ini file on PM Glass cockpit

Some options in the PFD/ND ini. file do not apply obviously to the Engine Display ini.file.
eg: radar sweep=on.
Is it better to have both ini. as similar as possible to avoid potential conflicts or it does not matter at all.
I'm making a clean reinstall..hence my stupid questions!!
Cheers

Hallo Jack,

In my system the PFD/ND is on one PC, the upper EICAS on another PC and the lower EICAS on a third. The INI files are all very much different.
