HDMI 2.0

Posted on November 16, 2013 by KVMG-CMS   |  0 comments

HDMI 2.0 improves on HDMI 1.4 (which was released back in 2009), primarily providing increased bandwidth to better support Ultra HD and 4K.

HDMI 2.0 enhancements and features include:

  • Bandwidth (throughput) capacity is increased from 10.2Gbps (HDMI 1.4) to 18Gbps
  • 4K Ultra HD at 50/60Hz - i.e. 2160p50 and 2160p60 - four times the clarity of 1080p60
  • Up to 32 uncompressed digital audio channels (compared to HDMI 1.4's eight)
  • Up to 1536kHz audio sampling
  • Simultaneous delivery of dual video streams to multiple users (on the same screen)
  • Simultaneous delivery of multi-stream audio to multiple users (up to four)
  • Support for 21:9 aspect ratios
  • Dynamic synchronization of video and audio streams
  • Additional CEC extensions for remote controls


HDMI 2.0 is fully backwards compatible with HDMI 1.4 and it features the same 19-pin connectors.

HDMI 2.0 does not require new cables. Current high-speed Category 2 HDMI cables can handle the increased bandwidth.
