Streetdeck does not have Multi Monitor ability. Drive soft is just spliting up signal from the vga output. Its one ugly interface but i really dont know how the software works. all the touchscreen goes to one usb interface. No touchscreen interface can control different thing. Touchscreen is like a mouse one pointing device per system. You will take focus on one screen when you click on the other screen. Example: you are controling your touchscreen from the front and you kids are in the back playing a game. they will have full control until you click on the screen to change music of something. then they have to take focus back to what they are doing. Basically only one program or screen can have focus at one time. Not one mouse or pointing device doing different thing.
