnetic interference) properties.

The new spec supports 8K and even 10K resolutions, but those are better thought of as future-proofing or targeted towards commercial applications. This includes support for Variable Refresh Rate, which reduces stutter and tearing. Quick media switching (QMS) should get rid of that brief black screen when switching content. The new feature list also includes Quick Frame Transport, a reduced-latency mode for games, mixed reality, and karaoke.

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.

Even though the HDMI Forum released the new specification, adopters will need to conduct a compliant test to get the official nod from the group that their products work with HDMI 2.1. The HDMI Forum now has a membership of 92 companies, and is actively inviting more companies to apply for membership and help shape the future of HDMI technology.

FOR MORE INFORMATION on the HDMI 2.1 Specification or becoming an HDMI Forum member visit the HDMI Licensing Administrator, Inc. booth at CES 2018, LVCC South Hall 1 booth 20542.

Earlier this year, we first began hearing about the upcoming HDMI 2.1 specification, which is set to pave the way for 4K/120Hz and 8K/60Hz.
