digital visual interfaceShort for Digital Visual Interface, DVI is a video display interface. It was developed to be an industry standard for transmitting digital video content to display devices at resolutions as high as 2560 x 1600. Common devices that utilize the DVI connection are computer monitors and projectors. DVI can even be used with some TVs, although HDMI is more common as only some DVI cables can transmit audio signals. The DVI connector (shown below) may have one of three names depending on the signals it supports: DVI-A (analog only), DVI-D (digital only), or DVI-I (both digital and analog).


If you have a monitor and GPU that support both DVI and VGA, we suggest going with a DVI cable as the picture quality will always be better with digital (and most analog) sources.
