READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE GEFENTOOLBOX 1:4 SPLITTER FOR HDMI
• EDID contains the A/V capabilities of a display device in regards to video
resolutions and audio formats supported. This information is used by the
source device to determine the format of the A/V signal it outputs. The
GefenToolBox 1:4 Splitter for HDMI has advanced EDID management
features to ensure complete compatibility with all sources and display
devices. See pages 7-10 for more details.

EDID MANAGEMENT
EDID Mode Selection
1. EXTERNAL MODE:
See page 9 for details on using the External EDID.
2. INTERNAL MODE:
In Internal EDID Mode, a generic EDID is used for all connected devices.
This is useful when sufficient EDID data is unavailable from display devices
or EDID-related problems are encountered. The generic EDID is compatible
with most A/V equipment on the market.
Set the EDID Mode Switch on the front panel to the INT position. This mode
uses a standard, pre-programmed EDID at the factory which is compatible
with most A/V display devices. All video resolutions and audio formats
specified in this EDID will be passed to the source device. For a complete
definition of the A/V formats in this internal EDID please see page 10.
NOTE: All other HDMI-capable 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 a commonly supported
video resolution and audio format on the source device, to be shared by
all attached devices/displays. This is to ensure that a compatible signal is
output to all connected devices/displays.

EDID MANAGEMENT
Audio Channel Selection
The GefenToolBox 1:4 Splitter for HDMI features a switch that will modify the
supported audio formats listed in the pre-programmed EDID. This feature is
useful for limiting the output of the source device to either 2 or multi-channel
audio formats.
NOTE: This selector switch will only affect the pre-programmed EDID in the
INTERNAL (INT) EDID Mode.
The GefenToolBox 1:4 Splitter for HDMI can use either of the following settings
for audio format support:
1. 2 Channel: This setting will limit the audio formats listed in the pre-
programmed EDID to 2 channel LPCM. For a full listing of the audio formats
in this mode please see page 10.
To use this mode, set the Audio Selection Switch on the front panel to the 2
CH position.
This mode is useful in scenarios where all output devices/displays are HDTV
monitors that only support 2 channel LPCM. This setting will ensure that all
connected devices will receive and produce sound.
2. Multi-Channel: This setting will enable all common audio formats in the pre-
programmed EDID. For a full listing of the audio formats in this mode please
see page 10.
To use this mode, set the Audio Selection Switch on the front panel to the
Multi CH position.
This mode is useful in scenarios where the output devices/displays are
varying devices (i.e. HDTV display and audio receivers). Please note that
sound may not be heard from all output devices/displays if a shared common
audio format is not used by the source device.

EDID MANAGEMENT
External EDID Management
The GefenToolBox 1:4 Splitter for HDMI features EDID Management. Before the
source can send video or audio signals to the display, the source devices reads
the EDID (Extended Display Identification Data) of each device connected to
an output. The EDID contains information about what type ofA/V data that the
source can send to each display.
GefenToolBox 1:4 Splitter for HDMI 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.
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 copied from Output 1 to all other outputs. The audio block will be
copied from Output 1. EDID-copying is performed only when the Splitter is
reset or power-cycled.
3DTV Support
• 3D signals are supported if a 3DTV is connected to Output 1.
Deep Color
• Deep Color will be disabled if one of more other displays connected to the
Splitter do not support Deep Color.

FAST SWITCHING TECHNOLOGY
Fast Switching Technology
Fast Switching Technology (FST) is a Gefen software implementation for
HDMI 1.3 products. FST was created to improve the inherited lengthy HDMI
authentication process, based on the HDMI and HDCP specifications.
FST provides quickerA/V source switching and greatly improves the overallA/V
system behavior and performance when more than one HDTV display is used in
the system setup.
FST allows connecting / disconnecting or turning ON / OFF of HDTV displays
without having these activities affect other Hi-Def sources routed to any other
HDTV display in the same system.

WALL MOUNTING INSTRUCTIONS
The GefenToolBox 1:4 Splitter for HDMI should be mounted vertically in a wall or
cabinet with wood/drywall screws as shown in the diagram above. There should
be an inch or two of clearance between the edges of the unit and any walls or
vertical surfaces to allow for enough clearance for insertion and retraction of
cables at the HDMI connectors.
For installation on a drywall surface, use a #6 drywall screw. It is recommended
when installing on a drywall surface that studs be used to secure the Splitter
should undue stress be applied when connecting and disconnecting HDMI
cables.
