Here we introduce the description of the vga connector in Wikipedia
A Video Graphics Array (VGA) connector is a three-row 15-pin DE-15 connector. The 15-pin VGA connector was provided on many video cards, computer monitors, laptop computers, projectors, and high definition television sets. On laptop computers or other small devices, a mini-VGA port was sometimes used in place of the full-sized VGA connector.
Although many devices still include VGA connectors, and VGA generally coexisted with the DVI standard, VGA and DVI are both being rapidly phased out in favor of the newer and more compact HDMI and DisplayPort interface connectors.
Generally speaking, the vga connector is also called DE15 connector, but in China, the wire-type vga connector we called: DB15 connector plug-in vga connector called: HDP15 connector; Bend-type vga connector called: HDR15 connection So the face of different customers at home and abroad, we should be clear that every name.
