VGA monitor port on a graphics card

Standard analog interfaces to connect a monitor to a PC using a 15-pin Mini-D-Sub connector, aka HD15. With the right adapter, you can also connect an analog monitor to a DVI-I (DVI-integrated) interface as well. The VGA connector carries RGB signals for red, green, and blue color values, as well as horizontal (H-Sync) and vertical (V-Sync) information.
