Use Projector Calibrator in macOS

Projector Calibrator helps you to project the best image for the lighting conditions in your room.

If you’re using a projector as an external display, you may need to adjust the projected image for the light conditions in your room. If the projected image isn't calibrated, parts of the image may seem too light or too dark, and colors may not appear as intended. In OS X Yosemite or later, Projector Calibrator helps you make these adjustments.

Open Projector Calibrator

Make sure that your projector is turned on and displaying your Mac desktop, then open Projector Calibrator:

  • Click the AirPlay icon   in the menu bar, then choose Open Projector Calibrator.
  • Or choose Apple menu > System Preferences, then click Displays. From the preferences window on the projected display, click the Color tab, then click the Projector button.

Adjust black level and white point

Projector Calibrator has two slider controls:

  1. The first slider is next to the dark circle. Drag the control up or down to adjust black level. Black level is calibrated when you see only one rotating circle inside the dark circle.
  2. The second slider is inside the multicolored ring. Drag the control in any direction to adjust white point. White point is calibrated when the white inside the ring is neutral or matches a white surface in the room.

If the light conditions in your room change, repeat these steps to recalibrate the projected image for the current ambient lighting.
