We worked with Farouk via our email ticketing system on this issue. A clean installation of the drivers resolved the issue.

The steps for this process are:

-Disconnect the USB adapter from the computer

-Uninstall DisplayLink Core software from Control Panel->Programs

-Download and run the DisplayLink cleaner tool, found here:…

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

-Now download and run the latest DisplayLink software, found here:…

-Reboot, even if not prompted to

-Once you’re back in Windows, reattach the adapter which should trigger the final phase of the installation
