# wantsExtendedDynamicRangeContent

Enables extended dynamic range values onscreen.

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

## Discussion

The default value is <doc://com.apple.documentation/documentation/Swift/false>. If any onscreen layer has this property set to <doc://com.apple.documentation/documentation/Swift/true>, all rendered content is clamped to the screen’s <doc://com.apple.documentation/documentation/AppKit/NSScreen/maximumExtendedDynamicRangeColorComponentValue> value rather than `1.0`.
