To quote the article:
a Type-B that seems to have a proprietary connector and a Type-C that is compatible with the USB-C standard.
So its half proprietary. No thanks!
Half-owned by a Chinese company is wholly owned by the CCP
Most important question
Why not use the already open displayPort and make it better.
noo we need yet another standard!
This was exactly what I wanted to post... 😅
Lock-in.
Displayport is an open standard in name only. The specs require membership in VESA, something that requires a hefty sum of money. Even open-source projects have to restrict code that implements Displayport because of the licensing restrictions imposed on the "open" standard.
This must be for commercial displays where it is beneficial for installation to have power and data over a single cable.
I can't think why I would want power delivery to my PC monitor over the display cable. It would just put extra thermal load on the GPU.
I think it's aimed at TVs in general, not computer monitors. Many people mount their TVs to the wall, and having a single cable to run hidden in the wall would be awesome.
I wonder what the use case is for 480W though. Gigantic 80" screens generally draw something like 120W. If you're going bigger than that, I would think the mounting/installation would require enough hardware and labor that running out a normal outlet/receptacle would be trivial.
Most OLED HDR TVs peak at over 300W.
Gigantic 80" screens generally draw something like 120W
In HDR mode they can draw a lot more than that for short peaks

Headroom and safety factor. Current screens may draw 120w, but future screens may draw more, and it is much better to be drawing well under the max rated power.

Nah, it's for powering the 1000w RTX 6090.
The popular use for power delivery through a display cable is charging a laptop from your monitor; it's already very common with Thunderbolt or USB-4 monitors. But 480W seems a bit overkill for that.
It would just put extra thermal load on the GPU.
Passing power through doesn't have to put noticeable load on the GPU. The main problem I see there is getting even more power to the GPU - Nvidia's top cards are already at the melting point for their power connector.

Today I learned DidplayPort 2.1 can carry 240W.
That's a lot of power! Are there even any devices that use this?
Monitors, although I'm not sure I want my PC PSU powering those as well as everything else.
PCs can use >1KW.
I don't know why you'd power a PC over DisplayPort though. New 8k monitors do go up to 190W, so we could exceed 240W if we try hard enough.

Running that much power next to a data line sounds like a terrible idea for signal integrity, especially if something shorts to said data lines. It just sounds sketchy or filled with so many asterisks that it's functional impossible to reach their claimed throughput.
It's likely dc current which without the alternating magnetic fields will not degrade the signal as bad. But I whole heartedly agree with you on power delivery. What could possibly need/use that much power‽
The option to run one cable to the monitor, or reversely charge your laptop with one docking cable.
Maybe you could use this to daisy chain monitors and power them all.

Loved automobiles with 4 wheels? Chinese cars have 13! In your face suckers!
Imagine putting out a new high bandwidth cable standard in 2025 based on copper.
The sooner display and networking move to SFP, the better.

Not really that impressive since it seems to be about four times as wide as USB-C
So is HDMI? Smaller connectors aren't always better, and it's not like it's SCART size or something.
Even an 80” tv only uses around 150W, if my research is correct. Surely this must be thinking about massive displays.
If you’re gonna release a new standard, may as well have the headroom for future growth so it’s not outdated too soon in the future.

If it’s physically more stable and reliable than HDMI, then count me in
