The Gefen 4x4 DVI DL Matrix  
Easily combine any four cross-platform Dual Link DVI video display outputs and  
four Dual Link DVI digital displays without networking. Our 4x4 DVI Dual Link  
Matrix provides a simple, reliable and highly effective method of creating multiple  
Dual Link DVI display consoles, with each console capable of accessing any one  
of the Dual Link DVI video sources at any time by remote control. You also have  
the option of setting up the four displays locally or extending them with a Gefen  
extender.  
How It Works  
The 4x4 DVI Dual Link Matrix has four Dual Link DVI inputs and four Dual Link  
DVI outputs. You simply connect your four Dual Link DVI video sources to the  
Switcher’s inputs, then connect your four Dual Link DVI displays to the Switcher’s  
outputs.

OPERATION NOTES  
READ THESE NOTES BEFORE INSTALLING OR  
OPERATING THE 4X4 DVI DL MATRIX  
4x4 DVI DL Matrix does not have any scaling functionality. All of the attached  
monitors must be able to display the attached sources’ resolution. For  
maximum compatibility it is recommended that only one compatible/common  
resolution for all displays be used by all sources.

CONNECTING AND OPERATING THE 4X4 DVI DL MATRIX  
How to Connect the 4x4 DVI DL Matrix  
1. Connect up to 4 DVI DL sources to the 4x4 DVI DL Matrix input ports using  
the supplied DVI DL cables.  
2. Connect up to 4 displays to the 4x4 DVI DL Matrix output ports using user  
supplied DVI DL cables.  
3. Connect the supplied 5V DC power supply to the 4x4 DVI DL Matrix.  
4. Power on the displays.  
5. Power on each source individually ensuring that a display is pointing to it  
while the power on procedure completes.  
NOTE: It is extremely important to ensure that when each source is being  
powered on it has a display pointing to it. Most sources require (a denite  
requirement if computers are being used) a display to be attached to  
receive EDID (display information) and to begin operation. If a source  
does not have a display that is pointing to it, a video image may fail to be  
displayed. It is recommended that each source be powered on and veried  
that it is outputting video before moving on to power the next source.

CONFIGURING THE 4X4 DVI DL MATRIX  
The 4x4 DVI DL Matrix has a bank of 8 conguration DIP SWITCHES. These  
switches are located underneath the unit. Peeling back the black metallic sticker  
on the bottom of the 4x4 DVI DL Matrix will reveal the Dip Switch bank. These  
service switches are used for a number of conguration options. By default, all  
Dip Switches are in the OFF position. Each setting is outlined below.

IR REMOTE CHANNEL CONFIGURATION  
Dip Switches 1 and 2 relate to the IR remote control channel that is used by the 4x4  
DVI DL Matrix and RMT-16-IR remote control. Dip Switch 1 and 2 on the 4x4  
DVI DL Matrix must match Dip Switch 1 and 2 on the RMT-16-IR remote control.  
Please view the table below to set the channel on 4x4 DVI DL Matrix and IR  
remote control. The remote channel for the RMT-16-IR is located underneath it’s  
battery cover.

CONFIGURING THE 4X4 DVI DL MATRIX  
AUTOMATIC LINK SELECTION / DUAL LINK ONLY MODE  
The 4x4 DVI DL Matrix has the ability to run both Single Link and Dual Link DVI  
sources. There is a feature that will either automatically select the link mode, or lock  
the unit in Dual Link mode. By default, Dip Switch 3 is in the OFF position (Automatic  
Link Selection). Turning Dip Switch 3 to the ON position will lock the unit in Dual Link  
mode and will only allow Dual Link signals to pass properly.  
PRE-EMPHASIS  
Pre-Emphasis is used to help extend a signal travel over a distance of cable. When  
a DVI cable connected to a display is over a long cable, it is recommended that  
Pre-Emphasis be enabled. Pre-emphasis is enabled by default on all display  
outputs. For short cables, disable pre-emphasis on each output by turing it’s  
corresponding Dip Switch to the ON position. If any type of extension device is  
used pre-emphasis must be disabled for proper operation.
