# SCDisplay

An instance that represents a display device.

```
class SCDisplay
```

## Overview

A display object represents a physical display connected to a Mac. Query the display to retrieve its unique identifier and onscreen coordinates.

Retrieve the available displays from an instance of [`SCShareableContent`](/documentation/ScreenCaptureKit/SCShareableContent). Select a display to capture and use it to create an instance of [`SCContentFilter`](/documentation/ScreenCaptureKit/SCContentFilter). Apply the filter to an instance of [`SCStream`](/documentation/ScreenCaptureKit/SCStream) to limit its output to content matching your criteria.
