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.
3D Swap
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 Delay
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 Delay
introduces a delay to the sync output
signal sent to the ZScreen or 3D glasses.

Notes
In order to achieve maximum light
output and a smooth grayscale,
whilst eliminating ghosting,
the following procedure is
recommended:
1. Set
Dark Time
to a value
appropriate to the glasses or
ZScreen, say 1 ms
or 1
.5
ms
.
2. Adjust
Sync Delay
time to eliminate
ghosting and achieve a smooth
grayscale.
3. Repeat steps 1 and 2 until the best
result is obtained.
