EDID MANAGEMENT

Understanding EDID

The GefenToolBox 1:8 Splitter for HDMI with FST 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. Blu-rayplayer) 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 GefenToolBox 1:8 Splitter for HDMI with FST?

The GefenToolBox 1:8 Splitter for HDMI with FST is a 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 GefenToolBox 1:8 Splitter for HDMI with FST, each with its own EDID, so management of this information is key to ensure that maximum compatibility is maintained between all devices.

What options do I have to manage the EDID in the GefenToolBox 1:8 Splitter for HDMI with FST?

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.

2.Audio may not be heard on all output devices/displays.

These symptoms usually arise from video resolution / audio format incompatibilities between the devices / displays connected to the splitter.

The GefenToolBox 1:8 Splitter for HDMI with FST can use one of two methods to acquire and retransmit an EDID to the A/V source device telling it about

the kind of output devices that are connected to the Splitter, thus curing the incompatibility.

EDID MANAGEMENT

EDID Mode Selection

1.EXTERNAL MODE:

To use this mode, set the EDID Mode Switch on the front panel to the EXT position. In External EDID mode, the Splitter directly retrieves EDID data from each connected A/V display device and builds a new EDID created from the highest common video resolution that all display devices can use together and the highest audio capability. This new EDID is sent back to the source device.

If sufficient EDID data is unavailable from external display devices or EDIDrelated problems are encountered, Internal EDID Mode should be used to provide a single compatible EDID for all connected devices.

2.INTERNAL MODE:

To use this mode, set the EDID Mode Switch on the front panel to the INT position. This mode will use a preset EDID that is stored in the GefenToolBox 1:8 Splitter for HDMI with FST from the factory. Thispre-programmedstandard EDID data structure is compatible with most A/V display devices. All resolutions and audio formats specified in this EDID will be passed to the source device. For a complete listing of the resolutions and audio formats listed in this EDID please see page 11.

NOTE: 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.

EDID MANAGEMENT

Audio Channel Selection

The GefenToolBox 1:8 Splitter for HDMI with FST 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 or multichannel audio formats.

NOTE: This selector switch will only affect thepre-programmedEDID in the INTERNAL (INT) EDID Mode.

The GefenToolBox 1:8 Splitter for HDMI with FST 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 11.

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 preprogrammed EDID. For a full listing of the audio formats in this mode please see page 11.

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 (e.g. 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 1:8 Splitter for HDMI with FST 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 of A/V data that the source can send to each display.

The 1:8 Splitter for HDMI with FST 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 powercycled.

EDID is copied from Output 1 to all other outputs. The audio block will be copied from Output 1. EDID-copyingis performed only when the Splitter is reset orpower-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

FASTSWITCHINGTECHNOLOGY

Fast Switching Technology

Fast Switching Technology (FST) is a Gefen software implementation for HDMI 1.3 products. FST was created to improve the inherent lengthy HDMI authentication process, based on the HDMI and HDCP specifications.

FST provides quicker A/V source switching and greatly improves the overall A/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-Defsources routed to any other HDTV display in the same system.

FAST MODE:

Setting the Splitter to FAST mode will improve performance when connecting / disconnecting Hi-Defsources, and powering ON / OFF HDTV displays.

NOTE: When switching from SLOW mode to FAST mode, the HDTV displays connected to the Splitter will blink momentarily.

SLOW MODE:

When set to SLOW mode, the Splitter will follow the standard authentication process, based on the HDMI and HDCP specifications. SLOW mode is recommended when the source does not support multiple devices.

WALL MOUNTING INSTRUCTIONS

The GefenToolBox 1:8 Splitter for HDMI with FST 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.
