What is the difference between D-SUB and VGA interface? Are they the same?

It can be said that they are the same thing. More specifically, VGA is for use with 15-pin D-sub connectors. Comparing them is an act of disambiguation because D-sub is a standard electronic connector typically used for VGA, so if you're talking about D-sub for computer monitors, you're probably referring to the VGA connector.


 

To reiterate, VGA is the A/V interface, and D-sub is the connector type it was chosen initially for (by IBM for the IBM PS/2 personal computer circa 1987).

 

VGA and D-Sub vs. A/V standards

Comparing VGA and D-Sub to each other makes about as much sense as comparing a human being to his or her head or limbs. D-sub is part of how VGA works, although D-sub is also commonly used for other purposes, such as serial and parallel ports.

 

What is D-Sub?

D-sub（The D-subminiature） is a D-shaped electrical connector invented back in 1952. It features a D-shaped metal shield that provides EMI shielding, ensures proper orientation, and provides solid mechanical support. All other D-sub interfaces have become obsolete due to advances such as SAS and USB.

 

What is VGA? 

VGA is short for Video Graphics Array video connection interface is a PC monitor connection standard that became popular in the 21st century thanks to gamers who liked its zero-latency connection and ability to support image quality up to 2048 x 1536 resolution.

 

The Video Graphics Array video connection interface is a PC monitor connection standard that became popular in the 21st century thanks to gamers who prefer its zero-latency connection and support for image quality up to 2048 x 1536 resolution. In addition, it is an analog standard used primarily for older monitors and desktop computer models. IBM originally developed VGA in 1987 for its IBM PS/2 PCs. Still, PC clones adopted (stole) VGA to make it the standard for monitor connections in the 1990s.
