The Gefen 1:4 Splitter For HDMI 1.3
The Gefen 1:4 Splitter for HDMI 1.3 allows set-top boxes, DVD players, and other
HDTV devices to be connected to four or more HDTV displays. When two or
more Splitters are connected together, they can be used to create a larger video
signal distribution.
This new unit supports HDMI 1.3 features and passes the higher bandwidth
HDMI 1.3 signal for the ultimate in state-of-the-art HDMI signal duplication.
How It Works
The HDMI 1:4 Splitter is connected using an HDMI cable from the HDMI video
source to the HDMI splitter input. There are four HDMI outputs. Each output is
connected to an HDMI display. Power is connected and all connected displays
show an exact replica of the video signal that is input to the Splitter.

OPERATION NOTES
READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE 1:4 SPLITTER FOR HDMI 1.3
• By default, display information from the display connected to HDMI output port
1 is sent back to the source. Therefore, the other display connected to the 1:4
Splitter for HDMI 1.3 must be capable of accepting the timings, resolutions
and audio formats of the display that is connected to HDMI output port 1. It is
recommended that the display with the lowest native resolution be connected to
HDMI output port 1. This is to ensure that a compatible video signal will be able
to be displayed on all connected monitors. There is a generic EDID programmed
into the 1:4 Splitter for HDMI 1.3 that can be used instead. See page 7 for more
details.

EDID MANAGEMENT
EDID Mode Selection
1. EXTERNAL MODE:
See page 8 for details on using the External EDID.
2. INTERNAL MODE:
To use this mode, press the EDID button on the rear panel until the front-
panel LED marked “Int” turns bright green. This mode will use a preset
EDID, from the factory, that is stored in the Gefen 1:4 Splitter for HDMI 1.3.
This pre-programmed standard EDID data structure is compatible with most
A/V display devices. All resolutions and audio formats specified in this EDID
will be passed to the source device. See the tables below for a complete
listing of the resolutions and audio formats listed in this EDID.
NOTE: All other HDMI devices/displays connected to the output ports MUST
be compatible with at least one resolution/audio format specified in this
EDID. It is recommended to set, on the source device, a common resolution
and audio format shared by all attached devices/displays. This is to ensure a
compatible signal is output to all connected devices/displays.
