KRAMER:  SIMPLE CREATIVE TECHNOLOGY

 

Using the VM-24HC 2 Input 1:4 HDMI Distributor 

 

The EDID

1

 can be acquired from: 

 

One output  

 

The default EDID  

 

Up to four connected outputs using the Auto-mix Mode

2

  

Repeatedly pressing the EDID SELECT button cycles through the EDID 

sources in the following order

3

 

Output 1 (Output 1 LED lights) 

 

Output 2 (Output 2 LED lights) 

 

Output 3 (Output 3 LED lights) 

 

Output 4 (Output 4 LED lights) 

 

Default EDID (all LEDs light) 

 

Auto-Mix EDID (the LEDs flash in a running sequence) 

To store the selected EDID, press EDID READ as described in the 

following example

4

.   

To select the EDID from Output 3:  

1.  Press the EDID SELECT button repeatedly until OUTPUT 3 LED lights.  

2.  Press the EDID READ button. 

When the LED stops flashing the EDID from Output 3 is stored at the input.  

Pressing the EDID SELECT button briefly once causes the relevant LEDs 

to indicate which EDID is stored at the input as follows: 

 

OUTPUT 1 LED flashes—the EDID from OUTPUT 1 was the last acquired 

 

OUTPUT 2 LED flashes—the EDID from OUTPUT 2 was the last 

acquired, and so on  

 

All OUTPUT LEDs light—the default EDID was the last acquired  

 

All OUTPUT LEDs flash sequentially—the Auto-Mix

2

 EDID was the 

last acquired  

 
 
 
 
 

                                                       

 

1 This is usually done only once when the machine is being set up in an installation. Once acquired, the EDID is saved in non-
volatile memory and further acquisition is not necessary 
2 The EDID acquired is a weighted average of all the connected outputs. For example, if several displays with different 
resolutions are connected to the outputs, the acquired EDID supports all the resolutions, as well as other parameters included 
in the EDID 
3 If you attempt to acquire the EDID from an output that is not connected the default EDID is acquired 
4 To cancel the EDID modification wait for a few seconds without touching any button
