EDID Control Settings

At times, your HDMI sources and display may not synchronize properly.  
This is when EDID* control should be utilized.  KD-HDSW switchers 
feature an internal library of default settings that modify KD-HDSW input 
port’s EDID to ensure that your HDMI source’s output is compatible with 
your display.
