Thank you for contacting Plugable support! I’d be more than happy to assist you with this issue.
I suggest a clean installation of the newest drivers:
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 the DisplayLink Core software from the Control Panel -> Programs and Features. Don’t worry if this fails, just move onto the next step
Download, extract and run the DisplayLink cleaner tool, found here --> http://www.displaylink.com/downloads/… 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 8.1 M0 DisplayLink software, found here --> http://www.displaylink.com/downloads/…
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 fails we have a troubleshooting tool that helps us find out what is going on in situations like this. Please plug the dock into your computer, then go to this page and follow the instructions there:
Please don’t hesitate to let us know of other questions.
Thanks again for contacting Plugable support and best wishes!
