Abstract
In a projection display system, a sample of the light output may be extracted and used to calibrate the display. A sample may also be used in multi-display systems (e.g., light walls), wherein the information from one display in the form of a light sample may be shared with one or more additional displays. In this way, certain characteristics of multiple displays may be correlated with one another to produce a uniform display output.
