The VGA video adapter is an extremely common connector employed for computer display. Originating from the 1987 IBM PS/2 model, the 15-pin connector went onto to become prevalent on computers, monitors and even high definition televisions. The simple aim of the VGA was to provide an image that could be transmitted via computer monitor into a compatible VGA projector or video-wall for a seamless display. VGA was not designed to be a replacement for the DVI interface though; in fact, it was originally intended to be a more backwards-compatible replacement for the older DVI interface.
Since it was to replace the aging DVI interface, and as a result, the need for DVI monitors also diminished, manufacturers of computers and other peripherals switched to VGA as the new standard format. However, due to the popularity of VGA, there were still a good number of manufacturers that still produced DVI based monitors. As such, when choosing monitors, DVI monitors often came with an option to convert the monitor into a VGA compatible format. At this point, the term VGA to VGA was beginning to be used to identify whether or not the monitor used VGA to connect to a VGA projector or video-wall.
To change your monitor to a VGA compatible monitor, you will first need to acquire a VGA cable. This will allow you to convert the VGA signals into digital signals for transmission over a VGA computer. There are two types of VGA connections; analog and digital. An analog vga cable will carry two digital video signals, whereas a digital vga cable will carry only one digital signal. Connectors that use analog VGA connections must be connected to a video graphics array through an adapter that carries only one digital signal.
In order to use your computer without converting it to VGA, you can utilize a dvi interface. A dvi interface is a special type of connection that allows you to view digital video signals on a normal analog VGA monitor. Because the dvi interface uses more memory than a regular VGA connection, it is commonly used as an alternative. A majority of computer motherboards contain slots for dvi interfaces.
The last type of VGA connector that we will discuss are pcs or part ports. This port is used for digital cameras, projectors, scanners, printers, and other computer peripheral devices. Pixart ports connect to VGA, DVI, or s-video monitors using different adaptors.
Although the use of VGA to connect to a computer has been widely used for years, its uses have been limited to implementing high resolution graphics on desktop computers. As a result, when designing a graphics card or adding a projector to a new computer system, most people tend to omit VGA from their list of VGA connections. However, in recent years, with the advent of new technologies like the e-reader and other mobile devices, there has been a rise in the use of VGA for connecting a computer system to a digital display device. Nowadays, many computer system manufactures include VGA connections in their systems.
