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.

would be neat to somehow have a standard color coding. kinda how USB 3 is (usually) blue, maybe there could be thin bands of color on the connector?

better yet, maybe some raised bumps so visually impaired people could feel what type it was. for example one dot is USB 2, two could be USB 3, etc

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.

Yep, very true. I didn’t understand this until I couldn’t connect my Mac to my screen via the USB C given with the computer, I had to buy another (and order it in specifically). Pick up a cable, and I have no idea which version it is.

It’s also a bad connector…

The annular design makes such a strong connection that someone pulling on the wire the wrong way will rip the receptacle off the board. It should be standard for the cable to fail under stress instead of getting into a pissing contest with the smd ground/shield joints between the board and receptacle.

The little usbc ports also have way too many delicate pins in em that can be messed up and they’re all mounted on a little plastic tongue. One of those ground connections gets folded over and shorted to a power line and at best the controller shuts down to save everybody.

Yeah I have multiple USB cables, some at 30w, and some at 140w. Get them mixed up all the time! More companies need to at least brand the wattage on the connectors.

This is the big issue I have with with “USB C”. USB c is just the connector which can be used for so many things. What actual is supported depends on things you can’t see, like the cable construction or what the device supports.

There’s some really high bandwidth stuff that USB-C isn’t rated for. You have to really press the limits, though. Something like 4k + 240Hz + HDR.

That doesn’t even seem so unreasonable. Is that the limit though? My cable puts a gigabyte a second down it so I wouldn’t imagine that would hit the limit.
