The HDMI 2.1 spec is so screwed up.
They're now calling HDMI 2.0, HDMI 2.1, arguing that all of the new features of the 2.1 spec are completely optional.
They're basically pulling a USB 3.0 is actually USB 3.1 gen 1, which is actually a USB 3.2 gen 1.
Which is obnoxious.

"Products can no longer get certified for 2.0 only for 2.1, and also 2.1 features are optional to implement, so popular features like 4k120, ALLM, VRR are not required," Brad Bramy, VP of marketing and operations for the HDMI LA, confirmed to Ars. "Manufacturers could only implement eARC, for example, and claim to be a 2.1-enabled device."Turns out that "HDMI 2.1" ports don't need to actually support HDMI 2.1 features | Ars Technica
