Abstract
A method for setting an output of a projector of a display system, is provided. The method includes displaying an image on a projector screen using the projector, measuring a light characteristic emanating from the projector screen using a first meter on a first side of the projector screen, adjusting the output of the projector until a desired value of the light characteristic is measured at the first meter, measuring the light characteristic of light emitted from the projector, with a second meter on a second side of the projector screen, to obtain a light characteristic measurement that corresponds to the desired value, and storing the light characteristic measurement that corresponds to the desired value.
