The Gefen 1:2 Splitter For HDMI
The 1:2 Splitter for HDMI 1.3 allows set-top boxes, DVD players, DVRs and other
HDMI sources with an HDMI output to be connected to two HDMI-compliant
displays while also supplying digital audio to an external amplifi er or receiver. A
TOSLINK output on the 1:2 Splitter allows connection of an external amplifi er or
receiver for greater installation fl exibility. A greater number of displays can be split
by daisy-chaining multiple 1:2 Splitters together to create a larger distribution.
How It Works
An HDMI source connects to the HDMI input connector on the Gefen 1:2 Splitter
for HDMI 1.3. Two HDMI outputs from the 1:2 Splitter connect to two HDMIcompliant Displays. Vibrant, sharp HDMI video with embedded multichannel
digital audio will now be observed on the HDMI Displays. TOSLINK digital
audio output on the rear of the unit allows connection of an external amplifi er or
receiver.
Note:
HDMI output 1 is connected to the Primary Display, from which the video
resolution, timing information and audio formats (EDID) is obtained. This
information is used to create an identical picture on the Secondary Display. Both
HDMI displays must be capable of the same video resolution(s) or the Secondary
Display may not show a picture.
DVI video may be input to the Splitter with an optional DVI-to-HDMI adapter
cable.
INTRODUCTION

READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE 1:2 SPLITTER FOR HDMI
• 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 1:2 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 1:2 Splitter for HDMI
1.3 that can be used instead. Please see page 6 for more details.
• HDMI/HDCP compliant
• Compatible with all HDMI and DVI* displays
• The digital TOSLINK output only supports the transmission of the following
audio formats:
- LPCM 2-channel (32 ~ 192 Khz sampling rate)
- Dolby AC3 2-channel and 5.1-channel
- Dolby Digital Plus 5.1-channel
- DTS 2-channel and 5.1-channel
• LPCM of more than 2 channels, Dolby Digital Plus of 7.1 channel, DTS-HD, and

or device.
4. Plug the 5V DC power supply into the 1:2 Splitter for HDMI 1.3.
NOTE: By Default, the display information from the display connected to HDMI
output port 1 is sent back to the source. Therefore, the other display that is
connected to the 1:2 Splitter for HDMI 1.3 must be capable of accepting the
timings and resolutions 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

the 1:2 Splitter for HDMI 1.3 that can be used instead. Please see below for the
activation process.
EDID MODE
The HDMI 1:2 has an EDID button which will determine if the EDID is used from
the display attached to output 1 (Ext. mode) or if the onboard EDID (Int. mode)
will be used.
The current EDID mode can be determined by which EDID mode LED is active on the front panel. The Ext LED will indicate that the external EDID (from
output port 1) is being used, and the Int LED will indicate that the internal preprogrammed EDID is being used.
If you want to use the onboard EDID, press the EDID button on the rear panel
and then press the reset button to activate the new EDID mode. To revert back
to using the external EDID, press the EDID button again and then reset the unit
using the reset button to activate the new EDID mode.
