Clock Timeline Sync is an alternative method to the previously mentioned Network Timeline Sync. The Clock Timeline Sync is less precise than the Network Timeline Sync, however, it can operate without a LAN cable connection between the projectors. Before using the Clock Timeline Sync make sure all projectors in the Group are set to the same timezone. (Lumiverse UI/Settings/Advanced/Internal Clock)

How to activate the Clock Timeline Sync
When switching the Lumiverse ON, un-check the Network Timeline Sync checkbox.
