that harness integration, extension, distribution and conversion technologies.
Gefen’s reliable, plug-and-play products supplement cross-platform computer

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.

READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE 4X4 DVI DL MATRIX
• The 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.

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 definite
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 verified
that it is outputting video before moving on to power the next source.

The 4x4 DVI DL Matrix has a bank of 8 configuration 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 configuration options. By default, all
Dip Switches are in the OFF position. Each setting is outlined below.
Switch 1 IR Remote Channel Configuration
Switch 2 IR Remote Channel Configuration
Switch 3 Automatic Link Selection \ Dual Link Only Mode
Switch 4 Not Used
Switch 5 Pre-Empahsis For Display Output 1
Switch 6 Pre-Empahsis For Display Output 2
Switch 7 Pre-Empahsis For Display Output 3
Switch 8 Pre-Empahsis For Display Output 4
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.

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.
