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.
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
USB-C with Thunderbolt currently had a limit of 40Gbit/sec. Wikipedia has a table of what DisplayPort can do at that bandwidth:
en.wikipedia.org/wiki/DisplayPort
See the section “Resolution and refresh frequency limits”. The table there shows it’d be able to do 4k/144hz/10bpp just fine, but can’t keep above 60hz for 8k.
Its an uncompressed video signal, and that takes a lot of bandwidth. Though there is a simple lossless compression mode.
