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 specied 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 specied 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.

EDID MANAGEMENT
External EDID Management
The 1:4 Splitter for HDMI 1.3 features EDID Management. Before the source
can send video or audio signals, the source device reads the EDID (Extended
Display Identication Data) from the output devices connected to the Splitter.
The EDID contains information about what type of A/V data that the source can
send to each output device.
The 1:4 Splitter for HDMI 1.3 distributes a single source to multiple output
devices. This involves reading EDID data from more than one device.
Management of the EDID data is important to maintain compatibility between all
devices.
The following EDID features are copied from Output 1:
• Supported Resolutions
• 3D Support
• Audio Features
EDID color features are built based on all attached displays, using the
following rules:
• Deep Color will be enabled if one or more displays are connected to the
Splitter supporting Deep Color.
• xvYCC (x.v.Color) is supported if all connected displays support it.
Display Connections:
• If a display is not connected to Output 1, then no EDID changes are made,
meaning that the previous EDID information will be used. This state will be
in effect until a display is connected to Output 1 and the Splitter is power-
cycled.
• EDID is built from Output 1 to the Input. The audio block will be copied
from Output 1. EDID-copying is performed only when the Splitter is reset or
power-cycled.
