5.4 EDID Setting
The Extended Display Identification Data (EDID) is used for the source device to match
its video resolution with the connected display. By default, the source device obtains its
EDID from the first connected display. Meanwhile, since the displays with different
capabilities are connected to the switcher, the 4-pin DIP switch on the rear panel can
be used to set the EDID to a built-in fixed value. Use the following table to determine
the setting for the 4-pin DIP switch for specific video resolution and audio capabilities.
The switch represents “0” when in the lower (OFF) position, and it represents “1” while
putting the switch in the upper (ON) position.
