Hi again,
I was puzzled so looked deeper.
http://targus.com/au/usb-c-1k-4k-dua...specifications
The product page for the Dock 410 states this is USB alt-mode.
--> DisplayPort, HDMI and DVI-D ports (up to 3840x2160) via USB-C alternate mode native video
This is not USB. This is not using DisplayLink technology.
Kind regards,
Alban
