12.2 AS3D synchronization best practice

General
System complexity is naturally increase when the installation consists of multiple channels. If the system is not designed correctly
or the individual system components are not configured correctly, image artifacts will occur; or the image might not be displayed at
all. A very important aspect of planning any multi-channel installation is how to synchronize the projected channels.
When in AS3D it is impossible to obtain realistic 3D imagery if the projectors and projected images are not perfectly synchronized
as the left eye information and the right eye information will be slightly different.

Consider the setup shown above. This is a typical dual head 3D setup where each projector channel is driven by two individual
Image Generators (IG). The problem is that the IG are not in sync with each other. Each projector will synchronize its projected
image with one of the DVI inputs. Frame rate conversion will be applied to the other input as necessary but the two projectors will
not be in sync with each other. The preferred way to synchronize the projected images is to synchronize the IG. This is the only way
all image artifacts may be eliminated from the resulting image and is true for all projector brands; not only Barco projectors. If, for
some reason, one chooses to have asynchronous IG then extra synchronization must be performed by the projectors and while an
excellent 3D experience is obtained this way, there will be motion artifacts in the resulting image. Troubleshooting AS3D multichannel
installation issues, and in particular source synchronization issues, can be done using the Status menu. See "Troubleshoot source
sync issues", page 102 for more information.
