Hello J.Silva,
if you manually make changes to settings the phone will upload a <mac>-phone.cfg file which will contain the changed settings.
In addition the Admin Guide should contain this information.
Also the following post => here<= shows the up.numOfDisplayColumns parameter.
I also just added a transparent FAQ post:
