Gefen's DVI Splitter is a stackable distribution hub that sends the same DVI
graphics source to two or more DVI digital displays (fl at panels or projectors). It
is a fl exible solution that accommodates multiple digital video displays, and when
multiple DVI Splitters are connected together, they can be used to create a 1:4
or a 1:6 distribution (one DVI input / multiple DVI display outputs). When multiple
units are stacked you can switch between all the inputs into all the outputs with the
RMT-16 remote. The confi guration of stacking multiple units must be done by Gefen
professionals.
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 two DVI outputs in each module. DVI
output one is the primary connection and is used for the main display. DVI output
two follows the main display. The DVI Splitter is using a unique DVI Bus technology
to connect multiple splitters without sacrifi cing a DVI output connection.
INTRODUCTION

READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE DVI SPLITTER
Display information (EDID) is sent from the display connected to DVI output •
1. The source will be outputting a resolution based on this EDID, therefore all
other displays connected to the DVI Splitter must be capable of displaying the
resolution and timings output by the source
• The DVI splitter will only accept and output a DVI-D (digital) signal. It will not
accept or output a DVI-A (analog) signal. A DVI-I cable can be connected to the
unit but will only pass the digital portion of that signal.
