Many television sets are equipped with three jacks for transmitting a video signal through component cables. Known as RGB video cables, the designation comes from the colours on the plugs: red, green and blue. Setting up a TV with RGB jacks to connect with a laptop requires an adaptor to convert the three separate signals into a Video Graphics Array plug. The VGA plug contains 15 pins in three rows to connect with the holes in the VGA jack.
