Video Graphics Adapter [VGA] interface is used as an interface between a Personal Computer and a Monitor. The VGA interface was introduced in 1987 which was followed by Super VGA [SVGA] in 1990. So the signal pinout listed on this page is obsolete, use the pin out on the SVGA page instead.

VGA is a superset of EGA, incorporating all EGA modes. Older displays sent digital signals to the monitor, while VGA and later standards send analog signals. This change was necessary to allow for more color precision. The EGA video display interface is OBSOLETE.

The VGA interface provided a resolution of 640 x 480 pixels at a bandwidth of 36MHz, with the SVGA screen resolution having 800 x 600 pixels at a bandwidth of 45MHz. The VGA Interface bus uses either a 9-pin or 15-pin D-sub connector. The table below provides the pinout and signal names for either the DB15-pin or DB9-pin video connector.

The connector may be advertised having a number of different options. Assuming a 15-pin VGA connector on both the Monitor and PC; the cable will indicate 15 pins. The 15-Pin connector will have 3 rows of 5 pins or sockets. DB is the family, HD [High Density] is the style, M is Male [Pins], F is Female [Sockets]. Normally Equipment [PCs and Monitors] use sockets, so the cable needs to have pins [Male] to mate with the device. A normal cable may indicate HD15 Male to HD15 Male, or DB15 Male to DB15 Male, or high-density DB15 connector. In some cases the connectors may be called a mini-sub D15. The conductors will be 28 AWG in size. The length of the cable will vary depending on the quality, the better the cable is made the longer the length. When the cable uses a 15-pin connector and indicates a certain resolution then it may also comply with the SVGA standard. A Shielded cable is better then a non-Shielded cable. The cable may also indicate it contains EMI beads to reduce noise, again it may be a higher quality cable.

A listing on OEM D-sub connector manufacturers may be found on the Connector Manufacturers page, and this page points to Cable Assemblies.

DVI has a number of different types connectors:
DVI-D Digital only connector; 24 pins [modified D style];
DVI-A Analog only; [modified D style], I don't think this is part of the standard
DVI-I Digital and Analog [RGB]; 29 pins [modified D style]
DFP Digital Flat Panel, Digital only connector. Pinout is listed on the DFP page
