How to extend UWP app's window into multiple screen

I'm trying to make UWP (Universal Windows Platform) application with visual C# and xaml which is displayed into multiple screen with full screen mode.

So, at first I added the code to enter into full screen mode in App.xaml.cs like below.

Windows.UI.ViewManagement.ApplicationView.GetForCurrentView().TryEnterFullScreenMode();

I'm not sure how to extend the window into multiple screen. I use two 4K displays but the application is displayed in one screen with full screen mode.

The resolution of 1 display is 3840*2160, so the application should be displayed in the size of 3840*4320 with full screen mode.

The OS presentation setting of multiple screen is "Extend".

Anybody know how to extend application window?

The application target of windows is "Windows 10 Fall Creators Update 16299"

Windows does not support natively mosaic mode.

You can connect n number of monitors, but you still only will be able to configure them with extend functionality.

Given that multiple displays requires a good and/or powerful multiple graphic cards.

Third party manufacturers like Nvidia, developed a set of drivers that can support this functionality, so, the way to go is not native to Microsoft, there is not support on the .NET framework for this.
