Set up a multiscreen display

A multiscreen display treats several physical screens as a single virtual canvas — ideal for video walls. One screen is designated the primary and drives playback timing; the other member screens each render their slice of the canvas in synchronisation.

Key concepts

• Primary screen — the leader, always at position 0. It coordinates playback timing across all screens.
• Secondary screens — up to 5 additional screens (6 total maximum), attached with a grid position (row and column).
• Layout type — how the screens are arranged.

Layout types

Layout	Arrangement	Max screens
row	Side by side horizontally	1 row × N columns
stacked	Stacked vertically	N rows × 1 column
grid	2×2 grid	4
grid_2x3	2 rows × 3 columns	6
grid_3x2	3 rows × 2 columns	6

Create a multiscreen display

1. Go to Multiscreen Displays and click New Display.
2. Name the display and choose a layout type.
3. Select a primary screen.
4. Select the secondary screens to include.
5. Save. The platform automatically:
   • Calculates grid positions for each screen.
   • Creates a multiscreen playlist with a sub-playlist per screen.
   • Copies any existing content assignments into the multiscreen playlist.

Add content

When you add media to a multiscreen playlist, the platform:

1. Calculates the content's dimensions (for example, 1920×1080).
2. Determines the fit mode (cover for video, contain for images by default).
3. Computes per-screen transforms — scale and offset for each screen's slice of the canvas, including letterbox compensation.
4. Stores those settings on each screen's copy of the item.

Each screen in the wall then renders its own portion, and together they form one cohesive image or video across the whole canvas.

Manage the display

• Reorder screens within the display.
• Enable/disable the display without losing its configuration.
• Publish / republish the configuration to the screens.
• Compatible-screen detection helps you pick screens that work together.

Synchronisation

The primary screen drives timing and triggers play/advance commands to the secondary screens over a real-time connection, so playback stays in lockstep across the wall. Member screens report their readiness back to the primary before playback begins.

Next steps

• Publish the multiscreen configuration.
• Explore Screen Sync for synchronised playback across separate screens.
