ABSTRACT:
A portable, universal video and audio computer tester has a video section including a pluggable video connector for connecting to an external source of a video signal; a video detector for detecting an input RGB video signal; a video indicator for signaling presence of an input RGB video signal; a synch detector for detecting an input video synchronization signal; and, synch indicating means for signaling presence of a and input horizontal and a vertical synchronization signal. An audio section has pluggable audio connectors; an internal audio generator for creating an output audio signal; an audio indicator for signaling presence of an input audio signal from the external source or from the internal audio generator; a switch for changing an operational mode from an input audio signal to an output audio signal. Connection to either an external or internal power supply is provided. Operations of video computer interfaces and audio computer interfaces can be verified by connection to the video connector and to the audio connector, respectively.
