Is it an open standard?

Even an 80” tv only uses around 150W, if my research is correct. Surely this must be thinking about massive displays.

Won't this heat up like a mother fucker

If you’re gonna release a new standard, may as well have the headroom for future growth so it’s not outdated too soon in the future.

Now you can use one cable for two 80".

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.
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.

Is it an open standard?
Most important question
-
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.
Even in that scenario it will complicate the setup. Now your Roku will also have to also power your TV? No, any sane setup will have a separate power cable for the TV.

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.

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.

In wall power cables need to be rated for it to prevent fire risks. This will need to have thick insulation or be made of a fire resistant material.

It depends on the voltage used. If they run 48V which seems to be supported by USB EPR. Then the cable has to do the same 5A it's capable of doing today. Then the heat is the same.

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.

In HDR mode they can draw a lot more than that for short peaks

Bigass showroom screens I suppose?

That already kinda allow this and the actual load is pretty small
Even a big 30 in display is maybe 20 watts
Well, power delivery goes several times that. Laptops are another very useful case for it. It's nice to be able to just have a single display port and power connector
You can do this to an extent, today

Today I learned DidplayPort 2.1 can carry 240W.
