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

They fixed it.
-
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.
USB4v2 can do 80Gbps and 240W.

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.
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.

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.
~~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.

USB4v2 can do 80Gbps and 240W.
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.
-
Why not use the already open displayPort and make it better.
noo we need yet another standard!
-
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!

Lock-in.

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.

If it's not usb-c it's banned in EU. Because we stopped there and we won't go forward.
