The AT-RON-442 and AT-RON-444 provide two EDID modes: internal (INT) and LEARN. Internal
mode selects the highest common resolution and audio between the source and all displays.
LEARN mode will copy the EDID information of the display/sink connected to the HDMI OUT 1
port.
To switch between internal and learn modes, press and hold the EDID button. While EDID is
being learned, the LEARN LED will blink. EDID learn is complete when the LEARN LED goes
solid.

NOTE: 4K, 3D, and multichannel audio may not be available when using INT
(internal) EDID mode. When using this mode, the AT-RON-442 / AT-RON-444
will build an EDID, based on the capabilities of each display that is connected.
