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?
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.

The way it works for power over Ethernet — and I assume USB power delivery must work the same way — is that it does not reduce bandwidth because they run the power and the signal over the same wires at the same time.
There is a a power injector at one end and a filter at the other end that separate out the high-frequency signal and the DC (no-frequency) power into different wires.
This is essentially the same thing as they’re already doing for multi-frequency stacking on those same wires (and on fiber) to get the crazy bandwidth in the first place. DC power is just one more low (very very low) frequency running on the same stack.

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.

A full PC, no, but a set top box definitely yes. And a set top box is plenty of computing power for a thin client, think workstations for accountants.

Is it bidirectional then, like USB-C?
barsoap@lemm.ee 11 months ago
Honestly, I have no idea.

Why accountants specifically?

Any complex data stuff they could need should be done on some database server, the rest of what they’re doing can be done by anything that can deal with minesweeper.
