Digital Projection Ltd. Titan Laser WUXGA

Some 3D settings explained

In order to achieve
maximum light output and
a smooth grayscale, whilst
eliminating ghosting, the
following procedure is
recommended:

Set

Dark Time

to a

value appropriate to the
glasses or ZScreen, say
1.3 ms or 1.95 ms.

Adjust

Sync Offset

time

to eliminate ghosting and
achieve a smooth
grayscale.

Repeat steps 1 and 2

until the best result is
obtained.

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 effect.
