Hi Roger,
With two Windows PCs, then we expect this setup to work! You can see the following video which outlines this kind of setup: https://www.youtube.com/watch?v=dYy0tdMworg
Our USB 3.0 docks have an Ethernet port, so you should be able to toggle this Ethernet connection (along with displays, USB peripherals, etc.) assuming that the dock’s DisplayLink driver is installed on both systems.
I hope this helps!
