HDMI 2.0

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.
