China launches HDMI and DisplayPort alternative — GPMI boasts up to 192 Gbps bandwidth, 480W power delivery
-
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‽
Yeah, considering the recent VGA power connectors problems, what could possibly go wrong?
-
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.

Why not use the already open displayPort and make it better.
noo we need yet another 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.

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.

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

Actually? I don't know much about that legislation. Does it really not have room built-in for tech improvements?
It does! If there's a good alternative it can be proposed, or that's what I read here on Lemmy

the GPMI cable comes in two flavors — a Type-B that seems to have a proprietary connector and a Type-C that is compatible with the USB-C standard
I actually copied this from the article to come here to the comments and have a whinge about all the different USB-C standards, and here you are explaining the reason why.

So if you have a beefy psu you should be able to power your monitor off tbe DP?
Or does carrying power limit data throughput?
-
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.

Don't get so excited. Read my comment again.

It might? I think USB uses data lanes for power delivery above some point, and I wouldn't be surprised if DP does the same.

Hi! I actually work at a major electrical connector company, so maybe I can shed some light on this.
I have no idea.

I used to work with electrical engineers, and whenever I asked about details, they'd shrug and say, "black magic?" Checks out.

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...

Based on this pin configuration, there's only two dedicated power pins, which isn't very good for large wattages. The rest are twinax signal pairs separated by ground to reduce crosstalk.Usually when connectors are designed for power delivery, they'll use bigger contacts to reduce the contact resistance (signal contacts tend to be small so you can fit more of them in the same space). I'm guessing the original DP connector form factor wasn't made with such high power in mind, so it would make a lot of sense to use the spare signal pins for power delivery in this case. Running too much power through too few small pins can damage the contacts, by either by instant-welding the contact surfaces or by overheating the connector (see NVIDIA GPUs) ((also high voltages can cause arcing, which even in the best case will seriously degrade any connector)).
Take all of this with a huge grain of salt cause I just learned this stuff like a month ago, and my department has nothing to do with any of it. Just though someone might find it interesting.
