following analog-to-digital conversion that can occur in current digital display
devices. DVI has three subsets: DVI-A, for analog signals, DVI-D, for digital
signals, and DVI-I (integrated), for both analog and digital signals. In the future
PCs and laptops are not only equipped with DVI, but also video devices as DVD.
