# extendedDynamicRangeOutput

Specify whether the target Metal layer has been configured for EDR output.

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

## Discussion

If the Metal layer that this [`RealityRenderer`](/documentation/RealityKit/RealityRenderer) will be rendering into has been configured
to output extended dynamic range content (i.e. the property
`QuartzCore/CAMetalLayer/wantsExtendedDynamicRangeContent` on the target
`QuartzCore/CAMetalLayer` has been set to `true` and a pixel format that supports EDR
content has been set), this property should be set to `true` so that [`RealityRenderer`](/documentation/RealityKit/RealityRenderer)
adjusts its tone mapping accordingly.

To control the amount of headroom available for extended dynamic range content, see
[`extendedDynamicRangeHeadroom`](/documentation/RealityKit/RealityRenderer/extendedDynamicRangeHeadroom).

The default value is `false`.
