The current display link drivers has issues on MacOS 10.12 Sierra. Black screens waking from sleep and graphic Errors
When my computer wakes from sleep, all of my screens will stay black until I unplug the dock. I also see a lot of graphic errors on the secondary display and the computer freezes a lot when I'm working on the secondary display. Not only is the dock causing my secondary display to not work, it is causing my computer to become unstable trying to correct it.
This is a major issue I've been fighting to fix. Please get a new driver to resolve the display issues in 10.12.4.
