China launches HDMI and DisplayPort alternative — GPMI boasts up to 192 Gbps bandwidth, 480W power delivery

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.

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

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‽
Bigass showroom screens I suppose?

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.
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.

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

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 don't think you'd ever have a peripheral power the tv. The use case I'm envisioning is power and data going to the panel via this single connector from a base box that handles AC conversion, as well as input (from Roku etc) and output (to soundbar etc.). Basically standardizing what some displays are already doing with proprietary connectors.

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

Ah perfect, that makes a lot more sense to me

Why not use the already open displayPort and make it better.

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.
The option to run one cable to the monitor, or reversely charge your laptop with one docking cable.
USB-C docks can already do this. Obviously with less power and it's not perfect by any means, but we don't need another technology for this. And sure, it's two cables, one from wall outlet to integrated dock/monitor and usb-c from dock to laptop, but no matter the technology you still need something to plug in to wall outlet.

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.

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.
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.

That's a lot of power! Are there even any devices that use this?

Displayport and hdmi are either twisted pair or coaxial I think. Low frequency RF from 50hz AC shouldn't interfere with them, but high frequency changes in current on a power wire will.

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