# AVDisplayManager

A tvOS management object that controls whether a TV switches modes to match the video’s native mode.

```
class AVDisplayManager
```

## Overview

If you set the display manager’s [`preferredDisplayCriteria`](/documentation/AVKit/AVDisplayManager/preferredDisplayCriteria), when a user enables a Match Content setting, the TV attempts to change modes to match the currently playing video’s native display criteria.

> Important:
> Don’t directly instantiate a display manager object. Instead, access the current instance from the key window’s <doc://com.apple.documentation/documentation/UIKit/UIWindow/avDisplayManager> property.
