LibGDX Multiple Fullscreen Windows

Question

I am writing a program to display text on two monitors.

Right now my method is to launch a LibGDX window on both monitors, then control each separately. However, when both are in fullscreen, only one window can have focus. The out-of-focus window gets hidden. How do I solve this?

Specs:

• Windows 10

• Java 1.8

• LibGDX 1.9.3, using LWJGL 3 backend

Code:

• In the ApplicationListener:

  @Override
  public void show() throws RuntimeException {
     // Throws exception if it is set to go to monitor 1 and it does not exist
  
     if (external && Gdx.graphics.getMonitors().length < 2)
          throw new RuntimeException("Cannot extend to secondary monitor.");
  
      Gdx.graphics.setFullscreenMode(Gdx.graphics.getDisplayMode(Gdx.graphics.getMonitors()[external ? 1 : 0]));
  }
  

• Then, to open the window:

  @Override
  public void openWindow(ApplicationListener a) {
     Lwjgl3WindowConfiguration config = new Lwjgl3WindowConfiguration();
  
     config.setTitle(title);
  
     config.setWindowListener(new Lwjgl3WindowListener() {
  
         @Override
         public void iconified() {}
  
         @Override
         public void focusLost() {}
  
         @Override
         public void focusGained() {}
  
         @Override
         public void filesDropped(String[] files) {}
  
         @Override
         public void deiconified() {}
  
         @Override
         public boolean closeRequested() { 
             return true;
         }
     });
  
     Lwjgl3Application app = (Lwjgl3Application) Gdx.app;
     window = app.newWindow(a, config);
     DesktopLauncher.openWindows.add(window);  // Used to close all windows later
  }
  

Am I looking at this the wrong way? Thanks!
