The new HDMI 2.1 cables will allow faster refresh rates, including 8K resolution video at 60 frames per second and 4K at 120 frames per second – and it's that second feature that will be the real selling point for gamers and home cinema geeks, at least at first.
"We've increased resolutions and frame rates significantly," Jeff Park, Director of Marketing at HDMI Licensing, told TechRadar at CES 2017, adding that the Tokyo 2020 Olympic Games are going to be a driver for 8K TV content. "NHK [Japan's national public broadcaster] is going to push 8K120 as an actual broadcast stream, and many consumer electronics manufacturers want to hit that target, so we're laying the pipe to give the industry flexibility. It's practical stuff." Although it's about keeping HDMI at the bleeding edge, HDMI 2.1 can actually go ever further, supporting resolutions as high as 10K at 120Hz – though that kind of capability is a while away from being supported on commercial sets.
