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.
