The video wall settings are made on the "Zones" tab in the layers panel. Each zone is the part of the whole screen that the corresponding device will broadcast.
In order to expand one broadcast on multiple devices, you need to specify zones on the scenes of the project. Start with setting the project resolution equal to the total resolutions of all video wall screens (width/height) in the Project - Project Settings menu.
After that add the zones to the project.
The zone ID is required for the devices could identify the zones and reproduce the required broadcasting fragment.
Add the needed number of zones depending on the number of screens in the video wall/ Set the zone resolution parameters according to the parameters of the device, specify the ID of each zone and place it in the Addreality Player program when starting the advertising campaign.
You can clear the zones in the "Project - Project Settings - Zones" menu.
The program also provides the ability to export and import zones and their settings for use in other project templates (Import/Export zone settings).
