> Why don't TVs support displayport?

For the same sorts of reasons that made it so for decades nearly every prebuilt PC shipped with an Intel CPU and Windows preinstalled: dirty backroom dealings. But in this case, the consortium that controls HDMI are the ones doing the dealings, rather than Intel and Microsoft.

"But Displayport doesn't implement the TV-control protocols that I use!", you say. That's totally correct, but DisplayPort has the out-of-band control channel needed to implement that stuff. If there had been any real chance of getting DisplayPort on mainstream TVs, then you'd see those protocols in the DisplayPort standard, too. As it stands now, why bother supporting something that will never, ever get used?

Also, DP -> HDMI active adapters exist. HDR is said to work all the time, and VRR often works, but it depends on the specifics of the display.
