DVI
Digital Visual Interface (DVI) transfers full-resolution analog or digital signals between
computers or HD video devices and flat-panel displays or projectors. DVI connectors
have up to 24 pins plus four additional pins for analog signals. Not all devices use all
pins, so read the documentation included with your equipment before purchasing
DVI cables and making connections.

DVI supports single- and dual-link connections. Single-link DVI connections are limited
to 2.6 megapixels with a refresh rate of up to 60 Hz. Dual-link DVI connectors extend
the number of pixels that can be transferred per second to drive larger displays.
