Upon undocking, the macs are regularly left with a "phantom" screen, which can't be disabled by toggling Detect Display etc. A restart of either the mac or displayLink driver clears this.

The display appears functional to the mac, with windows remaining on the disconnected display. Upon reconnection of the same display, N+1 displays exist, with both the connected display(s), and the phantom one left from the last docking.

If you have not done so already, I would suggest reporting the issue to DisplayLink directly by following the process outlined here --> https://support.displaylink.com/know...to-displaylink
