# isActive

This property tells you whether the configurator is actively configuring the external display.

## Declaration

```swift
var isActive: Bool { get }
```

## Discussion

Discussion When this property returns true, the external display is successfully configured to match the device. If it returnsfalse, the configurator is not making any configuration changes to the external display. If another AVCaptureExternalDisplayConfigurator instance takes over the configuration of the external display, this property returns false.
