Sorry to hear about this issue. That’s quite odd! I’d be more than happy to assist you.
I’d suggest that we proactively reload the latest version of the DisplayLink drivers which control the two DP video outputs, audio, and the Ethernet. Here’s how:
Disconnect the dock from the system and please remove the power cable from the dock so it turns off completely. Please keep it disconnected until the last step.
Uninstall any and all software with ‘DisplayLink’ in the title that is present from within the Control Panel -> Programs and Features. Don’t worry if these entries are not present or if the process does not work, just move onto the next step.
Download, extract and run the DisplayLink cleaner tool, found here --> http://www.displaylink.com/downloads/file?d=64 and ensure it displays “Cleaning Complete”
when done (video walk-through if you need it -> https://youtu.be/AcVV1gD_FvI)
Once the Cleaner has been run, reboot (even if not prompted to)
Now download and install the 9.3 M2 DisplayLink software, found here --> https://www.displaylink.com/downloads/file?id=1566
Reattach the power cable to the dock first. Once the dock is powered on, reconnect it to your system which will trigger the final portion of the installation. If the device is not detected, please reboot the system.
If that doesn’t help, let me know, we may need to collect some diagnostics to see what’s going on.
Please don’t hesitate to let us know of other questions.
Thanks again for contacting Plugable support and best wishes!
