Some 3D settings explained
Dark Time
Banding can be caused if the image is displayed before
each eye of the 3D switching glasses or ZScreen is
not fully open. Dark Time allows you to minimize this
eff ect.
Eye Swap
The outgoing 3D frames are in pairs - the dominant
frame being presented fi rst. 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 switching delays in the glasses or
ZScreen, Sync Offset is used to adjust the sync output
signal sent to the ZScreen or 3D glasses to minimise
overlapping (ghosting in the image when viewed
through the 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 1.3 ms or 1.95 ms.
2. Adjust Sync Off set time to eliminate
ghosting and achieve a smooth
grayscale.
3. Repeat steps 1 and 2 until the best
result is obtained.
