The Gefen TV Splitter
The Gefen TV 1:4 Splitter for HDMI™ allows set-top boxes, DVD players and
other HDTV devices to be connected to up to four HDTV displays. When two or
more Gefen TV HDMI™ 1:4 splitter units are connected together, they can be
used to create a larger video signal distribution. This 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 Gefen 1:4 Splitter for HDMI™ 1.3 is connected using an HDMI™ cable from
the HDMI™ source to the HDMI™ splitter input. There are four HDMI™ outputs.
Each output is connected to an HDMI™ display. Power is cycled for all equip-
ment, then all connected displays will show a crisp, clear replica of the source
video signal.

remaining HDMI output ports will be scanned in succession and use the first
EDID that it detects. (See note on page 4 for additional information)

How to Connect the 1:4 Gefen TV Splitter
Connect the HDMI source to the 1:4 Gefen TV Splitter using the supplied1. HDMI cable.
Connect the displays (up to four) to the 1:4 Gefen TV Splitter using user2. supplied HDMI cables.
Plug the 5VDC power supply into the Gefen TV Switcher and power outlet.3.
NOTE: Display information (EDID) is sent from the display connected to HDMI
output port 1 to the source. If there is no display connected to HDMI output port
1, the remaining HDMI output ports will be scanned in succession and use the
first EDID that it detects. The source will output resolutions and timings according
to the EDID that is being fed by the display connected to output port 1. Therefore, all
of the connected displays must be capable of accepting the timings and resolution
output by the source. 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. Optionally, you
can use a generic 1080i EDID that is pre-stored on the 1:4 Gefen TV Splitter. Please
see the below section on how to use this EDID instead of using the EDID from
display output 1.
EDID Button
There is a generic 1080i EDID stored in the 1:4 Gefen TV Splitter. This can be
used instead of the EDID from display output 1. Press the EDID button on the
rear panel of the unit. The INT LED on the front panel should be lit. This will
indicate that the onboard EDID is being used in lieu of any display EDID.
Reset Button
Pressing the button will reset the unit, effectively reverting the unit to its normal
EDID routing logic.
