A VGA connector (also RGB connector, D-sub15, mini sub D15, and mini D15 connector), is a three-row 15-pin DE-15 connector, of which there are four versions: (i) the original VGA15 pinout connector, (ii) DDC2 pinouts, (iii) the older, less flexible DE-9 connector, and (iv) the Mini-VGA used for laptop computers.
The 15-pin VGA connector is common to most video cards, computer monitors, and high definition television sets that support VGA-connector devices. It usually is known as an “HD-15” (High Density 15) or “DE-15”, distinguishing it from connectors of like form factor, but with only 2 rows of pins. Occasionally, this connector is incorrectly referred to as a “DB-15” or as an “HDB-15”.[citation needed] VGA connectors and cables are used solely to carry analog componentRGBHV (red - green - blue - horizontal sync - vertical sync) video signals, a Display data channel (DDC2) digital clock, and data. When device size is a spatial constraint (i.e. laptop computers), a mini-VGA port occasionally is in place of the full-sized VGA connector.
