VGA - Video Graphics Array

HIS Technology, January 1, 2008

A VGA connector as it is commonly known (other names include RGB connector, D-sub 15, mini sub D15 and mini D15) is a three-row 15 pin DE-15. There are four versions: original and DDC2 pinouts, the far older and less flexible DE-9 connector, and a Mini-VGA used for laptops.

The common 15-pin VGA connector found on most video cards, computer monitors, high definition televisions which support VGA connections, 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 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
