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

Have you looked at the naming of the usb standards? No you havn't otherwise you wouldn't make this sensible suggestion.

[–] strawberry@kbin.run 6 points 8 months ago (1 children)

the shenenigans with USB 3 naming you mean? you're right, this would be too logical for USB lol

[–] Flipper@feddit.de 2 points 8 months ago (1 children)

Don't worry, they made it worse with usb 4.

[–] strawberry@kbin.run 1 points 8 months ago (1 children)

oh they did? how so?

USB 3.2 2x2 with 20 Gbps is the same as USB 4 Gen 2×2 with 20 Gbps

USB 4 Gen3x2 has 40 Gbps and was then renamed to USB 4 1.0
