RGB ports are often called VGA ports.

Red, green and blue (RGB) ports support colors and color signals that are displayed on a computer monitor. Though RGB ports are called video graphics array (VGA) ports, at least one RGB port exists with a structural difference.



Most VGA ports have five pins each in three rows, totaling 15 pins.
