Device Operation
The following diagram will be used to illustrate how to configure a 2 x 2 video wall. The details of this diagram are
listed below:
• Four decoders are subscribed to a single encoder. Each decoder is connected to a display.
•
The encoder is transmitting a 3840 x 2160 video signal.
•
The top two displays have been accidentally mounted upside down.

This diagram presents some challenges that need to be met:
a.
Since there are four displays, the image from each decoder will need to be scaled to one-fourth of the total
resolution. The crop-and-scale feature will be used to provide the correct output.
b.
The top two displays have been mounted upside-down. To meet this challenge, the rotate feature will be applied
to these two displays.
