The Gefen 4x4 Matrix for HDMI 1.3
The 4x4 Matrix for HDMI 1.3 routes high definition at resolutions up to 1080p
with multichannel digital audio from any four HDMI sources to any four displays.
The 4x4 Matrix eliminates the need to disconnect and reconnect HDMI sources.
It works with any HDMI source that connects to an HDMI display, supporting
advanced digital audio formats such as Dolby TrueHD and DTS-HD Master
Audio. 3D content can be displayed when connecting a 3DTV and 3D source.
Each source is accessible at all times by any display by selecting it with an IR
remote, or using the RS-232 port to switch the unit.
How It Works
Connect any four HDMI sources to the Matrix’s HDMI inputs. Then connect four
HDMI devices or displays to the Matrix’s outputs. Once the sources, the Matrix
and the displays are powered on and connected, select which sources you want
to view on the displays using the IR remote or RS-232 connectivity.

READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE 4X4 MATRIX FOR HDMI 1.3
• You should connect all the cables and power supply prior to connecting
power to the HDMI sources and 4x4 Matrix for HDMI 1.3.
• When powering the sources, the display needs to point to the source input.
• 3D content can be displayed by connecting a 3DTV and 3D source.
• Display information (EDID) is needed by the source devices to determine the
capabilities of the connected display. This is especially important for HDMI
1.3 sources because without the right information in the EDID none of the
features for HDMI 1.3 will be enabled. The 4x4 Matrix for HDMI 1.3 features
an EDID selection that will allow the user to choose from a external EDID
from an attached display or a built-in internal EDID. Please see page 7 for
more details.

How to Connect the 4x4 Matrix for HDMI 1.3
1. Connect up to 4 HDMI source devices to the 4x4 Matrix for HDMI 1.3 using
the included HDMI cables.
NOTE: The display connected to the port labeled OUT 1 will have its EDID
used when the external EDID mode is active. If there are displays with different
resolutions in the setup it is recommended that the display with the lowest
resolution be placed on the HDMI port labeled OUT 1. This way, all of the
displays should be able to display an image when the external EDID mode is
active.
2. Connect up to 4 HDMI capable devices (i.e. displays) to the 4x4 Matrix for
HDMI 1.3 using user supplied HDMI cables.
3. Connect the included 5V DC power supply between the power input on the
unit and an open wall power socket.
4. Power on all output devices (i.e. displays) first and the source devices
second.

EDID MODES
EDID. What is it and what is it used for?
Under normal circumstances, an source device (digital and analog) will require
information about a connected device/display to assess what resolutions
and features are available. The source can then cater its output to send
only resolutions and features that are compatible with the attached device/
display. This information is called EDID (Extended Display Information Data)
and a source device can only accept and read one EDID from a connected
device/display. Likewise, the source an only output one resolution for use by a
connected device/display.
Why is EDID so important with the 4x4 Matrix for HDMI 1.3?
The 4x4 Matrix for HDMI 1.3 is complex piece of technology that replicates and
switches between multiple inputs and outputs. Each connected source device will
require one EDID to read. EDID management is carefully handled by 4x4 Matrix
for HDMI 1.3 to provide a single EDID for each source to read.
What options do I have to manage the EDID in the 4x4 Matrix for HDMI 1.3?
First, it is important to note that each source device can only output one video/
audio signal type. This includes resolutions and timings. When multiple devices/
displays are used, such as with the 4x4 Matrix for HDMI 1.3, it is important to
use devices/displays that have similar or compatible resolutions/features. This
will ensure that the single video/audio signal produced by the source device is
accepted by all of the connected output devices/displays.
The user has the option, through a switch on the rear panel of the unit, to change
between a external EDID (provided by the display connected to HDMI output port
labeled OUT 1) or a pre-programed internal EDID.
How do I change EDID modes in the 4x4 Matrix for HDMI 1.3?
Simply change the switch on the back panel of the 4x4 Matrix for HDMI 1.3 to
the desired EDID mode. The unit must be reset once the EDID mode has been
changed. Please press the RESET button on the front panel once the EDID
mode has changed.

The RMT-16IR remote control will allow the user to select which source will be routed
to which output. Each of the 4 outputs are assigned a group of 4 buttons that will
correspond to the 4 source inputs. Please use the information below when selecting
the desired source for each display.

How to Resolve IR Code Conflicts
In the event that IR commands from other remote controls conflict with the
supplied RMT-16IR remote control, changing the remote channel will alleviate
this issue. The RMT-16IR remote control has a bank of DIP switches for
configuring the remote channel that both units use to communicate. The 4x4
Matrix for HDMI 1.3 can be put into a mode that will uses its front LED array to
indicate which remote channel is being used and also give the user the ability
to modify the currently used IR remote channel. These IR channel settings must
exactly match each other for proper operation.
The DIP Switch bank on the RMT-16IR is located underneath the battery cover.
