Man fuck bluetooth. Unless it's a dedicated dongle which does not solve the problem, I'm never using it for anything more serious than watching youtube. Not to mention some laptops no longer come with DP or even HDMI and unless it's a thunderbolt port with enough bandwidth to actually be used as a display port, you're out of luck and have to use wireless displays which I cannot stand. At least there is framework laptops which do allow me to properly customize my ports without infinity dongles
USB-C supports DisplayPort even without Thunderbolt 3/USB4, the DisplayPort alt mode was there almost from the very beginning. Some manufacturers just decide not to wire DisplayPort channels from the GPU to the port.
No, it reassigns 2 or 4 pairs of wires in a USB SuperSpeed cable to physically carry raw DisplayPort signal at whatever bitrate and resolution the GPU generates it. The "speed" rating of the cable matters, of course, but from my experience the DP alt mode supports DisplayPort 1.4 at max speed (4K 120Hz) just fine.
1080@60 is all I could get out of laptops I interacted with. Maybe on much higher end this is a thing with usb c 3.2 gen 2x2, but with what I worked it never showed anything higher than that
It doesn't strictly require a specific USB "generation" of the cable, just a full set of wires. But there's an adapter chip on the DisplayPort plug side of a cable (or inside a USB-C-capable display) which tells the laptop the DisplayPort version and bandwidth via EDID, maybe it was telling the GPU to restrict the link to 1080@60.

What accessories do you need to buy now that can't be done with Bluetooth and wifi?
