Optimize The Stereo Sync Delay - Christie Mirage User Manual

Note: If you are setting up Stereo 3D on a blended display, once the first projector is
set up, you will need to adjust the frame delay on all projectors to match the
projector to which the 3D Stereo Sync Cable is connected. Then fine-tune the frame
delay for each projector.

Optimize the Stereo Sync Delay

A proper Stereo Sync Delay setting can minimize cross-talk or ghosting. It is
available only if you are using the Mirage 3D Stereo Sync cable. When the
Stereo Sync Delay is incorrect, your projector display and monitor may show
very different images.
•
Using the projector screen as a reference, adjust the Stereo Sync
Delay so that the ghosting in the test pattern is equal with both eyes
(see below). Close one eye at a time to check and adjust.
Figure 10. Projector test pattern viewed through stereo 3D glasses
shows cross-talk of data for the opposing eye.
•
Using the monitor as a reference, adjust Stereo Sync Delay until the
image is no longer split. You may have to try adjustments in both
directions (increasing or decreasing frame delay) to determine which
results in a clearer image.
