Quick one for you on HDMI 2.0 that can handle 4K now:
HDMI 2.0 is backwards compatible with earlier versions of the HDMI specifications, significantly increases bandwidth up to 18Gbps and adds key enhancements to support continuing market requirements for enhancing the consumer video and audio experience.
New HDMI 2.0 functionality includes:
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)
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
HDMI 2.0 does not define new cables or new connectors. Current High Speed cables (Category 2 cables) are capable of carrying the increased bandwidth.
“With the publication of the HDMI 2.0 specification, we are now soliciting input and proposals from member companies for the next HDMI Forum specification. We also encourage new members to join and participate in the development of the next HDMI specification.”
– Arnold Brown, Chairman of Board of Directors, HDMI Forum, Inc.
