Gather Windows

If you are connecting your Mac to a second screen, like you may do before a presentation, you may get into a situation where the System Preferences, Displays controls can’t be altered on the second screen because the second screen is off or not working yet. Click the Gather Windows button to bring all the displays’ settings to your main screen so you can change them while that second screen is not visible.
