Abstract:
A printed circuit board comprises a substrate as well as resistors and electrical connections disposed on the substrate. The substrate couples to a video graphics array connector that has pins, including video pins and return pins. A video pin transmits a video signal, and a return pin provides a ground for a corresponding video pin. The substrate has openings, where each opening can receive a pin. The resistors and the electrical connections couple to a subset of the pins to mimic an external video graphics array monitor. The resistors comprise: a red connection resistor that can couple a red video pin with a red return pin; a green connection resistor that can couple a green video pin with a green return pin; and a blue connection resistor that can couple a blue video pin with a blue return pin.
