HDMI recently released its newest specification, HDMI 2.1, and it is slated to take video to the next level.

 

Here is the 411 on HDMI 2.1:

·       eARC provides support for advanced audio formats such as object-based audio. It also allows for advanced audio signal control abilities including device auto-detect.

 

·       Game Mode VRR includes variable refresh rate, which permits a 3D graphics processor to display the image at the same time it is rendered. This provides gameplay with better detail and more fluidity, it also reduces or eliminates lag, stutter and frame tearing.

 

As with all HDMI desginated products, thorough testing must be done to garner the HDMI 2.1 seal of approval. In regards to earlier HDMI specifications, HDMI 2.1 will superceded 2.0b and will continue to refernce and rely upon the 1.4b specification. HDMI 2.0 adopters will automatically have access to the HDMI 2.1 specification, HDMI 1.4b adopters will not have access. HDMI 1.4b products will continue to be tested to the 1.4b requirements. HDMI 2.1 compliance test specifications were published last year. The timeline for beginning compliance testing for HDMI 2.1 will be decided by each individual authorized testing center.
