Besides this, HDMI 2.0 also boasts of support for 4K video at a resolution of 3,840 by 2,160 pixels. The new standard is backward compatible with its earlier versions.

HDMI 2.0 also introduces new features that consist of the following:-

  • Up to 1,536kHz audio sample frequency for the highest audio fidelity
  • Simultaneous delivery of dual video streams to multiple users on the same screen

  • Support for the wide angle theatrical 21:9 video aspect ratio
  • Dynamic synchronization of video and audio streams
  • CEC extensions provides expanded command and control of consumer electronics devices through a single control point

Due to the fact the HDMI 2.0 standard is built on top of the existing HDMI 1.x specifications, the new standard's features will work with existing cables; however, its higher bandwidth features such as support for 4K video at Ultra HD resolution will require Category 2 HDMI (HDMI High Speed) cables.
