When a Plugable DisplayLink device is not working as expected with a Mac system, the best practice is to disconnect the device from the host system (and remove its external power source, if it has one) and then perform a 'clean' manual installation of the latest version we recommend of the required DisplayLink software in order to help ensure both are in a good state.
To do so, please follow these steps:
1) Disconnect the Plugable USB docking station or video adapter from the host system.
If the product you are using has an external power adapter (for example, a USB docking station), please also disconnect the power adapter from the product so that the unit resets. Please keep everything disconnected until prompted
2) Run the DisplayLink macOS Installation Cleaner
Please download and run the DisplayLink macOS Installation Cleaner utility --> LINK
Should you need them, there are detailed instructions for using this utility available here --> LINK
3) Reboot your Mac
Once the DisplayLink macOS Installation Cleaner utility has been run, please reboot your Mac (even if not prompted).
4) Install latest recommended version of the DisplayLink software
Now download and install the latest version of DisplayLink Manager Application that we recommend for your version of macOS → LINK
Should you need them, detailed installation instructions are available by clicking on the ‘INFO’ button next to the download.
5) Reconnect power (if applicable) and reconnect the product to your Mac
If you disconnected the power adapter from your product in step one, please reconnect it so the device powers on, then reconnect the product to your Mac. If the product is still not working as expected, please restart the Mac one more time.
If after having completed this process your Plugable DisplayLink device is still not working as expected, please reach out to us directly via support@plugable.com with the output of our PlugDebug diagnostic utility (LINK) and we will be happy to assist you further.
