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

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

For macOS 10.14 onwards, v5.x or later software should be used, which restores multiple extended display support, without needing to use 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.
