# CGCompleteDisplayConfiguration(_:_:)

Completes a set of display configuration changes.

## Declaration

```swift
func CGCompleteDisplayConfiguration(_ config: CGDisplayConfigRef?, _ option: CGConfigureOption) -> CGError
```

## Parameters

- `config`: The display configuration that contains the desired changes. On return, this configuration is no longer valid.
- `option`: The scope of the display configuration changes. Pass one of the constants listed in doc://com.apple.coregraphics/documentation/CoreGraphics/CGConfigureOption.

## Return Value

Return Value A result code. If the request to apply changes is successful, the result is kCGErrorSuccess. For other possible values, see CGError.

## Discussion

Discussion This function applies a set of display configuration changes as a single atomic transaction. The duration or scope of the changes depends on the value of the option parameter. For more information about possible scopes, see CGConfigureOption. A configuration change can fail if you request an unsupported display mode or if another application is running in full-screen mode.
