VGA Monitor Cable

Video Graphics Array – more commonly known as just VGA – represents the minimum standard of resolutions of color in electronic devices, especially computer monitors. It is usually the most compatible color resolution, and hence, it is the most popular among other color resolutions. The VGA is typically identified by a total of 32 colors. In addition, it has a resolution that measures by 640 x 480. The resolution can be increased or decreased with the help of a device driver.

The VGA takes its inspiration from CGA (Color Graphics Adapter) which was developed by International Business Machines (IBM) during the year 1981. The highest resolution attainable from CGA was 640×280. In addition, it had only 8 colors in its palette, with a size of only 4 bits. However, when CGA was first invented, it rose to popularity since the only other color resolution standards were either of two colors or of only one color (monochrome). As a result, CGA quickly found its place in the latest line of personal computers developed by IBM – known as the IBM PCs. Since then, the CGA underwent major developments. For instance, only three years after its invention, it was modified into EGA (Enhanced Graphics Adapter) – which had 16 colors in its palette and provided a resolution of 640×350. This EGA was incorporated in the line of IBM PC Advanced Technology (also called PC-AT or just AT). After a period of three additional years, the idea of VGA came to life. It was quickly incorporated into most graphics cards and adapters. Even though IBM did develop other advanced forms of VGA, such as extended Graphics Array (XGA), none could be as popular as VGA. However, even though it is the most compatible, its low resolution can also be a limitation. As a result, it is only used in the absence of other display standards.

VGA cables are required in order to use it. They can be used by both computers and HD TVs (high definition televisions). The VGA cables that are used for connecting monitors with computers are known as VGA monitor cables. The main purpose of VGA cables is the transmission of video signals.

The VGA is most commonly seen when the Windows operating system first loads into the screen. This is when it takes the computer some time to acquire all the data from the monitor. As a result, the computer uses the VGA mode during that time.

Even cables which are not necessarily for viewing VGA displays are sometimes called VGA monitor cables. These cables usually have 15 pins located over their plugs. The pins are arranged in a total of three rows, each containing 5 pins. In addition, there are two screws at both ends of the pins. These screws are used to hold the pins in their positions (that is, inside the sockets). The edges of the screws have ridges so that screwdrivers are not required for loosening and tightening the screws; using the hand is good enough.

A lot of manufactures produce VGA cables. As a result, they can be found with different features and prices. In general, the higher the number of features, the greater is the price. For instance, VGA monitor cables that have gold plating or shielding over their plugs cost much more than regular cables which do not come with such features. However, a few of these features are beneficial, and should not be ignored because of the high price. For instance, the gold plating or shielding prevents one VGA wire from interfering with another. If there is any interference between the wires, then the signal received by the cable will be weak, and as a result, the quality of the picture will deteriorate. VGA monitor cables that are too cheap should not be bought since they often provide extremely poor quality pictures. Furthermore, the buyer should be aware of the fact that longer VGA cables are not necessarily better. It is true that long VGA cables can fulfill some requirements that short VGA cables cannot, but long VGA cables have greater chances of facing interference between individual VGA wires. This interference can be minimized by using shorter VGA cables.

A few gaming consoles can also make use of VGA monitor cables. A great example of such consoles is the Microsoft Xbox 360. In this case, computer monitors are required since the games usually show small-sized texts and details. If, however, the cables are used with televisions, the user cannot view the minute text – even though the quality of the picture may be better. This is because the monitors, unlike television sets, do not have component video connections for receiving high definition video inputs like HDMI. As a result, when used with monitors, VGA cables receive less information when comparing them with television screens.
