ABSTRACT:
An exemplary video graphics array interface tester includes a VGA connector being configured to couple to a VGA interface to be tested and having a plurality of signal pins to output different VGA signals; a load circuit connected to the signal pins of the VGA connector for impedance matching; a selection switch having a plurality of throws corresponding to the signal pins of the VGA connector connected to the signal pins of the VGA connector respectively, and a pole; and a test port connected to the pole of the selection switch for selectively testing one of the VGA signals via selection of the selection switch. Using this tester to detect the VGA interface can guarantee quality and improve efficiency of VGA test.
