HDMI 2 Announced, HDMI 1 vs HDMI 2

HDMI 2.0 has been officially announced, and it gives a pretty good boost in audio and video quality. Announced by HDMI Licensing, the new connection standard boasts a bandwidth capacity of up to 18Gbps, which means it can carry 3,840 x 2,160 resolution video at up to 60fps. That’s pretty impressive. It also supports up to 32 audio channels. Below is a table that sums it all up.  Fortunately, the physical connector itself is unchanged—which is relief for anyone concerned about backwards compatibility. Expect to see devices using the new standard late this year.
