VGA. DVI is more of a connector that provides for the same resolution as VGA, but it can also carry video information and audio information with up to 8 channels.
In summary, DVI has the following advantages over VGA: (1) it can transmit video as well as audio over a single cable; (2) it carries an uncompressed digital signal; and (3) it supports high screen resolutions beyond 1600 x 1200 pixels. But, most displays sold today use a VGA connection. In other words, unless your computer supports HDMI or DisplayPort connections or if you need one of the three advantages listed above, use a VGA connection when connecting to your display.”
