Setting the Edid Mode

Operating the 1:8 Splitter for HDMI 4K x 2K

The 1:8 Splitter for HDMI 4K x 2K features EDID Management. Before the source can send video and/or audio to the display (sink), the source reads the EDID (Extended Display Identification Data) from the display (sink) devices connected to the splitter. The EDID contains information about what type of audio/video data that the source can send to each output device. The splitter can use either the downstream EDID (from the display/sink) or the built-in internal EDID.

Using the Internal EDID

Use this EDID mode if problems are encountered when using the external EDID.

The built-in internal EDID provides the source device with a “generic” EDID which can be used by all display (sink) devices. The use of the internal EDID also provides control

of the audio output format. See Setting the Audio Channel Mode for more information.

1.Disconnect the power supply from the splitter.

2.Set the EDID switch to the Int position.

Set to the Int position

3.Reconnect the power supply.

If the EDID switch is moved from the Ext position to the Int position while the splitter is powered, then power-cycle the splitter by disconnecting and reconnecting the power supply in order for the change to take effect.
