OK, I tried it in the attached files.
Copy the "profil ka-50.lua" in your DCS/config/MonitorSetup folder.
And then open your "options.lua" in your user/saved games/dcs(whatever)/config folder and change the lines like in the attached one.
To change the settings you can use notepad++ -> https://notepad-plus-plus.org
Hope it works for you. Let me know profil ka-50.lua options.lua
