satisfaction is very important to us.
Gefen
Gefen delivers innovative, progressive computer and electronics add-on solutions
that harness integration, extension, distribution and conversion technologies.
Gefen’s reliable, plug-and-play products supplement cross-platform computer

The Gefen 4x4 VGA Matrix
The Gefen 4x4 VGA Matrix offers flexibility and convenience by routing high-
quality VGA and analog audio from any of four VGA/audio sources to any of 4
VGA displays and audio devices.
The Gefen 4x4 VGA Matrix works with a wide variety of VGA sources such as
computers, security cameras and DVRs. Every source is accessible at any time
by any display by selecting it with the included IR remote, front panel buttons, or
RS-232 control.
How It Works
Connect up to four VGA and analog audio sources to the 4x4 VGA Matrix’s
inputs. Connect the Matrix’s VGAand analog audio outputs to 4 VGAdisplays
and audio devices. Plug in the Matrix’s power supply. You may now switch VGA
and audio sources using the included IR remote, front panel buttons, or the built-
in RS-232 serial port. LED lights on the front panel show the currently selected
routes from the VGA sources to the VGA displays.
INTRODUCTION
READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE 4X4 VGA MATRIX
• The 4x4 VGA Matrix does not transmit display information (EDID) to the
source. Standard VESA resolutions should be output by most computers
without the need of an EDID. If using a non-VESA standard resolution or
if EDID is needed, an EDID storage and relay device is necessary. Gefen
recommends the use of a DVI Detective (part# EXT-DVI-EDIDN) with two
VGA to DVI adapters.
