Some 3D settings explained
Dark Time
Ghosting can be caused by the left and right images overlapping
during the time that the ZScreen or 3D glasses are switching.
Dark Time
allows you to minimize this effect.
Source Dominance
The outgoing 3D frames are in pairs - the dominant frame being
presented first. You can determine which frame should be the
dominant one.
By convention the default setting is
Left
.
Sync Offset
The sync signal from the 3D server will be in phase with the frames generated by its graphics card. However, to compensate for processing
delays in the projector,
Sync Offset
introduces a delay to the sync output signal sent to the ZScreen or 3D glasses.

Notes
3D may not be present on some
models
In order to achieve maximum light
output and a smooth grayscale,
whilst eliminating ghosting,
the following procedure is
recommended:
1. Set the
Dark Time
to a value
appropriate to the glasses or
ZScreen, say 650
µS
or 1300
µS.
2. Adjust the
Sync Offset
time to
eliminate ghosting and achieve a
smooth grayscale.
3. Repeat steps 1 and 2 until the best
result is obtained.
