The HDMI Licensing administration told TFT Central on record that it had no objections to display manufacturers labeling their own HDMI 2.0 monitors as “HDMI 2.1” monitors. The administration is simply concerned that all the companies selling HDMI 2.1 displays should identify the functionality available on each model.
All of the standards from HDMI 2.0 have been converted to the new HDMI standard with the release of HDMI 2.1. The HDMI 2.1 technology’s backward compatibility with prior generations of displays made this possible. However, the HDMI licensing group notes that HDMI 2.1 functions are entirely optional. In other words, it is up to display manufacturers to define which ones are supported on their products. To put it another way, almost every feature after the HDMI 2.0 spec is optional. This might become a major issue because users seeking a v2.1 monitor will now have to conduct their own research to ensure that the equipment they are purchasing is exactly what they want.

TFT Central has a summary of the statement from the HDMI Licensing Administrator, Inc. representative. Here are the key highlights:
1. HDMI 2.0 is no longer there so devices cannot claim that they are in compliance with v2.0.
2. All the feature includes in HDMI 2.0 are now a subset of v2.1.
3. All the new features of HDMI 2.1 are optional. In other words, it is up to the manufacturers to use them or not.
4. The manufacturers are required to mention every feature the device supports to make sure there is no confusion.
