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.
