# wantsExtendedDynamicRangeContent

Enables extended dynamic range values onscreen.

## Declaration

```swift
var wantsExtendedDynamicRangeContent: Bool { get set }
```

## Discussion

Discussion The default value is false. If any onscreen layer has this property set to true, all rendered content is clamped to the screen’s maximumExtendedDynamicRangeColorComponentValue value rather than 1.0.
