Sub-screens: split one screen into several

You switch sub-screens on in the settings of a screen: under Layout pick Sub-screens and click Configure sub-screens. Every sub-screen you draw there then shows up in Screens as its own row under the device, with its own schedule, its own content and its own reports. It stays one device with one pairing, and that is what the license covers too: sub-screens cost no extra screen license, however many you create.

Switching sub-screens on

Go to Screens in the sidebar and click the screen you want to split.
Open its settings and go to Advanced.
Under Layout, pick Sub-screens.
Click Configure sub-screens.

You can combine Sub-screens with Pixel Mapping under Output. The sub-screens then show only images and video, and you set the canvas to the Input resolution of the mapping. See pixel mapping.

Laying out the canvas

The configurator has two tabs: Screens for the sub-screens themselves, and Templates for ready-made layouts.

Templates holds eight layouts: 50/50, 70/30, 30/70, Thirds, Quadrants, L-shape, Picture-in-picture, and Free to start from scratch.

On Screens you add sub-screens with Add screen, rename them, and drag their edges to change position and size. There is no maximum number of sub-screens, and at least one is required. New sub-screens are named Screen 1, Screen 2, and so on.

The canvas is 1920x1080 with a black background by default. Click the resolution in the toolbar to switch between Full HD, Full HD Portrait, 4K, 4K Portrait and 720p, or type your own width and height, anywhere between 100 and 12000 pixels. The editor remembers 30 steps, so you can undo your way well back.

Click Save to lock in the layout.

How this differs from a split screen

A split screen is a content item: you build the layout with the content in it, save it in Files, and send it to a screen as one whole or drop it into a playlist. To change what plays in one area, you edit that item again.

Sub-screens are a property of the screen. Every sub-screen acts as a screen of its own, so you send content to it, schedule on it and report on it separately, without touching the other sub-screens.

Note that Screen Mirroring is not the same as a split screen. That is the app for sending your own picture live to a screen, see screen mirroring.

Sending content to a sub-screen

Open Files or Playlists and pick the item you want to show.
Choose Send to screen.
Select the sub-screen from the list. Sub-screens are listed with the device name in front of them, for example Reception screen - Screen 1.
Click Send.

A device that has been split can no longer be picked as a whole: for such a screen, the list shows its sub-screens only. You can, though, combine sub-screens from different devices with whole, unsplit screens in one go.

Each send covers a single item. Select several sub-screens and they all get that same item. Different content in different sub-screens therefore takes a separate action per sub-screen. There is more about sending in sending content to a screen.

Schedules, temporary content and reports per sub-screen

You link a schedule to a sub-screen the way you would to any other screen. Every sub-screen follows its own schedule.
Temporary content goes to a single sub-screen, without interrupting the other sub-screens, see temporary content.
In Reports, a device that has been split offers its sub-screens only, never the device as a whole. Sub-screens from different devices can go in one report, and an unsplit screen you pick as a whole.

Undoing the split

Open the settings of the screen.
Set Layout back to Whole screen.
Click Save and confirm.

All sub-screens are deleted. Right after you save, the device gets an instruction over the websocket and switches back to full screen. If that instruction does not arrive, the device picks the change up at its next heartbeat.

More per-screen settings are covered in screen settings.
