3D Operation of Mirage Projectors

Images generated from a stereo 3D video source consist of a series of images or frames that
alternate quickly between two slightly different viewpoints, corresponding to our left and right eyes.
When these frames are displayed fast enough and viewed with special glasses synchronized to the
left or right changes, the resulting image appears to have the same depth and perspective as
reality.
To display stereoscopic 3D video, you must connect the Mirage WQ-L projector to additional
hardware such as stereo emitters and glasses. The type of 3D glasses can be active or passive
depending on the type of stereo controller and screen used.

3D System Timing

When configuring the projector for 3D operation, consult the documentation for your glasses or
polarization filter and keep their specifications in mind. The projected video must be optimized for
the glasses' shutter speed or polarization filter performance to prevent "ghosting" of the video
content (known as cross-talk in stereo 3D applications) or other more subtle color artifacts. Visual
performance can be optimized by adjusting the Dark Interval and the 3D Sync Delay settings.

3D Input Video Configurations

The stereo 3D input video stream is sent from the content server to the projector using 3D direct or
dual-input.

3D Frame Doubled Input

3D Frame Doubled Input will be available with Mirage WQ-L software release 1.2.1.
The Mirage projector supports a WQXGA 60Hz (30 Hz per eye) video input over a single DVI-D
cable. In this configuration a single video stream is provided by the video server, with the left eye
and right eye frames supplied as alternate frames. The display is frame doubled by the projector
resulting in 120 Hz projection. A 3D Input Sync must be used to identify the left eye frames.

3D Dual-Input 120Hz native output

The Mirage projector supports two WQXGA 60Hz video inputs, with the left eye frames supplied by
one video input and the right eye frames supplied by the other. The video streams must be frame
locked and supplied concurrently. The 3D dual-input video streams are supplied by two DVI Dual
Link connections.

3D Requirements

To control the projector's processing, synchronization, and display of the stereoscopic 3D source
material, stereo 3D applications require a stereo 3D-capable source, special hardware and
software, and the settings of the projector.
