VGA is short for Video Graphics Array. It is a display hardware that came bundled with the IBM PS/2 PC line which was introduced in 1987. Since then, it has been adopted as an analog computer display standard. It is featured as a 15- pin 640 by 80 resolution or a D-subminiature VGA connector. Although it was superseded in the birth of personal computers, it is still a popular resolution among many mobile devices and even TV sets. So if a TV lacks a VGA port, you can use an adapter to connect to the TV and receive signals from a computer.
A Closer Look at VGAVGA is noted as IBM's last graphical standard which they introduced to numerous PC clone manufacturers. Since then, it has become the lowest common denominator for all personal computer graphics hardware to ever be implemented without any kind of device-specific software. A good example would be the MS Windows splash screen which appears while it operates on VGA mode. This is the reason why the screen appears in reduced color depth and resolution.
After VGA, the XGA standard followed. The latter is still a product of IBM. However, XGA was superseded was later on superseded by several slightly different extension to that of VGA which are made by clone manufacturers. This gave birth to Super VGA.
VGAs make use of a connector or a three-row 15-pin DE-15 connector. You can find this connector in different devices like:
* Computer monitors
* Video cards
* High definition TV sets
For laptops and small devices, only a mini-VGA port is used as an alternative to a full-sized VGA connector.
Other terms for DE-15 or VGA connector are:
* Mini sub d15
* D-sub 15
* DB-15
* Mini D15
* HD-15
* HDB-15
* HD15
The terms vary in order to distinguish it from other older as well as less flexible connectors like DE-9 which are used on older versions of VGA cards. Basically, the later has the same shell but it only has two rows of pins.
How does VGA connectors and cables work?
D-sub connectors having 15 pins are used by VGA cables to carry analog video signals for RGB color channels. RGB stands for red, green and blue, respectively. These cables also carry vertical as well as horizontal sync and other monitor data.
Most high-definition TVs support Video Graphics Array connections to computers. Just a male to male cable is required. In this case, you can connect VGA to TV sets via:
* VGA to DVI
* VGA to RCA
