The Gefen TV Mini 1:8 Splitter for HDMI 1.3
The Mini 1:8 Splitter for HDMI 1.3 is a compact and lightweight wall-mounted
alternative to our rack-mounted HDMI 1.3 splitters. The Mini 1:8 Splitter for HDMI
1.3 sends one source of HDMI digital high definition audio/video to 8 HDMI-com-
pliant displays at the same time. It supports all HDMI equipment such as DVD
players, satellite set-top boxes, and all HDMI displays. Features include transmis-
sion of high-def, deep color video resolutions up to 1080p@60 Hz combined with
advanced lossless digital audio formats for pristine sound reproduction.
How It Works
Connect your HDMI video source to the Mini 1:8 Splitter for HDMI 1.3’s input
using the supplied HDMI cable. Connect up to 8 HDMI-compliant displays to the
unit’s 8 HDMI outputs. Once connected and powered, the source signal will be
seen on all eight displays at the same time.
Note:
This Splitter will attempt to identify and configure connected displays by captur-
ing their EDID data (resolution/capability information that is unique to a particular
display). If EDID data is unavailable, the Splitter can use a pre-programmed
standard EDID that is compatible with most displays. A bank of 2 EDID function
switches on the front panel allows selection of EDID type (internal or external)
and 2-channel or multichannel audio.
All displays that cannot show the same video resolution(s) as the Primary Display
connected to Output #1 may fail to show a picture. Secondary displays follow the
Primary by sharing the resolution and capability information (EDID) obtained from
the Primary Display.

CONNECTING AND OPERATING THE MINI 1:8 SPLITTER FOR HDMI 1.3
How to Connect the Mini 1:8 Splitter for HDMI 1.3
1. Connect an HDMI source device to the HDMI input port on the Mini 1:8
Splitter for HDMI 1.3 using the INCLUDED HDMI cable.
2. Connect up to 8 HDMI capable devices to the output ports on the Mini 1:8
Splitter for HDMI 1.3 using USER supplied HDMI cables.
NOTE: Always connect one HDMI output device to output port 1 when using the
EXTERNAL EDID mode. Please read the Operation Notes (page 2) and EDID
Modes (page 6) for more information about EDID handling and routing.
3. Connect the included 5V DC power supply between the power input
receptacle and an open wall power socket.
How to Operate the Mini 1:8 Splitter for HDMI 1.3
The Mini 1:8 Splitter for HDMI 1.3 does not require any configuration to begin
splitting the incoming HDMI input signal. However, depending on the features
required by the user, the EDID Mode and Audio Channel Selection switches may
need to be adjusted. Please see the following section for more information on the
usage of these switches.
EDID Modes
The Mini 1:8 Splitter for HDMI 1.3 features automatic and manual EDID
adjustments to maximize compatibility of all attached devices. First it is
necessary to understand EDID and what it is used for.
EDID. What is it and what is it used for?
Under normal circumstances, analog (i.e. VGA computer) and digital (i.e. Bluray
player) source devices will require information about a connected device/display
to assess what resolutions and features are compatible. This required information
is read from a standardized file called the EDID (Extended Display Information
Data). Almost all types of output devices/displays (computer monitor, HDTV, A/V
receiver) will carry and transmit its EDID to a connected source. The source will
then read this EDID file and make the necessary adjustments to ensure that only
compatible features are released to the device/display. A source can only accept
and read one EDID from a connected device/display. Likewise, the source can
only output one resolution and audio type for a connected device/display to use.
Why is EDID so important with the Mini 1:8 Splitter for HDMI 1.3?
The Mini 1:8 Splitter for HDMI 1.3 is complex piece of technology that replicates
a single input signal to multiple outputs. The single source device will require one
EDID to read. Multiple devices/displays can be connected to the outputs on the
Mini 1:8 Splitter for HDMI 1.3, each with its own EDID, so management of this
information is key to ensure that maximum compatibility is maintained between
all devices.

EDID MANAGEMENT
What options do I have to manage the EDID in the Mini 1:8 Splitter for HDMI
1.3?
It is important to understand that the EDID contains much more than just listings
of supported resolutions and audio formats. However, resolutions and audio
formats are the two key types of information that a user will need to understand
how to use these EDID management functions.
Common problems that a user may encounter while using a splitter can be:
1. Video may not be visible on all output devices/displays.
(This usually caused by a device/display not being compatible with the
currently used output resolution.)
2. Audio may not be heard on all output devices/displays.
(This usually caused by a device/display not being compatible with the
currently used output audio format.)
These issues arise from resolution/audio incompatibilities between the different
devices/displays connected to the splitter.
The Mini 1:8 Splitter for HDMI 1.3 can use one of two sources to acquire and
transmit an EDID.
EXTERNAL MODE: This mode will use the EDID from the device/display
connected to the HDMI output port 1. All resolutions and audio formats
specified in this EDID will be passed to the source device.
NOTE: All other HDMI capable devices/displays connected to the other
output ports MUST be compatible with at least one resolution/audio format
supported by the device/display connected to HDMI output port 1. 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.
- To use this mode, set the EDID Mode Switch on the front panel to the EXT
position.
This mode should be used in scenarios where a particular resolution or
audio format is required by the output devices/displays.
3. INTERNAL MODE: This mode will use a preset EDID that is stored in the
Mini 1:8 Splitter for HDMI 1.3. All resolutions and audio formats specified in
this EDID will be passed to the source device. Many common resolutions
and audio formats are supported by this EDID. For a complete listing of the
resolutions and audio formats listed in this EDID please see page 9.

EDID MANAGEMENT
Continued from the previous page
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, 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.
-To use this mode, set the EDID Mode Switch on the front panel to the INT
position.
This mode should be used in most scenarios.
Audio Channel Selection
The Mini 1:8 Splitter for HDMI 1.3 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 Mini 1:8 Splitter for HDMI 1.3 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 9.
-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 9.
-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.

AUTOMATIC DEEP COLOR DETECTION
Automatic Deep Color EDID Features
The Mini 1:8 Splitter for HDMI 1.3 features an automatic EDID modification
feature that will evaluate all connected devices/displays for Deep Color
compatibility. Regardless of the selected EDID Mode, if an output device/display
that is connected does not support the HDMI 1.3 specified Deep Color feature,
all EDID Deep Color features will be removed. This will maximize compatibility
in a mixed output device environment. This feature is automatic and cannot be
disabled.
