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.
EDID
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.

Troubleshooting
Problem Solution
How do I perform a
rmware update on
the AT-RON-442 / AT-
RON-444?
If updated rmware is available, both rmware and update

Does the Rondo
series provide external
automation control?
No.
3D content is not being
displayed.
• If using INT (internal) EDID mode, all connected displays
must be able to display 3D content. If only one of the
connected displays is not 3D-capable, then none of the
displays will show 3D content.
• To pass 3D content when not all displays support 3D,
connect a 3D display to Output 1, then use the “learn
EDID” procedure.
