1:4 DVI Splitter

One DVI input, Four DVI outputs


DVI (Digital Visual Interface) is a common connector used throughout the industry to connect digital video displays to video sources such as computers.

Gefen’s 1:4 DVI Splitter is a distribution hub that sends the same DVI graphics source to up to four DVI digital displays (flat panels or projectors). It is a reliable solution that accommodates four digital video displays at the same time, creating a multi-viewing environment that maintains the highest resolution video at all times.

The Gefen EXT-DVI-144N 1×4 DVI Splitter distributes a single DVI source to up to four DVI dual link outputs without losing quality or resolution. It works with any dual link DVI computer supporting internal, downstream, and custom EDIDs. This product can be placed on a shelf or other horizontal surface, or be mounted in a standard 19-inch wide rack, using the included rack ears.
