Not sure what you are meaning here. If you run xrandr commands "manually"
at every restart, then you shoud use a login script to do this.

I have to use xrandr to adjust video output from my audio-video Linux box
to a old LCD TV: I have a small login script to have xrandr setting up
things at every login...

Incidentally, I would like to share this two useful links:
- modeline generator:
http://xtiming.sourceforge.net/cgi-bin/xtiming.pl
- modeline database

Premise: I have never used more than 1 monitor... And excuse me if this is
of no interest for you.

But, searching in the net (for "linux 4-monitor" or "linux multi-monitor"),
it seems X can handle up to 16 monitors since years, either Nvidia or
AMD, either proprietary or free drivers...

Maybe you could be interested in a possible hardware solution, as pheraphs
could be a multi-monitor appliance (which surely is not cheap)...
Something like the Matrox QuadHead2Go Series:
