This is a most excellent place for technology news and articles.
Loved automobiles with 4 wheels? Chinese cars have 13! In your face suckers!
Imagine putting out a new high bandwidth cable standard in 2025 based on copper.
The sooner display and networking move to SFP, the better.
Why not use the already open displayPort and make it better.
Lock-in.
Today I learned DidplayPort 2.1 can carry 240W.
They fixed it.
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.
USB4v2 can do 80Gbps and 240W.
It can also do 120Gbps/40Gbps asymmetric.
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?
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.
Bigass showroom screens I suppose? Maybe large sound systems?
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.
Won't this heat up like a mother fucker
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.
Even an 80” tv only uses around 150W, if my research is correct. Surely this must be thinking about massive displays.
Your research would be incorrect
Yeah it was a quick google search. Do you have better numbers available?
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
Now you can use one cable for two 80".
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.
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!
Most important question
If it’s physically more stable and reliable than HDMI, then count me in
