DVI stands for Digital Visual Interface. Designed by the Digital Display Working Group (DDWG) it provides a digital to digital connection to maximize the quality of high end flat panel monitors and video cards. When a video signal leaves the computer, it must be converted to analog for transmission over a VGA cable and then converted again to a digital signal at the monitor. Each conversion causes signal loss, affecting the quality of the final image. DVI provides a direct digital connection eliminating this conversion process. DVI-D provides a direct digital only connection. This provides a faster, higher quality connection than analog. A Dual link cable doubles the maximum bandwidth (2 x 165 Mhz) and supports resolutions up to 2048x1536 at 60 Hz or 1920x1080 at 85 Hz.
