Using the External EDID

When set to Ext mode, the splitter will fetch the EDID data of each display (or other sink device) that is connected to the splitter. Once this information is gathered, the splitter “builds” an EDID based on the highest video resolution and most superior audio format that is supported by both sink devices. This EDID is then transmitted to the source device.

1.Disconnect the power supply from the splitter.

2.Set the EDID switch to the Int position.

Set to the Ext 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.
