Python : Display Manager

Explanation
We have 3 monitors on each PC. Each screen displays 1 software.
Monitor 1 - iexplorer.exe
Monitor 2 - chrome.exe
Monitor 3 - Pos.exe

We have programmed a small utility that changes the display of the screens.

Button 1 (start)
Monitor 1 - msedge.exe (fullscreen)
Monitor 2 - chrome.exe (fullscreen)
Monitor 3 - Pos.exe (fullscreen)

Button 2
Close msedge.exe
Show Monitor 2 on 3

Button 3
Remove setting of Button 2
Monitor 1 - msedge.exe (fullscreen)
Monitor 2 - chrome.exe (fullscreen)
Monitor 3 - Pos.exe (fullscreen)

Problem:
Each PC uses different monitor numbers ex: \DISPLAY5, \DISPLAY1, \DISPLAY2.

Request:
To be able to use a configuration.ini file to write in the code which are the monitors of the PC.

Ex:
[Configuration]
frontview = \DISPLAY5
topview = \DISPLAY2
mainview = \DISPLAY1

See code for more information on what we want to do.
