VGA stands for Video Graphics Array. This was the graphics standard used by IBM in their early computers of 1980s. Today, majority of the computers support VGA and even more advanced system depending on the monitor used. The Windows loading screen that appears is by the use of VGA.
VGA cable is used to carry the display signals regardless of any graphic system being used. There are 15 pins in this cable arranged in three rows each of five. There are two screws on either side of the pins which are used to provide the security while placing the cable pin into the socket. These screws possess ridge edges so that they can be tightened or loosened by our hand without using a screw driver.
Varieties of VGA cables are available at different prices. The cables which are more expensive are provided with gold plating on the plugs or shielding in order to prevent the wires from causing interference. This is a small improvement and generally it does not cost more. There is not much difference in the picture quality between the extremely cheap VGA cable and an averagely priced cable of the same type. But, you can find much more significant picture quality in the expensive VGA cable as compared to the lowest price cable of this type. Ensure that while buying this cable, choose the shortest length as per your requirement because this will prevent signal degradation.
VGA cable is also used in game consoles. The picture quality using this cable is better as compared to the older cathode ray televisions.
