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-mountedalternative to ourrack-mountedHDMI 1.3 splitters. The Mini 1:8 Splitter for HDMI 1.3 sends one source of HDMI digital high definition audio/video to 8HDMI-com-pliant displays at the same time. It supports all HDMI equipment such as DVD players, satelliteset-topboxes, and all HDMI displays. Features include transmission ofhigh-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-compliantdisplays 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 capturing their EDID data (resolution/capability information that is unique to a particular display). If EDID data is unavailable, the Splitter can use a pre-programmedstandard 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) and2-channelor 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.

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 portsMUST 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 portsMUST 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.

-Touse this mode, set the EDID Mode Switch on the front panel to theINT 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-programmedEDID. This feature is useful for limiting the output of the source device to either 2 ormulti-channelaudio formats.

NOTE: This selector switch will only affect thepre-programmedEDID 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 preprogrammed EDID to 2 channel LPCM. For a full listing of the audio formats in this mode please see page 9.

-Touse this mode, set the Audio Selection Switch on the front panel to the2 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 thepre-programmedEDID. For a full listing of the audio formats in this mode please see page 9.

-Touse this mode, set the Audio Selection Switch on the front panel to theMulti 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.
