Is it an open standard?
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
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.
Gigantic 80" screens generally draw something like 120W
In HDR mode they can draw a lot more than that for short peaks
My 50" 1080p LCD draws over 200w...
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.

I specifically said thermal load. Power delivery always causes heat dissipation due to I^2^R losses.

Today I learned DidplayPort 2.1 can carry 240W.
That's a lot of power! Are there even any devices that use this?
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.
See, IDK anything about data and power and cables but I dislike the vibe when I dock my laptop with that itty bitty USB-C connector that does power and 2x monitors and networking and peripherals.
I did buy the bonkers expensive proper cable from lenovo, and it does generally just work, but maybe once every few weeks I have to unplug & re-plug.
More power and more data through the same cable just seems daft.
USB standard is up to what, 40Gbps and 240W? That's pushing the envelope already. We'll see if this new standard can prove itself, anyways.

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.
SFP? You mean the every device has slots to plug in different transceiver modules? I guess that would make it more future proof, but I think that will raise the cost, and might confuse ordinary people.
You have to think about the slot-transceiver compatibility and transceiver-medium compatibility then. Hmm... but I guess that would make it more transparent what is going on than having those chips embedded inside the cables, but not sure if we can leave them out, and require the end users to take care of thinking of all these compatibilities themselves or risk fire hazards.

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.
Your research would be incorrect
Yeah it was a quick google search. Do you have better numbers available?
Most manufacturers only list average power draw, but in HDR mode you can get much higher peak power useage.
This website also lists peak power draw for many TVs, in this example the Bravia 9 85 inch has a peak of 380W

Now you can use one cable for two 80".
If it’s physically more stable and reliable than HDMI, then count me in
Won't this heat up like a mother fucker
It depends on the voltage used. If they run 48V which seems to be supported by USB-C EPR. Then the cable has to do the same 5A it's capable of doing today. Then the heat is the same.
When it comes to their own new connector/cable they can use even higher voltage or more/thicker conductors for power.
We already have alternative, it’s called thunderbolt port.
No, we don't. Apple proprietary nonsense isn't worth the metal it's made of.
I usually associate it more with Intel since they certify Thunderbolt devices on all the non-Apple hardware and that's all I use. I forgot Apple had anything to do with it.
Power delivery by itself could be a useful standard for ebike and power station charging (battery to battery charging too). 480w is most I've seen, but maybe USB is working on better, or 240w and more flexible/cheaper cables can work. HDMI providing 54v output would be great for most common battery system charging, and dual/triple BMSs for 2x and 3x ports/charging would be awesome.
