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.

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 

 for more information. 

 

1.  Disconnect the power supply from the splitter.

2.  Set the 

EDID switch 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. 

 

See Table 2.1 on the next page for specifications on the internal EDID.
