# VZGraphicsDisplay

A class that represents a graphics display in a VM.

```
class VZGraphicsDisplay
```

## Overview

Don’t instantiate a `VZGraphicsDisplay` directly. Graphics displays are first configured on a [`VZGraphicsDeviceConfiguration`](/documentation/Virtualization/VZGraphicsDeviceConfiguration) subclass. When you create a [`VZVirtualMachine`](/documentation/Virtualization/VZVirtualMachine) from the configuration, the displays are available through the [`displays`](/documentation/Virtualization/VZGraphicsDevice/displays) property of the configuration’s [`VZGraphicsDevice`](/documentation/Virtualization/VZGraphicsDevice).

## Topics

### Getting the display size

[`sizeInPixels`](/documentation/Virtualization/VZGraphicsDisplay/sizeInPixels)

Returns the size of the display, in pixels.

### Observing changes to the display configuration

[`addObserver(_:)`](/documentation/Virtualization/VZGraphicsDisplay/addObserver(_:))

Adds an observer to notify about display configuration changes.

[`removeObserver(_:)`](/documentation/Virtualization/VZGraphicsDisplay/removeObserver(_:))

Removes a display configuration change observer.

[`VZGraphicsDisplayObserver`](/documentation/Virtualization/VZGraphicsDisplayObserver)

A protocol you implement to observe state changes in graphic displays.

### Changing the display configuration

[`reconfigure(sizeInPixels:)`](/documentation/Virtualization/VZGraphicsDisplay/reconfigure(sizeInPixels:))

Resize this display with the new dimensions you provide.

[`reconfigure(configuration:)`](/documentation/Virtualization/VZGraphicsDisplay/reconfigure(configuration:))

Reconfigure this display with the new display configuration you provide.
