ABSTRACT:
A display monitor capable of providing fully synchronized image display in response to an incoming video signal having a range of possible timing formats. The monitor employs a microprocessor that discriminates between the disparate horizontal and vertical sync signals by developing a characteristic signature of the timing format and thereafter searching a resident database of different formats to discern a match. A calibration mode is provided to allow the adjustment of the monitor to an incoming signal that is otherwise unrecognized by the microprocessor or to allow the updating of previously stored information.
