I'll chime in here as well. I had just gotten the Dell D6000 USB dock to use with a couple of 2016 MacBook Pros (both 13 and 15-inch), and the DisplayLink Manager was not working for me consistently. There was a brief moment when I was setting it up and it somehow worked (i.e. allowed me to use it in clamshell mode successfully), but that was short-lived and stopped working when I switched computers and switched back.
After reading through these comments, the workaround that worked for me was:
1) Uninstall DisplayLink Manager and unplug the dock (not sure if unplugging is necessary, but you might as well do it)
2) Install the DisplayLink USB Graphics Software (version 5.2.5 for me, but 5.2.4 or 5.2.1 would have likely also worked as suggested by other users). I followed these directions (https://support.displaylink.com/knowledgebase/articles/1188004-macos-10-13-10-14-and-10-15-video-functionality) to allow the kernel extension.
3) Restart after installation, then plug in the dock.
Hope that ends up helping someone. I was getting pretty frustrated at having to have my laptop open when docked and finding this thread was a godsend.
