Definition - What does VGA Cable mean? 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 is used primarily to link a computer to a display device. One end of the VGA cable is attached to the port in the graphics card on the computer motherboard, and the other to the port in the display device. When the computer is running, the video card transmits video display signals via the VGA cable, which are then displayed on the display device.
Difference Between VGA and DVI. Video Graphics Array or VGA and Digital Video Interface or DVI are the two methods of connecting your monitor into your computer. The main difference between these two is that VGA is an analog standard while DVI is digital. DVI is next logical step for connecting your computer and monitor. Video signals are originally digital signals but are converted into analog before leaving the GPU of your computer through the VGA port. VGA was created because all of the monitors at that time are based on CRTs which were analog in nature.
