Using a second display as a teleprompter is called dual-screen prompting. To control whether Presentation Prompter uses one or two displays:

  1. Show the Preview window if it is not already displayed by choosing Window ‣ Preview ⌥⌘P.
  2. Click the “Use second display” checkbox to turn dual-screen features on or off.

If “Use second display” and the options below it are disabled or highlighted, the bottom of the Preview window tells you why (e.g., “second display is not connected”). If the problem can be fixed with a display configuration change, a button will be provided to do so. More about this.

When “Use second display” is turned on what you see in the Preview window is what the talent sees.

Hide edits from talent / Blank out edits

By default, editing changes track along on the second display. If you want to hide your edits or are requested to "blank out" the second screen, you can do so by turning on the “Hide edits from talent” checkbox.

The default image that shows up says "Standby", but this can be changed to a blank screen, or even a custom image with your production unit's logo, if desired. You can make these changes by using the the arrow menu located next to the checkbox.

Text flipping

Text flipping flips content either horizontally or vertically on the talent screen for use with a mirror enclosure.

Example of horizontal flipping:

Operator window example Talent window example
Operator screen Talent screen

Example of vertical flipping:

Operator screen Talent screen

To use text flipping:

  1. Ensure “Use second display” is turned on as described above.
  2. Turn horizontal text flipping on or off by clicking the “Flip horizontally” checkbox in the Preview window.

  3. Turn vertical text flipping on or off by clicking the “Flip vertically” checkbox in the Preview window.

When any text flipping options are used, the Preview window continues to display an unflipped preview so you can follow along with the talent in Edit mode.

Video mirroring

If you need dual-screen prompting but do not need to use text flipping, you can video mirroring in macOS for even more performance. See how to set extended desktop or video mirroring for more information.
