As high definition audio/video technology continues to advance, the specification for HDMI equipment and cabling is occasionally modified to ensure broad compatibility and maximum performance. Version 2.0 is the latest iteration of the HDMI spec, as issued by HDMI Licensing, LLC.
Per the HDMI specification, only four HDMI cable types exist: Standard Speed, Standard Speed with Ethernet, High Speed, and High Speed with Ethernet. The HDMI organization has put in place a rule that requires all HDMI cables to be marketed in this manner. Therefore, you will not see our cables marketed as HDMI 2.0 cables. Keep in mind that installing a cable supporting HDMI 2.0 features does not give your existing devices with previous HDMI specifications the ability to experience 4K x 2K resolution, 3D, audio return or Ethernet. New A/V equipment supporting these desired features is required in order to experience the newly specified features.
HDMI 2.0 delivers many new features to take your audio/video entertainment to the next level. Below are just a few of the features we think you will care about:

HDMI 2.0, which is backwards compatible with earlier versions of the HDMI specification, significantly increases bandwidth up to 18Gbps and adds key enhancements to support market requirements for enhancing the consumer video and audio experience.
HDMI 2.0 significantly increases bandwidth to 18Gbps and includes the following advanced features:
No, HDMI 2.0 is built on top of HDMI 1.x and any device that wants to implement HDMI 2.0 must first implement HDMI 1.x as a baseline requirement.
Yes, all HDMI versions are fully backward compatible with all previous versions.
No, HDMI 2.0 uses the existing connectors.
No, HDMI 2.0 features will work with existing HDMI cables. Higher bandwidth features, such as 4K@50/60 (2160p) video formats, will require existing High Speed HDMI cables (Category 2 cables).
Currently, there are no provisions for doing such an upgrade. Because of the new enhanced feature set, any such conversion would require hardware and/or firmware upgrades. If there are such conversions, it would come from the manufacturer. Please check with them directly.
No, the existing testing policies continue to apply to HDMI 2.0.
Each individual ATC will decide on when to offer HDMI 2.0 testing services. Please contact your local ATC for more information.
All HDMI 2.0 features must be compliance tested with the HDMI Compliance Test Specification (CTS) 2.0 and all HDMI 2.0 devices must also be compliant with the HDMI CTS 1.4b.
The HDMI 2.0 Compliance Test Specification (CTS) is expected to be released before the end of 2013.
