Adjusting signal settings for a display using a light sensor

A non-transitory computer-readable medium including one or more sequences of instructions stored thereon that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• initiating calibration of an output signal of a media device, the media device providing the output signal to a display device;
• sending, by a mobile device, a message to the media device to begin a presentation on the display device;
• detecting, using a light sensor of the mobile device, properties of light emitted by the display device during the presentation to obtain sensor values related to the light emitted by the display device;
• and
• sending, by the mobile device, the sensor values to the media device, wherein the media device adjusts the output signal based on the sensor values.
