Image screen automatic adjustment apparatus for video monitor

An image screen automatic adjustment apparatus for a video display monitor device comprising:

• a microprocessor means for handling the operation of said monitor device and for implementing said image screen adjustment;
• and image screen automatic adjustment enable switch means provided on said monitor device;
• a push button processor circuitry coupled between said image screen automatic adjustment enable switch means and said microprocessor means, said push button processor circuitry signalling to said microprocessor means when said enable switch means is enabled;
• and
• and image inspection circuitry coupled to said microprocessor means, the image inspection circuitry for outputting horizontal and vertical image signals and horizontal front-back porch signals;
• wherein when said image screen automatic adjustment enable switch means is enabled, said image inspection circuitry provides the horizontal and vertical image signals and said horizontal front-back porch signals to said microprocessor means 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, and said microprocessor means automatically adjusts said image screen based on said set of optimized control parameters.
