New Hisense TVs have USB-C DisplayPort support. Pretty cool, but realistically I don't see how it's different from HDMI from a usefulness standpoint.
Edit: It is cool I can plug my phone or laptop into the TV with one cable, no adapters, and get some power as well. For some reason it didn't work with my Steam Deck which was strange.
This. I was reading about some of the ugly hacks Valve has had to get around to use 2.1 on the steam machine. They (HDMI consortium, whatever its called) won't let you use 2.1 if your video drivers are FOSS. Since SM has open drivers for the AMD card it's leading to subobtimal video output at certain resolution/framerate combos (4K@120fps? Something like that), and they can't legally advertise support for HDMI2.1.
There absolutely are ways to do this, some motherboards have a DP-In connector that is routed to the USB4 ports. One example would be the ProArt X670E.
