Multi-Display Windowed Mode

Hello unity forumers,
I have a fully functioning multi-display system. When ever it is running, it auto-maximizes the screens on both displays. This causes one major issue because it removes the frame around the player (the frame with the minimize, maximize, and exit button in the top right corner). I need to be able to get that frame back around the main player window and am not sure how to make that possible. If anyone one has a solution or suggestions please share. Thank you!



Regards,
BD

 

@karl_jones any thoughts on this since you are familiar with my previous posts. i.e. http://forum.unity3d.com/threads/how-to-multi-display-resizing-display-2.398376/

 

Sent a PM with all the code from my display system. If anyone else is interested, then I will share snip-its here.

 

@karl_jones , An alternative to windowed mode in MD would be to do a reset on the display system so that way display 2 is deactivated again. When I leave the scenarios that require MD I return to the start screen. Is there a way to call a reset on the unity system? What we are trying to avoid is the user having to quit the player in order to have function single display lessons after having completed a MD lesson.

Hopefully: Display.displays[1].DeActivate(); is added and supported in the future.

 

Go @karl_jones ! @BisuDagger gets super excited when you provide help to him and he's KIND OF AN ogre.... so thank you for making him happy and helping him

Any news on this? I'm looking for the same result as BisuDagger; being able to run windowed on the primary monitor while having one or multiple external monitors in full screen.

 

@karl_jones thank you for keeping up with this thread. Is there anyway way we can get access to deactivating multidisplay? Returning the screen to single display mode is a necessity for me. Even seeing the hidden code that activates multidisplay would be a huge help. This is putting a halt on a major project of mine and it actually has recently prevented a product from being shipped.

 

I actually had a big win this morning after posting here. https://www.assetstore.unity3d.com/en/#!/content/30563
This unity store asset has a call "Window.Border()" that resets the sim and returns the boarder to the window. It fits perfectly with my case scenario where the user will leave a lesson and return to the start screen anyway. This is a super useful plugin for anyone needing it in the future.

 

Hi,
same problem here. Is there any solutions currently?

 

ANY UPDATES TILL NOW we havent got deactivate system .added

 

Hi,

ok, as i understood its not possible to have one screen on "window mode" and the other screen on "fullscreen mode". But is it possible to have both on windowed mode or means several displays always full screen mode?

Thanks for the info!

Cheers, Marc

 

Hey karl_jones,

actually i found a solution to get multiple displays in "windowed" mode. It works even with one fullscreen and one windowed display. At the end I needed two displays in window mode so i set up three displays on my Computer. In my Unity scene i set up 2 Cameras and subscribed them to display 2 and 3. One of my 3 displays is empty. With this i get two displays in windowed mode.

In a script on a gameobject is just said:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using System;
4. using UnityEngine.UI;
5.  
6. public class DisplayScript : MonoBehaviour
7. {
8.     int width = 1730;
9.     int height = 570;
10.     int xpos = 130;
11.     int ypos = 240;
12.  
13.     int width2 = 1920;
14.     int height2 = 1000;
15.     int xpos2 = 0;
16.     int ypos2 = 0;
17.  
18.     void Awake()
19.     {
20.         if (Display.displays.Length > 1)
21.         {
22.             Screen.fullScreen = false;
23.             Display.displays[1].SetParams(width2, height2, xpos2, ypos2);
24.             Display.displays[1].Activate(width2, height2, 60);
25.  
26.         }
27.         if (Display.displays.Length > 2)
28.         {
29.             Screen.fullScreen = false;
30.             Display.displays[2].SetParams(width, height, xpos, ypos);
31.             Display.displays[2].Activate(width, height, 60);
32.  
33.  
34.         }
35.     }
36. }

I am on Unity 2018.2.6f1

 

Hi,

Is it possible to have display[0] windowed and all other displays at fullScreen?

 

Hey,

i am not sure, but you can test the code above setting the display[0] to "Screen.fullscreen = true".

Good luck.

 

Hi, any news on this ? It's been 4 years now and still no md improvements?

 

Im having the same issue here. Any news about md since 2016?

 

i am also looking to get this working. I need screen 1 to be windowed but screen 2 to be full screen

 

Any solution?

 

Any progress on this? I want to run one screen windowed, the other fullscreen.

 

Any news about window mode can be used in the Multi-Display? @karl_jones thanks

 

Has anyone managed to make the X and Y coordinates of the windowed displays work?? It doesn't work here on either 2021.3.25f1 or 2022.3.17f1.
I have a simple scene in a URP project with 3 cameras assigned to Displays 1/2/3. I run this on my laptop connected to a total of 3 displays and the width/height are respected, but not XY coordinates.

My script is here:

Code (CSharp):

1. using UnityEngine;
2.  
3. public class DisplayScript : MonoBehaviour
4. {
5.     int width = 800;
6.     int height = 600;
7.     int xpos = 10; // X and Y don't work!
8.     int ypos = 20; // X and Y don't work!
9.  
10.     int width2 = 640;
11.     int height2 = 480;
12.     int xpos2 = 30; // X and Y don't work!
13.     int ypos2 = 40; // X and Y don't work!
14.  
15.     void Awake()
16.     {
17.         if (Display.displays.Length > 1)
18.         {
19.             Screen.fullScreen = false;
20.             Display.displays[1].SetParams(width2, height2, xpos2, ypos2);
21.             Display.displays[1].Activate(width2, height2, 60);
22.  
23.         }
24.         if (Display.displays.Length > 2)
25.         {
26.             Screen.fullScreen = false;
27.             Display.displays[2].SetParams(width, height, xpos, ypos);
28.             Display.displays[2].Activate(width, height, 60);
29.         }
30.     }
31. }
32.  

In 2022.3.17f1 the API has changed a bit but the results are the same, it still doesn't work:

Code (CSharp):

1. using UnityEngine;
2.  
3. public class DisplayScript : MonoBehaviour
4. {
5.     int width = 800;
6.     int height = 600;
7.     int xpos = 10; // X and Y don't work!
8.     int ypos = 20; // X and Y don't work!
9.  
10.     int width2 = 640;
11.     int height2 = 480;
12.     int xpos2 = 30; // X and Y don't work!
13.     int ypos2 = 40; // X and Y don't work!
14.  
15.     void Awake()
16.     {
17.         RefreshRate r = new RefreshRate();
18.         r.numerator = 60;
19.         r.denominator = 1;
20.  
21.         if (Display.displays.Length > 1)
22.         {
23.             Screen.fullScreen = false;
24.             Display.displays[1].SetParams(width2, height2, xpos2, ypos2);
25.             Display.displays[1].Activate(width2, height2, r);
26.  
27.         }
28.         if (Display.displays.Length > 2)
29.         {
30.             Screen.fullScreen = false;
31.             Display.displays[2].SetParams(width, height, xpos, ypos);
32.             Display.displays[2].Activate(width, height, r);
33.         }
34.     }
35. }
36.

Any updates? Just being able to deactivate, resize and move the secondary windows would be great.
