Most USB-C devices really only support DisplayPort for video output.

There's an HDMI "alt mode", but almost no device uses that directly; most USB-C-to-HDMI adapters and cables are accordingly really combined USB-C to DisplayPort and DisplayPort to HDMI converters and translate one protocol to the other at the electrical and logical level.

it's not "almost", it's literally no device: there are no hosts and there are no cables. And it was killed officially this year, too.
