description The invention relates to a multi-test instrument integrated display audio automatic test system and method. The system comprises a computer, a video signal generator, an audio analyzer, a DDCCI control circuit, a low-pass filter, an aluminum shell resistor and a display to be tested, and the computer is connected with the video signal generator through an RS232-to-USB line; the computer is connected with the DDC/CI control circuit through a USB-typeB interface, the computer is connected with the audio analyzer through an APIB audio special interface, the DDC/CI control circuit is connected with a display to be tested, the two ends of the aluminum shell resistor are connected with a loudspeaker power amplifier interface of the display to be tested through a 4Pin interface, and the aluminum shell resistor is connected with the low-pass filter through an RCA interface; and the low-pass filter accesses the noise-filtered signal to the audio analyzer through the cannon port. The system and the method are high in a
