Adjustment procedure in over / under configuration.
For Blend adjustments in over / under configuration, the procedure is the same as for side by side, but use the
Top and Bottom height instead, and perform a similar procedure.
Use the numeric keys instead of the arrow key to set the values.
Instead of adjusting the lines by the arrow keys, the value can also be typed directly using the numeric keys on
the remote control.
To remove or undo the entered numbers, use the * key on the remote control.
8.5.5 Black level setup procedure
Black level introduction
The Purpose of the black level adjustment is to adjust the black levels in the non overlapped areas with the
black level in the overlapped areas (Blend Zone).
This is a necessary function, due to the fact that the black level will be brighter in the blend zones, since
multiple projectors will add light in these zones.
The width of the black level area shall ideally be slightly larger than the width of the blend zone in order to also
compensate for the “sea of mirrors” phenomenon.
The figure below shows how this occurs in a side by side configuration without any correction of the black
level.
