What are VGA cables

VGA cables (Video Graphics Array) are the connector. VGA cables are also known as RGB connector, D-sub 15, mini sub D15 and mini D15. There is a three-row 15 pin DE-15 while there are four versions such as original and DDC2 pin outs, the much older and less flexible DE-9 connector, and a Mini-VGA used for the laptops.
The common 15-pin VGA connectors are found on most video cards, computer monitors, high definition televisions, which in turn support VGA connections, as well as other devices, is almost universally termed “HD-15″. HD stands for ‘high-density, which differs it from the connectors, having the same form factor but only 2 rows of pins. But, this connector is often wrongly referred to as a DB-15 or HDB-15.
VGA cables and connectors and their associated cabling are always used to carry analog component RGBHV, video signals along with DDC2 digital clock and data. However, the size is a constraint as a mini-VGA port can often be found in place of the full-sized VGA connector. On Microsoft Windows, there is no software provided option to disable plug and play monitor detection. This leads to problems with computer or monitor switching applications as well as causes computer games to select display resolutions higher than the monitor is physically capable of displaying resulting in a garbled display. In this circumstance, it might be necessary to remove pin 12 from the monitor VGA cables to disable plug and play monitor detection.
