DVI Adapters come in three distinct types. DVI-A (analog), DVI-D (digital) and DVI-I (integrated; analog and digital). Both DVI-I and DVI-D adapters have two distinct data rates, also known as single-link and dual-link. Each link type has a maximum allowed data rate that ensures data is not corrupted when transferred from the video card to the monitor.

DVI uses Transition Minimized Differential Signaling to transmit data over one twisted wire pair. A single-link DVI adapter consists of four TMDS links. Three of the four links correspond to the red, green, and blue RGB video signals, while the fourth is a clock control channel. Single-link connectors operate up to 165MHz and offer 1.65Gbps of bandwidth. They support resolutions up to 1920×1200 at a refresh rate of 60Hz.
