I guess that points to a chance that a USB-C 5A cable at 20V or something could soon power something like this. If that cable were carrying the DP signal, that'd be rad.
I'm really struggling to wrap my mind around how sensibly pushing 100W of power out of a wee little USB-C port on a laptop might look though.

It could also be possible that faster displayport alternate modes could be possible, but are just not available on current-gen transceivers.
