There are at least four versions of the VGA connector, which are the three-row 15 pin DE-15 (also called mini sub D15) in original and DDC2 pinouts, a less featureful and far less common 9-pin VGA,. The image and below table are the newer 15-pin VESA DDC2 connector. Note that the pin numbering in the diagram is as seen looking towards a male connector; the pin numbering on the female connector as present on a graphics card at the back of a computer is the mirror image of that shown.
The common 15-pin VGA connector found on most video cards, computer monitors, and other devices, is almost universally called "HD-15". HD stands for "high-density", which distinguishes it from connectors having the same form factor but only 2 rows of pins. However, this connector is often incorrectly referred to as a DB-15 or HDB-15.
"VGA connectors" and their associated cabling are almost always used solely to carry analog component RGBHV (red - green - blue - horizontal sync - vertical sync) video signals along with DDC2 digital clock and data.
Where size is a constraint (such as laptops) a mini-VGA port can sometimes be found in place of the full-sized VGA connector.
