What are the key advanced features enabled by HDMI 2.0b

  • Enables transmission of High Dynamic Range (HDR) video
  • Bandwidth up to 18Gbps
  • 4K@50/60 (2160p), which is 4 times the clarity of 1080p/60 video resolution
  • Up to 32 audio channels for a multi-dimensional immersive audio experience
  • Up to 1536kHz audio sample frequency for the highest audio fidelity
  • Simultaneous delivery of dual video streams to multiple users on the same screen
  • Simultaneous delivery of multi-stream audio to multiple users (Up to 4)

HDMI 2.0b does not define new cables or new connectors. Current High Speed cables (Category 2 cables) are capable of carrying the increased bandwidth.


What is the testing policy for HDMI 2.0 products?
An  Adopter's first product in a designated product category that implements any function of the HDMI 2.0 specification needs to be submitted to an ATC for testing and pass all applicable and available HDMI compliance tests before shipment.

An Adopter's subsequent product in a designated product category that implements any additional function of the HDMI 2.0 specification should be submitted to an ATC for testing and pass all applicable and available HDMI compliance tests before shipment.


Can existing HDMI cables support the higher bandwidths of HDMI 2.0 Specification?
Yes, existing High Speed HDMI Cables (wire only) will support the new higher bandwidths (up to 18Gbps). 

HDMI 2.0 specification defined a new, more efficient signaling method, for speeds above 1.4b limits (10.2Gbps), to allow higher bandwidths (up to 18Gbps) over existing High Speed HDMI Wire Cables.
