Window 8 with dual monitors

[subover]

How to change the full screen application between dual monitor desktop in windows 8.1? Nowadays, I have a game that running in full screen in a desktop with windows 8.1. That desktop has two monitors. However, when I try to change the application to the second monitor, the application does not change its screen. I have already tried the shortcuts: win + shift and <- or ->, but none have worked.
Any suggestions?

Try pressing Alt + Enter when in game (I assume you play in full screen) and trying dragging the window over to your second screen.

Right click on your desktop and select "Screen Resolution"
Select the monitor you want as your main display and click the magic button

Your applications will now run on that monitor.
