An automatic precision video monitor alignment and calibration system is described which functions to precisely align all of the adjustable display characteristics of a video monitor to a high degree of precision. This alignment system can function in an automated calibration mode wherein it is independent of human input and automatically performs a series of alignment/calibration operations to precisely adjust all of the display characteristics of the video monitor in a fraction of the time required by a person to manually align the video monitor. The alignment system includes a digital control circuit located within the video monitor to precisely set and maintain each of the monitor display characteristics. The values maintained by this control circuit can be input by a person, or set automatically by a computer controlled display alignment system. The system of the present invention uses a single camera and a color analyzer to make all the measurements necessary to automatically align and calibrate a video monitor. The measurements are then used to make the adjustments, via the digital control circuit, necessary for alignment and/or calibration. A calibration computer coupled with a video coprocessor subsystem accomplish all adjustments to the monitor automatically, without the need for human intervention.
