An image screen automatic adjustment apparatus for a video display monitor device is provided. The apparatus includes a microprocessor for handling the operation of the monitor device and for implementing the image screen adjustments. The monitor device has a switch for enabling the image screen automatic adjustment. Push button processor circuitry is coupled between the switch and the microprocessor for signalling to the microprocessor when the switch is enabled. Image inspection circuitry is coupled to the microprocessor for outputting horizontal and vertical image signals and horizontal front-back porch signals. When the image screen automatic adjustment switch is enabled, the image inspection circuitry provides the horizontal and vertical image signals and the horizontal front-back porch signals to the microprocessor for implementing an optimization analysis processing to obtain a set of optimized control parameters including a vertical size parameter V.sub.size, a vertical position parameter V.sub.position, a horizontal size parameter H.sub.size, and a horizontal position parameter H.sub.position. The microprocessor automatically adjusts the image screen based on this set of optimized control parameter.
