HDMI 1.4 was established to eagerly anticipate 4K as well as set particular requirements to allow support for it in the future (from 2009) by offering sufficient bandwidth for 4K video clip at as much as 24 frameworks per secondly. It’s since seen iterations as well as upgrades to HDMI 1.4 an as well as HDMI 1.4 b, however that’s once again ancient history in the video clip space.
The HDMI 2.0 spec was released in 2013, and also changed right into HDMI 2.0 a in 2015 and after that HDMI 2.0 b in 2016.
