Multi-screen canvas
Steps
- Open Settings → Canvas editor.
- Set canvas pixel size to your virtual stage (e.g. 3840×1080 for two 1080p projectors side by side).
- Add screens for each physical output window; position them on the canvas.
- Add layers sized/positioned where content should appear.
- Lock layers you do not want to nudge accidentally.
- Enable test pattern, align physical displays, then disable.
- Point video/text components at the correct layer ids.
