    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‽

      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.

        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.

        GPU power connectors run at very very low voltages - just 12V. And you need to have ridiculously beefy connectors and wires to run high loads at 12V. At 48V you can have 4x more power with the same wire (if insulation is rated for 48V).

      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.
