This a digital ONLY DVI-D video cable. DVI is a popular form of video interface technology made to maximize the quality of flat panel LCD monitors, TVs and modern video graphics cards. Most new video cards are coming with a DVI port on them, to take full advantage of their graphics capabilities. Some video devices also support the DVI interface, but this is gradually being phased out in favor of the more popular HDMI connection. DVI carries a video signal only, so a separate cable must be run for audio.
