Now called HDMI 2.1b<\/a> following minor updates, the spec’s arrival brought new capabilities, starting with higher video resolutions and refresh rates. It supports 4K video at 120 Hz (higher with certain PC graphics cards), 8K video at 60 Hz, and even 10K video. HDMI 2.1b\u2019s speedy refresh rates mostly come into play with gaming, where it facilitates other advanced features like VRR (variable refresh rate) for more fluid gameplay as well as ALLM (auto low-latency mode) and QFT (quick frame transport) for reduced latency. The spec also supports all high-bitrate audio formats, including DTS Master Audio, DTS:X, Dolby TrueHD, and Dolby Atmos.<\/p>\n

Other notable features announced with HDMI 2.1 include HDMI eARC for lossless hi-res audio transmission between eARC-supported devices, and dynamic HDR support<\/a>, which allows for HDR content to be optimized for video scene-by-scene or even frame-by-frame.<\/p>\n
