Output

Last updated 7 August 2026

Getting the scene to real hardware: every projector and display reaches a physical output, and audio reaches a device.

Skip this stage when preparing a project away from the installation — a scene builds and content plays without any of it. Do it on site.

Do this in order

  1. Route video — connect each projector and display to the GPU output it is cabled to. Until this is done the scene can look perfectly correct while the screen stays black.

  2. Route audio — create an audio output for the device and channels you are using, then connect what should reach it.

  3. Add a matrix mixer — only when the channel counts going in and coming out differ, or individual channels need adjusting on the way.

Done when: every projector and display in the scene shows a signal on its physical device, and audio reaches its outputs. Nothing here is about what the image looks like — that is the next stage.
