Flow Chart 3: No Video Image (with Video LED illuminated on the TX)
What to Expect with Normal Video Display
On power up, the Video LED illuminates, turns off, and then illuminates indicating that the video signal is
present. On both DGX RX modules, the LED sequence for the Scaling LEDs is: all illuminate, all turn off,
and then the Auto LED illuminates as the video displays at the destination (assumes power up is in Auto).

Yes
> Check for correct input port
on monitor.
> Determine monitor’s supported
resolutions.
> Place RX in Manual and use
Scaler Override utility to use
one of the monitor’s supported
resolutions (start with native
resolution, and then try a
different one).
> Re-plug first one end of cable
and then other end.
> Use alternate input port on
monitor.
> See Technical Note on
“SmartScale ® and EDID
Behavior” at www.amx.com .
No
Important:
The Power LED can
illuminate solid amber at any time,
not just at power up. If this occurs,
check the error code (see page 62)
and contact technical support.
* EDID was not read. If monitor
does not support input resolution,
it will not display video. Typically
monitor will give indication that it
does not support parameters
provided.
Yes
Is Auto LED blinking
green and Bypass LED
solid green (Auto scaling
failure*) ?
