Test Functions
Diagnostics → Test Functions
Test Functions send one-shot commands to a connected display so you can verify installation without building a temporary screen layout.
Camera
| Action | What it does |
|---|---|
| Show Camera Full Screen | Shows the camera overlay full screen on the display |
| Hide Full Screen Camera | Hides the full-screen camera overlay |
| Select Camera Input 1–4 | Switches the active camera input |
Use these after wiring cameras to confirm the correct input and that full-screen preview works on the device.
Audio
Audio test actions appear in the list for future installation checks. Some may be disabled until the audio feature is available on your firmware.
Requirements
- The display must be connected to Display Studio.
- Configuration write is not required for these one-shot tests; they drive live device behaviour.
