HDMI Forum rejects AMD's HDMI 2.1 open-source driver

FYI: USB Type-C ports are DP ports on most modern laptops. You just need the correct cable (or a display with Type-C connector.) I have one of these https://www.club-3d.com/en/quick-view/2470/

(actually works both directions, e.g. if you have a portable display with only Type-C connectors like this https://www.hp.com/us-en/shop/pdp/hp-e14-g4-portable-monitor — BUT it can't power the display, you need to use another connection on the display for that.)

There is no HDMI over Type-C (there was an attempt at it, but it died. Probably for the better of not having even more Type-C confusion and interoperability issues.)

The "relevant devices" is surely referring to the displays here. I would love to go DP for everything but the best I can seem to find is computer monitors with 1 DP input and usually 2 or more HDMI. For living room type displays you won't find DP at all.

For PC displays on geizhals.eu, out of 3327 products:

   157 (4.7%) have  2 DP inputs
  2446 (74%)  have  1 DP input
   724 (22%)  have no DP input

Including USB-C ports,

   949 (29%)  have ≥2 DP inputs
  1806 (54%)  have  1 DP input
   572 (17%)  have no DP input

Compare HDMI:

  1350 (41%)  have ≥2 HDMI inputs
  1791 (54%)  have  1 HDMI input
   186 (5.6%) have no HDMI input

I agree it could be better but I don't think it's as bad as you make it out to be. Looking through the devices that have no DP input at all, 488 of the 572 have VGA inputs, which I'd say indicates an older generation of devices.

"Consumer" electronics (i.e. TVs) is a problem though, I'll agree.
