1.0 INSTALLATION

1.0 INSTALLATION
1.1 The optional BEST 3D passive Kit
Dreamvision projectors are now available with a 3D passive modulator for 3D enthusiasts and spectators how are
3D sensitive. Thanks to the use of the passive 3D technology and the lightweight, flicker-free glasses, the
stereoscopic picture is 50% brighter than with the active sets but also smoother and more natural to the eyes. The
BEST 3D passive Kit is installed in front of the projector. Avoid direct sun light and make sure to install it in a place
with a good ventillation.
Make sure to have a passive 3D compatible screen installed before proceeding to the BEST 3D passive Kit install.
To make the installation easier, use this guide together with the original Dreamvision Passive 3D Test Patterns
package available on www.dreamvision.net.
1.2 Download the BEST 3D passive Kit setup TEST PATTERNs
This manual refers to TEST PATTERNs that can be downloaded directly from the official BEST 3D passive Kit web
page, in the download section. These patterns are in PNG format and they may be used in addition to this document
to make easier and faster the install.
If you choose to use these TEST PATTERNs, you will need to display them at 1920x1080 pixels resolution on the
projector. To do so, you probably can load them on a USB key directly inserted into your Blu-Ray player or simply by
connecting a computer to the projector, using a DVI to HDMI cable.
1.3 Passive 3D screen that maintains light polarization
In order to enjoy the best quality 3D images, you need a polarization preserving screen. Such a screen is generally
called “silver screen” and it is specially designed for 3D projection. Dreamvision has developed and optimized a
special screen fabric for both 2D projection and passive 3D projection: the “Passive 5D screen”. It is a low gain and
high extinction ratio fabric that you can order together with your BEST 3D passive Kit.
1.4 Attach the BEST 3D passive Kit to the projector
a) Use the 2 wheels to attach the Modulator to the U-shape support.
Fix the Modulator to the U-shape support using the 2 wheels.
Visit Dreamvision’s web site: http://www.dreamvision.net to download the TEST PATTERNs.
If your screen is not manufactured and tested for passive 3D use, you might experience uncomfortable and
blurry 3D images with a high level of crosstalk, which will greatly impact on the perception of the
stereoscopic effects.

2.0 POSITION AND ALIGNMENT
2.1 STEP 1: Adjust the 3D passive modulator gross position
Position the projector equipped with the BEST 3D passive Kit at the desired projection distance. Then adjust the
correct zoom, offset and focus to fit the screen. These adjustment are made by using the Zoom, Focus and the
vertical / horizontal Shift of the projector.
Adjust the lens Offset and Zoom until the picture fills the screen.
Adjust the picture Focus
Once the picture is correctly centered and fills the screen, please use the TEST PATTERN 1b (full green pattern
with 16:9 written on it) to adjust the modulator correctly in front of the projector lens. The correct position for the
modulator is reached when the light path uses the maximum surface of the LCD window, without blocking light in
the borders. To do so, place the BEST 3D passive Kit at the maximum distance possible and moves it toward the
projector until the light path is centered and entirely contained into the LCD window.

Tighten the 2 screws A when the distance between the modulator and the projector lens is correct.
Then adjust the vertical position to center the light path into the BEST 3D passive Kit as described below.
Tighten the 2 wheels B when the light path is at the center of the modulator.
If the projector uses a large zoom (<2.0 throw ratio distance), the modulator will be fixed nearer to the
projector. If the projector uses a small zoom (>2.0 throw ratio distance), the modulator will be located farther
from the projector.

2.2 STEP 2: Moiré artifacts and Focus
Depending on the size of the screen, the screen fabric may -or may not- interact with the projector pixels and
develop some color banding interferences. In order to remove them completely, you may alter slightly the projector
focus. Use the TEST PATTERN 2b or a bright picture (White, Cyan by example) to set the correct projector Focus..
Alter slightly the picture focus to eliminate the moiré artifacts.

2.3 STEP 3: Vertical and Horizontal Tilt setting (important)
Ideally, the BEST 3D passive Kit should be perfectly perpendicular to the light path, that means if you use the
projector offset to center the picture into your screen, you will need to set an initial tilt on the 3D passive modulator.
Set the initial tilt of the BEST 3D passive Kit perpendicularly to the light path.

Lens Flare
Also, due to internal reflections from the 3D passive modulator, you may see a noticeable lens flare on high contrast
pictures, typically credits at the end of a movie, or using TEST PATTERNS 3a and 3b.
Use TEST PATTERN 3a to check if there is a ghosting text at the top and bottom of the screen.
To completely remove Lens Flare, apply an additional Vertical and
Horizontal tilt to the modulator. These additional tilts should not exceed 7°.
Use TEST PATTERN 3b to perfectly identify the lens flare location.
To completely remove the lens flare, tilt the BEST 3D passive Kit in order to change the lens flare position and to
move it out of the screen. Preferably move it outside the screen through one of the four circles number 8, 13, 78 or
83. To do so, you will apply a vertical tilt and horizontal tilt. This step is required to obtain a ghost free and highly
contrasted picture.
It is recommended to always use a small amount of tilt to remove the potential reflections, called lens flares.
Do not use more than 7° of tilt. Above this mark, there is too much tilt and a visible vertical ghosting will
appear and may distract spectators.
The lens flare may be identified as a very bright, disc-shaped reflection of a portion of the original picture as
shown in the above picture. By changing the BEST 3D passive Kit tilt, the lens flare will move around the
picture and be more noticeable.

2.4 STEP 4: Check the 3D performances
To check the 3D performances of the BEST 3D passive Kit, you can use TEST PATTERN 4b or directly by viewing a
3D program. To use the TEST PATTERN 4b, please follow the steps below:
• Browse, select and display the TEST PATTERN 4b
• Go into the projector menu and select the Side-by-Side 3D mode
• Put the passive 3D glasses on
When closing the right eye, the R-squares should be barely visible.
2.5 STEP 5: Ghosting Black-over-White levels (optional)
The TEST PATTERNS 5a and 5b will reveal the ghosting overlapping black-over-white level. This setting has a
minor performance hit on global 3D performances. Additionally, if the lens flare has been correctly pushed out of the
screen, there should be only a residual clear coloration into the black pattern.You can adjust into the projector menu
the black level and white level to reduce the overlapping coloration.
Make sure when doing this setting that the central steps remain in grey shades.
The overlapping black-over-white may be lightly colored but
the central bar must remain in grey shades to obtain the best 3D performances.
Note that the projector needs to warm up at least 20 min. to obtain a cross-talk free image.
Once STEP 5 is completed, you can set in the projector menu the 3D mode back to “Auto”.

4.0 MAINTENANCE AND CLEANING
Avoid direct sun light and water contact with the BEST 3D passive Kit. This device must be in a place with good
ventillation. Clean the BEST 3D passive Kit lens periodically, or whenever you notice smudges or too much dust on
the crystal surface.
•To remove dust or smudges, gently wipe the lens with a dry and soft lens cleaning cloth.
•To remove stubborn smudges, moisten a lens cleaning cloth with lens cleaner and gently wipe the surface of the
lens.

ISSUE SOLUTION
LED is not light up Ensure that the VESA > JACK cable is correctly inserted and that the
projector is not in standby mode.
Red is continuously light The BEST 3D passive Kit is powered but cannot detect a 3D signal.
Please check that the projector is correctly set to 3D Mode (Frame
Packing, Side by Side or Top and Bottom in the info menu).
Green LED flashes correctly
but no 3D images are visible.
Ensure that the BEST 3D passive Kit is mounted in the correct
direction: the Dreamvision logo on the modulator must be visible. Make
sure that you wear the passive 3D glasses and that your screen is 3D
capable.
Avoid touching the lens surface directly to prevent finger prints or to damage the lens surface.
Avoid absolutely any water or humidity to accumulate into this device, otherwise the lifetime will be greatly
reduced. Make sure that this device is completely dry before lightning up the projector.
