An RGB connector is a type of video connector used to convey a video signal between display device and a workstation video monitor. It utilizes multiple cables that have their own shielding, which allows an RGB connector to provide a better image quality when compared to the VGA standard.
As of 2015, RGB connectors are part of an obsolete video standard that can only be used with monitors that have analog ports. RGB connectors feature three separate cabling standards: RGB5, RGB4 and RGB3. The number indicates the number of cables that carry specific color signals in addition to horizontal, vertical and composite synchronization. The three basic color signals carried by an RGB connector are red, blue and green.
