To use Presentation Prompter with 3 or more screens the way you intend, you may need to set the display order. A typical scenario is wanting Screen 2 flipped for the talent and wanting Screen 3 to reflect the operator's unflipped script.

Instruction to set the display order:

  1. Disconnect all displays except the primary display. System Settings : Displays should only show your MacBook display (or a single display connected to a Desktop Mac).
  2. Connect the display you want to flip. In Presentation Prompter : Preview turn on Use second display and any flip options.
  3. Connect the display you want to mirror. In System Settings : Displays select the third display, then choose Use as Mirror for Built-in Display from the pop up*.

Sidecar and Airplay devices typically get their display order adjusted by macOS to come after physically connected monitors, even if they are connected before them. It may not be possible to designate these devices as Presentation Prompter's second display. These devices might be relegated to being used as a mirror for a built-in display in System Settings : Displays when using a physically connected monitor.


*Older macOS releases handle mirroring specific displays differently. To mirror specific displays on older macOS releases: In System Preferences : Displays, choose the Arrange tab, hold the Option key, then drag-and-drop the desired display box over the main display box (or whichever you wish to mirror). Holding the Option key while performing drag-and-drop is key to make it mirror two specific displays.
