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; } }
| activeEditorGameViewTarget | Get the Editors active GameView display target. |
| displays | The list of connected displays. |
| main | Main Display. |
| active | Gets the state of the display and returns true if the display is active and false if otherwise. |
| colorBuffer | Color RenderBuffer. |
| depthBuffer | Depth RenderBuffer. |
| renderingHeight | Vertical resolution that the display is rendering at. |
| renderingWidth | Horizontal resolution that the display is rendering at in the viewport. |
| requiresBlitToBackbuffer | True when the back buffer requires an intermediate texture to render. |
| requiresSrgbBlitToBackbuffer | True when doing a blit to the back buffer requires manual color space conversion. |
| systemHeight | Vertical native display resolution. |
| systemWidth | Horizontal native display resolution. |
| Activate | Activates an external display. For example, a secondary monitor connected to the system. |
| SetParams | Windows platforms only. Sets rendering size and position on screen. |
| SetRenderingResolution | Sets rendering resolution for the display. |
