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!

Half-owned by a Chinese company is wholly owned by the CCP

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.

[-] IrateAnteater@sh.itjust.works 49 points 2 weeks ago

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.

[-] GamingChairModel@lemmy.world 13 points 2 weeks ago

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

[-] Cocodapuf@lemmy.world 6 points 2 weeks ago

My 50" 1080p LCD draws over 200w...

[-] IrateAnteater@sh.itjust.works 14 points 2 weeks ago

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.

Nah, it's for powering the 1000w RTX 6090.

[-] PeachMan@lemmy.world 8 points 2 weeks ago

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.

[-] amorpheus@lemmy.world 7 points 2 weeks ago

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.

[-] drspod@lemmy.ml 7 points 2 weeks ago

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.

Thought of this too, with the addition "so we can control that market".

[-] ShinkanTrain@lemmy.ml 51 points 2 weeks ago

Today I learned DidplayPort 2.1 can carry 240W.

[-] kayzeekayzee 17 points 2 weeks ago

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

[-] sugar_in_your_tea@sh.itjust.works 18 points 2 weeks ago

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.

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.

[-] null_dot@lemmy.dbzer0.com 5 points 2 weeks ago

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.

[-] amorpheus@lemmy.world 5 points 2 weeks ago

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.

[-] kkj@lemmy.dbzer0.com 7 points 2 weeks ago

USB4v2 can do 80Gbps and 240W.

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

The sooner display and networking move to SFP, the better.

[-] cmhe@lemmy.world 6 points 2 weeks ago

SFP? You mean the every device has slots to plug in different transceiver modules? I guess that would make it more future proof, but I think that will raise the cost, and might confuse ordinary people.

You have to think about the slot-transceiver compatibility and transceiver-medium compatibility then. Hmm... but I guess that would make it more transparent what is going on than having those chips embedded inside the cables, but not sure if we can leave them out, and require the end users to take care of thinking of all these compatibilities themselves or risk fire hazards.

Not really that impressive since it seems to be about four times as wide as USB-C

[-] princessnorah 18 points 2 weeks ago

So is HDMI? Smaller connectors aren't always better, and it's not like it's SCART size or something.

[-] pennomi@lemmy.world 17 points 2 weeks ago

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

[-] cannedtuna@lemmy.world 28 points 2 weeks ago

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.

[-] Anivia@feddit.org 10 points 2 weeks ago

Your research would be incorrect

[-] pennomi@lemmy.world 4 points 2 weeks ago

Yeah it was a quick google search. Do you have better numbers available?

[-] Anivia@feddit.org 11 points 2 weeks ago

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

Now you can use one cable for two 80".

Won't this heat up like a mother fucker

[-] avidamoeba@lemmy.ca 7 points 2 weeks ago* (last edited 2 weeks ago)

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

When it comes to their own new connector/cable they can use even higher voltage or more/thicker conductors for power.

[-] Reverendender@sh.itjust.works 12 points 2 weeks ago

If it’s physically more stable and reliable than HDMI, then count me in

[-] Montreal_Metro@lemmy.ca 8 points 2 weeks ago

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

[-] superniceperson@sh.itjust.works 16 points 2 weeks ago

No, we don't. Apple proprietary nonsense isn't worth the metal it's made of.

[-] bilb@lem.monster 8 points 2 weeks ago

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.

[-] humanspiral@lemmy.ca 6 points 2 weeks ago

Power delivery by itself could be a useful standard for ebike and power station charging (battery to battery charging too). 480w is most I've seen, but maybe USB is working on better, or 240w and more flexible/cheaper cables can work. HDMI providing 54v output would be great for most common battery system charging, and dual/triple BMSs for 2x and 3x ports/charging would be awesome.

[-] vane@lemmy.world 4 points 2 weeks ago

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

[-] null_dot@lemmy.dbzer0.com 14 points 2 weeks ago

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.

[-] rmuk@feddit.uk 10 points 2 weeks ago* (last edited 2 weeks ago)

In case anyone is wondering, yes, this is utter nonsense. The EU made USB-C mandatory only as a charger for portable devices like phones, tablets, headphones and mice. That's all. This new standard, unwelcome as it is, has nothing to do with charging phones so there's no reason why it can't be used in the EU.

But let's not allow measley facts get in the way of having a moan at nothing, shall we? Fucking EU. Forcing us to [checks notes] charge all out things using a single connector, reducing e-waste, and, uh, ensuring there's lots of futureproofing built-in. BASTARDS.

[-] MDCCCLV@lemmy.ca 4 points 2 weeks ago

I think you could have a second connector in addition to a main USBC.

Honestly we need higher capacity for screen cables for PC. Both HDMI and display port are limiting performance because of their low, 40-80gbps, bandwidth. Their performance maxes out at 4k120hz with uncompressed HDR color. You can't use 8k screens or multiple 4k screens without lowering quality.
