Gefen EXT-DVI-145 DVI video splitter

EXT-DVI-145, 4 x out DVI, 1 x in DVI Gefen's 1:4 DVI Splitter is a stackable 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.
How It Works
The DVI Splitter is connected with a DVI (male to male) cable from the DVI graphic source to the DVI Splitter input. There are four DVI outputs. DVI output one is the primary connection and is used for the main display. DVI outputs two through four follow the main display.
