3D SETUP
Rev E August 2014
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
Normal
.
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 the
Dark Time
to a value
appropriate to the glasses or
ZScreen, say 0.65 ms
or 1.3ms
.
2. Adjust the
Sync Delay
time to
eliminate ghosting and achieve a
smooth grayscale.
3. Repeat steps 1 and 2 until the best
result is obtained.
