The HDMI Forum rejected AMD's open source HDMI 2.1 implementation - tchncs

Sounds like hdmi Forum are a bunch of twats. Time for a new format.
DisplayPort already exists
And also USB c
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?
Please think of the shareholders… :(
Have you looked at the naming of the usb standards? No you havn’t otherwise you wouldn’t make this sensible suggestion.
the shenenigans with USB 3 naming you mean? you're right, this would be too logical for USB lol
Don’t worry, they made it worse with usb 4.
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

jesus what the fuck
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.
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.
It is trivial arithmetic: 4.52403840*2160 ≈ 9 GB/ s. Not even close. Even worse, that cable will struggle to get ordinary 60hz 4k delivered.
I think the maths got a bit funky there. I don’t think a cable capable of such speeds would struggled to do 60Hz at 4K, it surely doesn’t need close to a gigabyte a second?
It surely does. Check pirates post for clean math formatting

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.
