6.3.5 Synchronization Adjustments

Synchronization Adjustments
It is possible to adjust the synchronization in
Computer mode by adjusting the Phase and
the Frequency. The synchronization will be set
by the automatic set-up function. Manual sync
adjustments should typically not be required.
The setting will follow the source, which
means that you can have different settings for
video and computer. The pre-defined settings
will also vary with the source.

All maintenance should be done

by Zenith authorized service

personnel. Contact Zenith at
