What is Active Stereo?
Field sequential 3D (also known as active 3D or
“
Active Stereo
”
) is a technique of displaying stereoscopic 3D
images. It works by only presenting the image intended for the left eye while blocking the right eye's view, then
presenting the right-eye image while blocking the left eye, and repeating this so rapidly that the interruptions
do not interfere with the perceived fusion of the two images into a single 3D image.
This system setup uses liquid crystal shutter glasses (also known as active shutter glasses). Each eye's glass
contains a liquid crystal layer which has the property of becoming opaque when voltage is applied, being
otherwise transparent. The glasses are controlled by a timing signal that allows the glasses to alternately
block one eye, and then the other, in synchronization with the refresh rate of the screen. The timing
synchronization to the video equipment may be achieved via a wired signal or via wireless communication,
this by using either an infrared or radio frequency (e.g. Bluetooth, DLP link) transmitter.
Projection method used
This projector can only show active 3D images, used in combination with a 3D emitter and active shutter
glasses. While it is allowed to connect passive stereo source signals, the image processing of the projector
will convert those signals to an active 3D compatible image.
The options on the projector software allow you to fine-tune the 3D settings accordingly to the specifications of
the 3D emitter.
If a 3D emitter is used that radiates IR beams, the IR beams may interfere with the IR
communication between projector and the RCU. If such interference occurs, connect the RCU to
the projector using the remote cable. It is also advised to turn the IR receivers on the projector off to
avoid the 3D emitter interference. To turn off the IR receivers, see

8.8.2 Setup process 3D projection
How to setup 3D projection?
1.
Connect the proper source cables to the projector. For more info, see
, page 99.
2.
Set up and connect your 3D emitter to the projector. For more info, refer to the user manual of your 3D emitter.
3.
Power on the projector completely.
4.
Select the correct stitched source Input in the Source menu. See
“
Displaying multiple sources: Stitched
”
, page 58.
5.
Select the desired Display format. For more info, see
Choosing the desired Display Setup
”
6.
Depending on the chosen 3D emitter, correct the 3D setup. For more info, see

8.8.3 Connection possibilities
At this moment, the only inputs supporting 3D on the Pulse input boards are the DisplayPort inputs
and HDMI input. More inputs may support 3D in a future release.
Connecting with the quad combo input card
There is only one way of projecting Active stereoscopic 3D with the Combo input card, using the following
setup:
•
Source
: Active Stereo (sequential L/R)
•
Layout mode
: Standard layout (1x1 layout)
•
Video Timing
: 2560 x 1600 (WQXGA) @120 Hz
•
Color depth
: 30 bpp
•
Connector
: DisplayPort 1.2 or HDMI
Connecting with the quad DP 1.2 Input card
You can use one of the following methods. The resulting image will always be an Active Stereo image.
