## Fields & Properties

### HologramCamera Camera

The `HologramCamera` instance used when a second display is connected. The camera is deactivated until a second display is detected.

Width of the 2D screen resolution on the mobile device. Default value is 600 pixels — if set to 0, it will use the device's native resolution width.

### int Height2D

Height of the 2D screen resolution on the mobile device. Default value is 1000 pixels — if set to 0, it will use the device's native resolution height.

### string LoadedVisualJsonPath

Path to the calibration JSON file. Setting this property triggers a display refresh.

### static string VisualJsonFilePath

Static property that provides the path to the persistent calibration JSON file.

### UnityAction onCalibrationLoaded
