Once all four decoders have been properly configured, the image will be correctly displayed across all four
displays. Refer to the illustration on the next page.

IMPORTANT:
When using dual-channel decoders, the
Rotation
feature can only be used when
a single HDMI channel is active. Image rotation is not supported on dual-channel decoders
when both HDMI channels are active. Single-channel decoders do not have this restriction.
