HDMI 2.1 officially launched, supports upto 10K resolution


Today the HDMI Forum a group that manages HDMI standards officially announced the new 2.1 HDMI standard.

The HDMI Forum has published its latest HDMI v2.1 specification. The HDMI Forum says the HDMI 2.1 specification supports a range of A/V formats, including 8K video at 60Hz and 4K video at 120Hz.

HDMI 2.1 supports a bevy of new video outputs, including 4K and 8K video at a refresh rate of 60 Hz. The cable incorporates low EMI (electro-magnetic interference) to reduce interference with nearby wireless devices.

The HDMI Forum has a new spec for its widely-used connector.

Perhaps just as pleasing to your peepers as the higher resolutions and refresh rates is the delivery of Dynamic HDR to compatible TV screens.

HDMI 2.1 also has some enhanced refresh rate features specifically for smoother gaming.

It introduces some major improvements over the predecessor, HDMI 2.0, such as improved bandwidth speed of 48Gbps, up from 18Gbps seen in the predecessor. 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.

eARC (Enhanced Audio Return Channel) targets simplifying connectivity and supports the most advanced audio formats and highest audio quality. Furthermore, Quick Frame Transport (QFT) reduces latency for smoother no-lag gaming, and real-time interactive virtual reality. An Auto Low Latency mode allows source units to establish the ideal latency settings for different types of media, too. More resolution, higher frame rates, and more color depth. An open trade association, The HDMI Forum's mission is to foster broader industry participation in the development of future versions of the HDMI Specification and to further expand the ecosystem of interoperable, HDMI-enabled products.
