+typically a game, compose a scene with overlays, then send it RMB > Fullscreen project > Some monitor.  
+This also can be used with single monitors, but its requires setting up a virtual(fake) monitor,  
+for windows required steps described [here](https://superuser.com/questions/62051/is-there-a-way-to-fake-a-dual-second-monitor)   
+[Dual monitor tools](http://dualmonitortool.sourceforge.net/) this software has these features:
