You may access Group Control after the Group of Projectors has been created. You will find the Group Control your Lumiverse home screen (my.lumiverse.com) The Group Control appears as a link, starting with the capital letter G-. You can tell you’re in Group Control when you see the blue house symbol in the top left corner of the interface. 

What can Group Control do?
The Group Control is a special Lumiverse UI, that sends commands simultaneously to all projectors in the Group. Group Control can simultaneously switch between Projects. The Group Control can create and edit Projects and switch the Lumiverse Projection On/Off. You can create group schedules. The rest of the functions are controlled in the devices locally.

Important Note: We recommend managing Projects from Group Control, rather than individually in each projector. In order for the Image Synchronization to work, the name of the Project needs to be the same on all devices. If you experience troubles with Image Sync within a Group, make sure that the current project name is the same on all devices.
