Multi-Windows on one large Display. Four 1920x1080 to one 3840x2160

In Vision, you can get four "full-screen" windows in the four quadrants like this:

Run 4 Ignition Desktops on 4k Diplay

That’s right; you’ll want to strip the title bar and window borders from your original window too. You’ll probably need something closer to the first code I posted above for that, referencing the window you open in your client startup script: from javax.swing import JFrame hostNames = ["HostNameThisAppliesTo","AnotherHostNameThisAppliesTo"] if system.net.getHostName() in hostNames: # Setup initial desktop. desktop = system.nav.openWindow("PathToWindow") while not isinstance(desktop, JFrame)…

You could code different options for the different display configurations (detect display config and then choose desired option). If desired, you can give users buttons/menu to make the appropriate arrangement (you can switch windows back and forth between "full-screen" and windowed mode at run-time with similar code).

Also note an alternative suggestion from @Sanderd17 at the bottom of the linked thread:

Run 4 Ignition Desktops on 4k Diplay

I know the solution is already given. But we’ve also had a case where we had to support 4K screens, and they expected more content on the 4K screen than on the regular screens. Our solution was to simply develop each screen as a template. For the small screens, use those templates directly into a window. And for the big screen, show 4 of those templates. Even if the application is already developed, it’s usually not that hard to copy-paste all content from a window to a template.
