Play 1 Video on Multiple Displays
This guide covers two ways to play a single video on multiple physical displays in Backstage:
-
Display Matrix — one Display spans across several outputs as one seamless canvas. Use this when all displays should show different regions of the same video (e.g. a wide panorama across three monitors).
-
Independent Displays — each display has its own sequencer playing the same asset. Use this when each screen should show the full video independently.
Option A: Display Matrix (one video spanning multiple outputs)
1. Add a Display to the Scene
Open the Scene window. Right-click the scene hierarchy and select Display → Plane.
2. Assign your video to the Display
Drag your video asset from the Assets window onto the Display. Confirm the Create Sequencers? dialog.
3. Enable Display Matrix
Select the Display. In the Inspector, find Display Matrix and enable it. Set Rows and Columns to match your physical screen arrangement:
|
Layout |
Rows |
Columns |
|---|---|---|
|
3 monitors side by side |
1 |
3 |
|
2x2 grid |
2 |

|
4 screens vertical stack |
4 |
1 |
4. Route each tile to a GPU output
In the Outputs window, assign each Display Matrix tile to its corresponding GPU output.
Option B: Independent Displays (same video on each screen)
1. Add a Display for each screen
Right-click the hierarchy and select Display → Plane once for each physical screen. Name them clearly.
2. Assign the video to each Display
Drag the same video asset onto each Display. Each gets its own sequencer referencing the same asset file.
3. Route and start playback
In the Outputs window, assign each Display to its GPU output. Use a single Control:LoadBang connected to all sequencer play inputs to trigger them simultaneously on project load.

Common Mistakes
-
Display Matrix tiles appear in the wrong physical order — tiles are numbered left-to-right, top-to-bottom. Re-route each tile to the correct GPU output.
-
Independent displays fall out of sync — each sequencer has its own trigger timing. Use a single LoadBang connected to all play inputs.
