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.
