Are DVI-I and DVI-D Compatible?

DVI-I and DVI-D are partially compatible. It is possible to use a DVI-D cable in a DVI-I connection. However, using a DVI-I cable for a DVI-D connection is not possible. DVI-D is digital signal only, while DVI-I is both digital and analog signal. The long flat pin on a DVI-I connector is longer than the same pin on a DVI-D connector, and it also contains an extra 4 pins. This means that it is physically not possible to fit a DVI-I connector into a DVI-D connection.

For example, most computers have a DVI-I connection, while flat screen monitors have a DVI-D connection. You would need to use a DVI-D cable to connect your computer to your display.
