Vga Cable - Using A Vga Cable

VGA Cable or Video Graphics Array cable is a cable that is used to connect a monitor or display to a personal computer

. The VGA standard was defined in the late 1980s and is sold on products produced today. You can find the VGA connector on anything from projectors, to personal computers, laptops and a host of devices that may require additional or larger screens. Typically the VGA connector itself will be blue similar to the ends of the cable. The blue color coding exists to help ensure that it is plugged in only where compatible.

Serial cables might have what looks like the same connector, but a closer inspection reveals that they only have 9 pins compared to the monitor cables are standard of 15. Occasionally you may notice that your Video Graphics Array Cable may have what seems to be some pins missing. This isn't the case and the fact is, some pins are not used as they were reserved for standards or devices no longer in use. One thing to look for when selecting a good quality cable is thickness. A thicker cable indicates larger gauge wires, and additional shielding inside the cable. It is important to shield a cable as it helps prevent crosstalk, which is where signals from other wires inside the cable interfere with other wires causing a complete host of problems.

Crosstalk and noise can also come from outside interference and is a problem with long VGA cables; that is noise from an outside source. Perhaps you notice some static when turning a set of speakers on. To avoid problems like these ensure you use a well shielded, high quality monitor cables. Although the VGA isn't the only option for connecting a display it is one of the most common interfaces. Some others include DVI, HDMI and Display Port.

If you want to connect a personal computer and a monitor or a display together, then the VGA cable is the right cable for you to use. This standard has been in place since the 1980s, and is the type of cable that is commonly found bundled with brand new monitors and other computer systems. For questions on buying VGA (Video Graphics Array) cords for various purposes, speak to a specialist in a computer repair store or the manufacturer behind your computer monitor to have your questions answered. This is the best way to make sure that you are getting the right type of cable for the computer system that you are using.
