Black Level Uplift
Black in the blended regions appears less dark than in the rest of the i\
mage.
Use this menu to raise black levels in the unblended regions to achieve \
a uniform 
black level.
Black level uplift is available for up to two edges, and they must be op\
posite each 
other. For example, you can set black level to To p and Bottom, or to Left and 
Right, but not to To p and Left.
1. Select Area
Stray light from the pond of mirrors of the DMD™ will elevate the bla\
ck level 
outside the blended regions. Adjust the slider to align the black level uplift 
area with the edge of the pond of mirrors. The possible values are 8, 16, 24 
and 32 pixels.
If required, adjust the opposite edge as well.
2. Adjust
Navigate to the Adjust group of settings and set All to the required amount of 
black level correction. This will apply equal correction to the black levels of all 
colors.
If necessary, use the individual color sliders for fine adjustment.
Notes
 Availability of black level area 
controls depends on settings in the 
Blend Width menu.
 Enable Align Pattern from the 
Edge Blend menu to see the black 
level uplift area.
 Black Level Uplift is unavailable 
when using any of the following 
settings from the

• Pincushion / Barrel

3D menu
Use this menu to enable, disable and set up 3D input, as follows:
• 3D Format — Off, Auto, Side by Side (Half), Top and Bottom and 
Dual-Pipe.
• DLP Link — On (if you are using 3D glasses that can utilise the DLP Link® 
signal embedded in the image) and Off
• 3D Swap — Normal and Rever se (set to Rever se if the left- and right-eye 
images are displayed in the wrong order)
• Dark Time — 0.65 ms, 1.3 ms, 1.95 ms and 2.5 ms. Set to reduce the 
effect of images overlapping while the glasses are switching
• Sync Offset — use the LEFT  and RIGHT  arrow buttons to compensate 
for signal processing delays in the projector.
Notes
 For further information about 
supported 3D formats, see 3D 
connections in the Connection 
Guide .
 If 3D Format is set to Off, or if 
no 3D signal is detected in 
Auto 
mode, the following settings will be 
unavailable:
• 3D Swap
• Dark Time
• Sync Offset
 Frame Sequential is supported on 
the DVI input only.
  3D video is only possible on the 
HDMI, HDBaseT and DVI inputs.
 The Frame Packing format is 
automatically detected by the 
projector.

settings explained further in this

3D types
In most situations you can use the Auto setting to have the projector automatically detect the 
format. Otherwise, consider the notes below to help you set up the 3D in\
put manually.
The following 3D formats are supported:
• Dual-Pipe (LEFT and RIGHT) 
The left and right eye images are delivered on two separate HDMI links, which the projector 
will interleave for 3D display.
• Frame Packing 
This format will be detected, re-synchronised, frame-multiplied and disp\
layed at 144 Hz with 
the left eye / right eye dominance automatically extracted from the video data. You need to 
optimize Dark Time and Sync Delay manually to suit your chosen switching glasses.
• Top and Bottom 
Sets the projector to reformat the video frames and map them to the display with the left eye / 
right eye dominance automatically extracted from the video data. You need to optimize Dark 
Time and Sync Delay manually to suit your chosen switching glasses.
• Side by Side (Half): interlaced and progressive, 50 and 60Hz 
The side-by-side image will be de-interlaced (if appropriate), resized and then sequentially 
displayed at 100 or 120 Hz.  The left eye / right eye dominance will be automatically extracted 
from the video data, however you will need to optimize Dark Time and Sync Delay manually 
to suit your chosen switching glasses.
Dark Time and Sync Delay need to be set only once, to optimize the image for the glasses in 
use.

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 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
  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 Offset time to eliminate 
ghosting and achieve a smooth 
grayscale.
3.  Repeat steps 1 and 2 until the best 
result is obtained.

Frame rate multiplication in 3D images
When displaying a low frame rate 3D video, the projector 
multiplies the frame rate to obtain a flicker-free image. For 
example, a 60Hz frame rate is doubled to 120 Hz, or a 48 Hz 
frame rate is tripled to 144 Hz.
Frame rate multiplication is an automatic process. It occurs in 
the background and cannot be modified by the user.
