Displayport is an open standard in name only. The specs require membership in VESA, something that requires a hefty sum of money. Even open-source projects have to restrict code that implements Displayport because of the licensing restrictions imposed on the “open” standard.

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 4 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 4 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.
BombOmOm@lemmy.world 4 weeks ago
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.

In wall power cables need to be rated for it to prevent fire risks. This will need to have thick insulation or be made of a fire resistant material.

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.

I specifically said thermal load. Power delivery always causes heat dissipation due to I^2^R losses.
DuskyRo@lemmy.world 4 weeks ago
Nah, it’s for powering the 1000w RTX 6090.
PeachMan@lemmy.world 4 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.
jaxxed@lemmy.ml 4 weeks ago
Why is that better than usb-c?
Sizing2673@lemmy.world 4 weeks ago
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.
kayzeekayzee@lemmy.blahaj.zone 4 weeks ago
That’s a lot of power! Are there even any devices that use this?
sugar_in_your_tea@sh.itjust.works 4 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.
Blackmist@feddit.uk 4 weeks ago
Monitors, although I’m not sure I want my PC PSU powering those as well as everything else.
kkj@lemmy.dbzer0.com 4 weeks ago
They fixed it.
Funwayguy@lemmy.world 4 weeks ago
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.
YiddishMcSquidish@lemmy.today 4 weeks ago
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‽
SmoothLiquidation@lemmy.world 4 weeks ago
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.
ShinkanTrain@lemmy.ml 4 weeks ago
Bigass showroom screens I suppose?
FiskFisk33@startrek.website 4 weeks ago
its super nice to plug a laptop into a screen and have the cable double as a charging cable for the laptop
amorpheus@lemmy.world 4 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.
null_dot@lemmy.dbzer0.com 4 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.

Loved automobiles with 4 wheels? Chinese cars have 13! In your face suckers!
UltraBlack@lemmy.world 4 weeks ago
Not really that impressive since it seems to be about four times as wide as USB-C
princessnorah@lemmy.blahaj.zone 4 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 4 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 4 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 4 weeks ago
Your research would be incorrect
pennomi@lemmy.world 4 weeks ago
Yeah it was a quick google search. Do you have better numbers available?
IllNess@infosec.pub 4 weeks ago
Now you can use one cable for two 80".
Burghler@sh.itjust.works 4 weeks ago
Won’t this heat up like a mother fucker
avidamoeba@lemmy.ca 4 weeks ago
It depends on the voltage used. If they run 48V which seems to be supported by USB EPR. Then the cable has to do the same 5A it’s capable of doing today. Then the heat is the same.
Reverendender@sh.itjust.works 4 weeks ago
If it’s physically more stable and reliable than HDMI, then count me in
vane@lemmy.world 4 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 4 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 4 weeks ago
The whole point of USB-C is that it’s a standardised connector that allows anyone to shoehorn their own protocol down it if they want using Alt Mode. Moreover, they can do that without breaking compatibility with other USB-C - or even just specific features - if one of the devices doesn’t speak their crazy-ass moon protocols. This is a benefit of USB-C, not a failing.
vane@lemmy.world 4 weeks ago
Don’t get so excited. Read my comment again.
rmuk@feddit.uk 4 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] chanre all out things using a single connector, reducing e-waste, and, uh, ensuring there’s lots of futureproofing built-in. BASTARDS.
TheGrandNagus@lemmy.world 4 weeks ago
Please don’t make stuff up.
Other stuff isn’t banned and the law already has allowances for emerging standards.
MDCCCLV@lemmy.ca 4 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.
ceiphas@lemmy.world 4 weeks ago
Where I work, everyone has 2 4k screens. You can use two cables to connect them, you know…
And every one of them has either put their scaling up to 150% or simply set them to 2k, because you cannot read a damn thing on them.
More than 4k is a theoretical need for a veeeery small market
NeonKnight52@lemmy.ca 4 weeks ago
Actually? I don’t know much about that legislation. Does it really not have room built-in for tech improvements?
Estebiu@lemmy.dbzer0.com 4 weeks ago
It does! If there’s a good alternative it can be proposed, or that’s what I read here on Lemmy
Montreal_Metro@lemmy.ca 4 weeks ago
We already have alternative, it’s called thunderbolt port.
superniceperson@sh.itjust.works 4 weeks ago
No, we don’t. Apple proprietary nonsense isn’t worth the metal it’s made of.
bilb@lem.monster 4 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 4 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.
