While the faster refresh rates are delivered to consumer TVs (8K60Hz and 4K120Hz) the HDMI Forum says that the 10K resolution is "supported for commercial AV, and industrial and specialty usages". The cable also features very low EMI emission and is backwards compatible with earlier versions of the HDMI Specification and can be used with existing HDMI devices.
The format includes high dynamic range (HDR) support to help ensure improved video performance with improved depth, detail, brightness, contrast and wider color gamut capabilities on a scene-by-scene or frame-by-frame sequence.
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).
Among other features, HDMI 2.1 also supports variable refresh rates, an automatic low-latency mode, and HDR metadata. But 120Hz-plus displays are already coming in the first quarter of 2018 in the form of glorious G-Sync HDR monitors by Asus and Acer, and Nvidia's next generation of graphics cards - hopefully due sooner than later - will presumably have the power to drive such demanding displays. Quick media switching (QMS) should get rid of that brief black screen when switching content.
According to details provided by the HDMI Forum, the new HDMI v2.1 specification will be backward compatible with all previous HDMI standards but will also need the new ultra high-speed HDMI cable for those new upgrades.
Back in January, the HDMI Forum-the trade association that develops the HDMI spec for video interconnects-outlined its plans for HDMI 2.1. Finally, Quick Frame Transport is there to reduce latency.
HDMI 2.1 also comes with eARC (Enhanced Audio Return Channel) support which supports most advanced audio formats such as Dolby Atmos and DTS X and provides a lossless audio experience compared to HDMI 2.0's ARC feature.
