Description
Provides access to a display / screen for rendering operations.
Unity supports multi-display rendering on:
- Desktop platforms (Windows, macOS X, and Linux)
- Android (OpenGL ES and Vulkan)
- iOS
Some features in the Display class only work on some of the supported platforms. See the properties and methods for more information about platform compatibility.
Use the Display class to operate on the displays themselves, 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;
}
}
