Brief summary of the problem: I have a RX 6800 XT connected to a LG B9 TV via HDMI. As both...

Alex Deucher:

The HDMI Forum has rejected our proposal unfortunately. At this time an open source HDMI 2.1 implementation is not possible without running afoul of the HDMI Forum requirements.

Because DisplayPort is run by VESA, who better understand the appeal of an open standard.

DisplayPort is open in name only. The specifications are locked behind membership (and requisite fees of ~$5k/yr - just enough to keep most hobbyists and the like out while being less than a rounding error for big companies).

That’s not the point of my comment, the point is that whatever hdmi is, it’s got very healthy competition, so there’s no real reason for anti-trust stuff

No it doesn’t, because it’s generally monitor manufacturers that add display port, and people who want to run on large tvs are SoL

That’s on the tv manufacturers though, it’s their choice.

When most TV manufacturers are part of the HDMI “standards” committee, they obviously have a vested interest in not using other technologies, especially when they provide many of the accessories used with TVs. If they allowed competing standards on their TVs, why would consumers buy their products instead of the competitors?

A choice they are making in favor of a tech cartel instead of what is best for their customers, which is the problem we want addressed
