A video graphics array (VGA) cable is a type of computer cable that carries visual display data from the CPU to the monitor. A complete VGA cable consists of a cable and a connector at each end, and the connectors are typically blue. A VGA cable usually has a screw on either side of the plug to mount it to the matching plug on the back of a computer system. The inside of the plug has pins that fit into the pattern of holes in the back of the computer. A VGA cable is used to connect your computer to your computer monitor.
