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

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.

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.

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.
-
Today I learned DidplayPort 2.1 can carry 240W.
That's a lot of power! Are there even any devices that use this?
-
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‽
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.

Imagine putting out a new high bandwidth cable standard in 2025 based on copper

Passing power through doesn’t have to put noticeable load on the GPU.
I specifically said thermal load. Power delivery always causes heat dissipation due to I^2^R losses.

~~Why is that better than usb-c? ~~
Wait... Power the other way. Whoops, I get it.

That's what I meant. Compared to the power the GPU is actually using, transmission losses for a pass-through should be negligible. If you have a good way to get it to the card in the first place.

We already have alternative, it’s called thunderbolt port.

It can also do 120Gbps/40Gbps asymmetric.

Yeah, considering the recent VGA power connectors problems, what could possibly go wrong?

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.

noo we need yet another standard!
