WHITE BALANCE
A secondary group labeled White Balance adds U Offset and V Offset controls (Figure 70).

adjust the U Offset, the change affects only the blue/yellow portion of the video signal.
o Rotate U Offset clockwise to shift the signal toward blue and counter-clockwise
to shift the signal toward yellow.

The V portion of the video signal carries the red and green color information. Adjusting
it affects only the red/green portion of the video signal.
o Rotate V Offset clockwise to shift the signal toward red and counter-clockwise
to shift the signal toward green.

The next tabbed pane in the Output Configuration panel may show controls for two distinct
outputs – Aux output (3Play™ 820 only) is a supplemental video output with the same set of
video connectors as Output A and B; Multiview supports a ‘multi-bridge’ or supplemental
monitoring layout connected by a DVI cable.
