Monitor setup help !

MS Flightsim X
I have 2-3monitors with split screen function on the Graphics card.
I Want one screen to be the cockpit view.
(without any instruments etc)
The other 1 o 2 screens I want instruments, GPS etc.

Fixing this is no problem BUT, how do I save those settings ?
I have to do all this work every time a start the sim.
I’m not a computer pro so please don’t ask me to configure some strange xxx.cnf file…

Is there any easy way, or maybe even a separate program to use ?
