When starting up, an Apple Studio Display 17 may make a noise and the image may shimmer a bit before it settles down.

Products Affected

Displays

The display is behaving normally and does not require service. What is happening is called Degaussing. Degaussing is the process of stabilizing the magnetic field of the CRT. It is a normal function of every display and does not indicate a need for service.

Waking the display from sleep or initiating a degauss from the on-screen display can also cause the same noise to be generated.

The viewable image size of the Apple Studio Display 17 is 16.0 inches.
