Digital Visual Interface ( DVI )

Digital Visual Interface ( DVI ) cables are designed to connect your PC to a flat panel monitor, LCD projector, HDTV, etc. DVI cables are available in DVI-D and DVI-I formats.

DVI-D cables allow for digital transmissions between host and display devices.
DVI-I cables allow for digital and analog transmissions.

DVI-D and DVI-I cables are available in single-link and dual-link formats. Dual-link cables provide a faster and stronger signal strength than single-link cables and thus allow for superior resolution on your LCD device.
