OutputsScreens and canvas
Projectors, LED walls and capture.
Every connected screen, projector or LED processor can be an output. OUTPUT lists them with their resolution; Open as output puts a full-screen window on it. All outputs share one clock, so they stay in sync.

- Screens: every connected screen, projector and LED wall.
- Open as output / Close: one click per screen.
- Arrangement: same picture on all, canvas, or projection mapping.
- Canvas: drag the screens to where they hang; the edges snap.
- Side by side / Stacked arrange them at once; a click on a screen shows exact values.
- Test patterns on all outputs, to step through.
Arrangement
| Mode | What happens |
|---|---|
| Same picture on all | every output shows the whole picture in its own resolution |
| Canvas | arrange the screens freely (drag, snap, type values, side by side or stacked); each output shows its part, visuals and videos run seamlessly across all |
| Projection mapping | canvases with corner pin, grid warp and masks on the picture of each projector, see projection mapping |
Window output
Instead of full screen, an output can be a normal window with a fixed picture size (720p up to 4K, also portrait). Capture it in OBS (NDI and Syphon via OBS plugins or other tools; not built in). It also works as a projector in canvas and projection mapping.
Note
Native Syphon, Spout and NDI are planned. Until then the window output is the way to get the picture into other programs.
Test patterns
Nine test patterns to step through: color bars, grid, grid across all, numbers, grey scale, white, red, green and blue, each with the resolution, name and position of every output. Also on a key or desk channel: test pattern, next, previous.

Tip
With only one screen an output covers the interface. Esc or Close in the main window ends it.
