A VGA cable is a lead used for transmitting video signals. It is most commonly used to link computers with monitors. However, it is now used on some high definition televisions.

VGA stands for video graphics array. It was a graphics standard used by IBM in its early PCs sold in the 1980s. Today all PCs support VGA, but most of them use a more advanced system depending on the actual monitor used. The Windows loading screen appears using VGA as it is seen before the computer loads the relevant information about the monitor to use.

VGA today generally refers to the type of cable used to carry the display signals, regardless of the actual graphics system being used. It’s characterized by 15 pins on the plug in three rows of five. The plug also has two screws, one either side of the pins, which secure it into place in the socket. These screws have ridged edges meaning they can be tightened and loosened by hand rather than needing a screwdriver.

There are a wide range of VGA cables available at differing prices. More expensive models offer features such as gold plating on the plugs, or shielding to prevent the individual wires from causing interference. However, many people believe these offer little improvement and generally aren’t worth the extra costs. As a rule of thumb, the difference in picture quality between an extremely cheap VGA cable and an averagely priced one will be much more significant than between an averagely priced VGA cable and an expensive one. It’s also worth making sure you buy the shortest cable which meets your needs as this will prevent signal degradation.

As well as computers, a VGA cable can be used with some games consoles, including the Microsoft Xbox 360. This allows the console to be used with a computer monitor, which may offer a better quality picture than older cathode ray televisions, particularly for games which have fine detail or small text. However, the quality will not be as good as with a television set that can connect to the console through a component video connection or a high-definition input such as HDMI. This means that it is more of a makeshift option.

Some high definition television sets have a VGA input. There is a great debate about whether an analog signal such as that carried by a video cable can offer picture quality as good as the digital signal carried through methods such as HDMI. There is also a problem that some television sets with multiple sockets only have advanced picture processing features switched on for digital connections. However, the relatively low price of a VGA cable means this option is worth trying out before you decide to switch your screen or input device to models which carry digital signals.
