Hello RSBoston,

Thanks for reaching out to us on our forums! Based on the description of the problem, it sounds like we should start with what we call a ‘clean’ installation of the DisplayLink drivers that power the docking station. This is a little different than I typical uninstall and reinstall, as we’ll use a special tool to completely remove any traces of the drivers before installing the latest version anew. Steps on this are below:

DisplayLink Clean Install Steps

  1. Disconnect the dock from the system and please remove the power cable from the dock so it turns off completely (this is important so the unit resets). Please keep it disconnected until the last step.

  2. 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

  3. Download, extract and run the DisplayLink cleaner tool, found at this link below:…

  4. After running the cleaner tool, ensure it displays “Cleaning Complete” when done.

  5. Once the Cleaner has been run, reboot (even if not prompted to)

  6. Now download and install the 8.4 M0 DisplayLink software, found here:…

  7. 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 click the ‘Skip’ button to allow the process to complete and then reboot the system.

I hope these steps help, but if not we’ll continue looking into the issue. Let me know if you have any questions, and I look forward to working with you on this issue!

Patrick - thank you for the reply - I followed the directions you laid out and it cleared the error. I now have the desk monitor showing clearly via the Plugable 3.0 HDMI link.
