Kicking off the IFA consumer electronics show in Berlin, the HDMI Forum has released HDMI 2.0. HDMI 2.0 introduces support for 4K (2160p) at 50 and 60 FPS, 3D playback at 4K resolution, up to 32 audio channels (up from a paltry eight), and some interesting features such as "dynamic auto lip-sync" and the ability to deliver dual video streams to multiple users on the same screen. The max throughput of HDMI 2.0 is a beefy 18Gbps (up from 10Gbps), and you'll be glad to hear that your stupidly expensive HDMI cable will continue to work with the new spec.
