How to enable an extended DisplayLink display on macOS 10.13.4-10.13.6 with 4.3

This article applies to macOS 10.13.4-10.13.6 with 4.3 release from DisplayLink. This release supports one extended display using Apple AirPlay.

To setup the DisplayLink driver to use AirPlay:
  1. Install the latest 4.3.1 from our download page.
  2. You might need to enable video functionality - see more information here.
  3. Restart your computer and login.
  4. Make sure that “Show mirroring options in the menu bar when available” is checked in Display preferences.
  5. Accept the DisplayLinkUserAgent accessibility dialogue box which opens System Preferences -> Security&Privacy -> Privacy -> Accessibility. For help with this, or if this dialog does not appear, see this article.
  6. Allow DisplayLinkUserAgent application to control your computer.
  7. Connect your DisplayLink enabled device.
  8. You should now see the Airplay icon in your systems tray.
  9. Click "Use as Separate Display" to switch to extended desktop mode.

In Display preferences you need to have “Show mirroring options in the menu bar when available” checkbox ticked. This is requirement for automated AirPlay enabling when using accessibility, without this Airplay Icon in your systems tray does not show up.

To change the resolution of the extended display, click on DisplayLink icon on the System Tray and choose one of the available resolutions.


The following limitations exist with this solution:

  • AirPlay does not support rotation. It will not be possible to rotate any display with this solution.
  • Clam shell mode (lid closed) does not work and the desktop will go to sleep.
  • If you have multiple DisplayLink displays connected, there is no interface to choose which display becomes your Airplay display. If the wrong display is selected, then disconnect this display to prevent it being the AirPlay display.
  • On systems with non-standard firewall settings, firewall might require to allow incoming network connections for “DisplayLinkAirPlayBridge” application. 

If you experience no audio on macOS 10.13.4 – 10.13.6 with DisplayLink docking station then please make sure that DisplayLink USB device is set.
There is also DisplayLink AirPlay device available but this one is not working correctly with and USB audio device should be set.
