Abstract
A system may include multiple electronic devices. A first device such as a source electronic device may supply visual content for displaying by a display in a second electronic device such as a display electronic device. The display electronic device may be a television or other device with a display. Calibration operations may be performed by taking light measurements on light produced by the display when test content is provided from the first device to the second device. A third electronic device in the system such as a portable electronic device with an ambient light sensor may make measurement on the light from the display while the test content is being displayed. The test content may contain a test image target with time-varying color and time-varying intensity, allowing calibration information such as gamma curves to be obtained on the display.
