A year later than expected, HDMI 2.0 has arrived, bringing support for higher-end high-resolution 4K TVs to the widely used video-audio connector technology. The previous, 2009-era version of the High Definition Multimedia Interface, HDMI 1.4, supports 4K “Ultra HD” video, but with some limits: at a resolution of 3840×2160 it worked at up to 30 frames per second, and at 4096×2160 it reached only 24fps. HDMI 2.0, though, can cram more bits down a high-speed HDMI cable — 18 gigabits per second rather than 10Gbps for HDMI 1.4. That means it supports 4K video signals up to 60fps, the HDMI Forum announced Wednesday at the IFA consumer electronics show in Berlin. The greater data transfer rates also means that HDMI 2.0 can carry dual video streams that can be shown simultaneously on the same screen. And it supports up to 32 audio channels.
