Description

Provides access to a display or screen for rendering operations.

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 to set up cameras for rendering to individual displays.

Additional resources: Camera.targetDisplay, Canvas.targetDisplay.

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;
    }
}
