Forcing the RGB Mode 

Normally (the default state), when acquiring the EDID, the device supports any color space 
that is defined in the acquired EDID parameters. In case of a color space problem, using the 
Force RGB mode may improve the colors of the image on the display. 

To 

Do the following: 

Force the acquired 
EDID to support only 
RGB color space:

  

Press and hold the EDID button for few seconds until all the output LEDs flash 
together four times.  
Continue to acquire the desired EDID.  
This acquired EDID is then forced to support the RGB color space only. 

Return to the normal 
EDID mode

:  

Press and hold the EDID button for few seconds until the output LEDs flash 
together once. 
Continue to acquire the desired EDID. 

View the force RGB 
activation status

:  

Power cycle the unit.  
All output LEDs will flash together once when in normal EDID mode, and four 
times when in Force RGB mode.
