HDMI Forum Inc. official statement:
"HDMI 2.0 does not define new data cables and connectors and interfaces, so it can maintain perfect downward compatibility with HDMI 1.x, and the existing type 2 data cables can be used directly."
The HDMI Forum Inc. organization announced that the HDMI 2.0 standard specification It has been completed and released, greatly enhancing the support for 4K UHD transmission and improving on multiple video and audio technologies.

-Simultaneous transmission of multiple audio streams to up to four users
－ Support 21: 9 ultra wide screen display
-Dynamic synchronization of video and audio streams

HDMI 2.0 does not define new data cables and connectors and interfaces, so it can maintain perfect downward compatibility with HDMI 1.x, and the existing type 2 data cables can be used directly. As for whether the current device can be upgraded to HDMI 2.0, there is currently no trend in this regard, and manufacturers need to update hardware and firmware.
HDMI Forum Inc. also specifically pointed out that HDMI 2.0 does not replace HDMI 1.x, but is based on the latter's enhancement. Any device that wants to support HDMI 2.0 must first ensure basic support for HDMI 1.x.
