Digital Visual Interface (DVI) is the standard interface for high-performance connection between PCs and Flat Panel Displays, Digital CRT Displays, Projectors, and HDTV. DVI Analog Video Cables deliver the high-performance, high-bandwidth interface needed for video displays of today and leaving headroom for the products of tomorrow. DVI-A cables are designed to carry only an analog signal. It is perfect if you have a newer graphics card with a DVI output but have a monitor that only supports VGA. DVI cables are used with newer video cards and monitors for higher resolution. DVI-D (Digital) can not convert to VGA (Analog). Only DVI-A (Analog) can be converted into VGA (Analog).
