Issue: I recently updated my macOS (or got a new Mac) and now my external monitors display a black screen. I am using a Dell DisplayLink docking station to connect my Mac to the monitors.
Environment: University-owned Mac, Dell DisplayLink docking station, external monitors
Resolution: Open Macintosh HD | Applications and run DisplayLink Manager. If it is not present or not working, proceeding with the following steps...
- Open the Self Service application
- Locate Displaylink Manager or Displaylink and select the Install button
- Once Displaylink Manager or Displaylink has successfully installed, launch it as you would an app
- Displaylink Manager or Displaylink should automatically ask for screen recording permission. If not, you can allow this permission manually:
- Open System Preferences
- Select Security & Privacy
- Go to Privacy
- Scroll down the menu and select Screen Recording
- Check the Displaylink Manager or Displaylink box
- A dialog box appears asking you to either select "Later" or "Quit Now". Select Later.
The monitors should now be displaying correctly.
