# isMatchingFrameRateSupported

Whether the external display supports matching frame rate to a capture device.

```
class var isMatchingFrameRateSupported: Bool { get }
```

## Discussion

If `true`, you may instantiate a configurator with a configuration specifying [`shouldMatchFrameRate`](/documentation/AVFoundation/AVCaptureExternalDisplayConfiguration/shouldMatchFrameRate) set to `true`.
