# Display

> Provides access to a display or screen for rendering operations.

## Definition

* **Type:** Class
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public class Display
```

## Remarks

Unity supports multi-display rendering on the following platforms:

* Desktop platforms (Windows, macOS, and Linux)
* Android (OpenGL ES and Vulkan)
* iOS
* Embedded Linux
* QNX

Some features in the `Display` class only work on some of the supported platforms. For more information about platform compatibility, refer to the individual properties and methods.

Use the `Display` class to operate on the displays and [Camera.targetDisplay](/engine/6000.7/script-reference/unityengine/camera/targetdisplay.md) to set up cameras for rendering to individual displays.

Additional Resources: [Camera.targetDisplay](/engine/6000.7/script-reference/unityengine/camera/targetdisplay.md), [Canvas.targetDisplay](/engine/6000.7/script-reference/unityengine/canvas/targetdisplay.md).

## Examples

```csharp
using UnityEngine;

public class Example : MonoBehaviour
{
    Camera extCam;
    Camera cam;

    void Start()
    {
        // GUI is rendered with last camera.
        // As we want it to end up in the main screen, make sure main camera is the last one drawn.
        extCam.depth = cam.depth - 1;

        cam.SetTargetBuffers(Display.main.colorBuffer, Display.main.depthBuffer);
        extCam.enabled = false;
    }

    void Update()
    {
        if (Display.displays.Length > 1 && !extCam.enabled)
        {
            Display.displays[1].SetRenderingResolution(256, 256);
            extCam.SetTargetBuffers(Display.displays[1].colorBuffer, Display.displays[1].depthBuffer);
        }
        extCam.enabled = Display.displays.Length > 1;
    }
}
```
