Which DVI type is specifically designed for analog connections only?

The type that is specifically designed for analog connections only is DVI-A. This standard utilizes the DVI connector configuration exclusively for analog signals, which is necessary for devices such as older CRT monitors and projectors that require analog input.

DVI-A carries a signal type that is derived from the VGA standard, allowing compatibility with a wide variety of legacy devices that do not support digital signals. It's important to understand the distinction among different DVI types; for instance, DVI-D is intended solely for digital signals and cannot transmit analog data, while DVI-I supports both digital and analog signals, designed to offer greater flexibility in terms of connectivity options. DVI-C does not exist in common use or standard references regarding DVI specifications, reinforcing the fact that DVI-A is the singular type dedicated exclusively to analog transmission.
