# CGDisplayAvailableModes(_:)

Returns information about the currently available display modes.

## Declaration

```swift
func CGDisplayAvailableModes(_ dsp: CGDirectDisplayID) -> CFArray?
```

## Parameters

- `dsp`: The identifier of the display to be accessed.

## Return Value

Return Value An array of dictionaries with display mode information, or NULL if the display is invalid. The array is owned by the system and you should not release it. Each dictionary in the array contains information about a mode that the display supports. For a list of the properties in a display mode dictionary, see Display Mode Standard Properties and Display Mode Optional Properties. For general information about using dictionaries, see CFDictionary.

## Discussion

Discussion This deprecated function returns an array of display mode dictionary. Starting in OS X v10.6, display mode dictionaries have been replaced by the CGDisplayMode opaque type. Whereas display mode dictionaries returned by CGDisplayAvailableModes are owned by the system and are not to be released, display mode opaque type references returned by CGDisplayCopyAllDisplayModes are owned by the caller and you must release them.
