USB-C display output uses the Display Port protocol
Can it use others, and is there a benefit? USB C makes a lot of sense; lower material usage, small, carries data, power and connects to almost everything now.
I believe USB-C is the only connector supported for carrying DisplayPort signals other than DisplayPort itself.
The biggest issue with USB-C for display in my opinion is that cable specs vary so much. A cable with a type c end could carry anywhere from 60-10000MB/s and deliver anywhere from 5-240W. What's worse is that most aren't labeled, so even if you know what spec you need you're going to have a hell of a time finding it in a pile of identical black cables.
Not that I dislike USB-C. It's a great connector, but the branding of USB has always been a mess.
I think that the biggest issue with dp over usbc is that people are going to try to use the same cable for 4k and large data transfers at the same time, and will then whine about weird behaviour.
4K works for mine (it's 3.2).
