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-ray 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. 6 EDID MANAGEMENT What options do I have managing 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 specifi ed 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. 7 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...
