Two decades ago, VGA ports used to be the only video interface standard in consumer computers. However, they are being phased out now. You will only see them on old projectors, monitors and TVs. The biggest downside of the VGA is the fact that it is an analogue interface. Unfortunately, it results in a poorer quality video compared to DVI. In addition, the VGA has a maximum resolution of 640 x 480 with a refresh rate of 60 Hz, while the DVI connector boasts a single-link resolution of up to 1920 x 1200 pixels or a dual-link resolution of 2560 x 1600. Because of this, the VGA is an almost obsolete technology because of its limitations.
