The HDMI Licensing Administrator, the group that defines and licenses HDMI standards, has some confusing requirements around the HDMI 2.1 standard. The group did away with HDMI 2.0 in 2017, and display makers should stick with HDMI 2.1 going forward — even without the essential features of the newer standard.
All of this comes from a statement the HDMI Licensing Administrator sent to TFT Central. In short, the HDMI 2.0 standard “doesn’t exist” anymore, and display designers should mark any HDMI 2.x display as supporting HDMI 2.1 as long as they support one new feature. The features of

The HDMI Licensing Administrator doesn’t see that big of a difference. In an email, the group told me that HDMI 2.0 was deprecated in November 2017, and that the features of HDMI 2.0 are now a subset of

That was until VESA, the organization behind standardized display mounting holes and the DisplayPort connection, created the DisplayHDR standard. Instead of the Wild West of
“A manufacturer needs to only support one 2.1 feature (such as eARC, for example) to call a device HDMI 2.1-compliant. However, they need to also state which features the device supports — so as to be clear what features the device supports. This is important so consumers won’t think a 2.1-enabled device supports all features,” the group wrote in an email.
We don’t have a major problem with HDMI 2.0 and
The job of any computing standard is to standardize complex, unapproachable technology. You don’t need to worry about the number of connectors in the USB 3.0 port versus a USB 2.0 one — just look for the blue port and know that USB 3.0 is much faster. Standards create space between technology and products and help demystify marketing.
HDMI is a port, but it’s also a standard. Each new number should mean something, but under the current guidance, they don’t need to. I’m in favor of well-informed customers, but the opportunity for manufacturers to be deceptive under HDMI’s current guidance is too high.
It brings into question the point of having a standard at all. If
