Plug a USB-C screen into a USB-C port. Will it work?
Maybe? If the manufacturer has wired the port to the GPU for DP/HDMI alt mode it might.
… but you’ve used this display on this laptop before?
Try another port! Nope, still nothing.
Maybe it’s the cable? Rummage around through your cables and try a few out. Hope you don’t have any from the 2010s because there’s a good chance they’ll ruin your device.
The screen works! But performance is terrible, why? It’s running in DisplayLink mode.

You give up and suffer through.
