Older monitors that cannot be queried for their identity will need to 
be setup in Xorg.conf in a manner similar to this:
-----------------
Section "Monitor"
        # Option "dpms"
        Identifier   "NEC MultiSync 5FG"
        VendorName   "NEC"
        ModelName    "MultiSync 5FG"
        HorizSync    27-79
        VertRefresh  55-90
        ModeLine     "1600x1200/60Hz" 162 1600 1664 1856 2160 1200 
1201 1204 1250  +HSync +VSync
EndSection
-----------------
Find somehow, the range of HorizSync frequencies your monitor can 
handle, also the range of VertRefresh and change the above figures to 
suit.  Don't guess!  Some monitors like this NEC are tough old birds, 
and can tolerate the slower horizontal frequencies quite well, but 
many of the cheaper ones might be destroyed by useing that 27 khz low 
limit, so you may want to spec a minimum of 30 there.

And that ModeLine may push some video cards to the wall so you may 
want to try a lower resolution at first.  I'd suggect trying a 
1024x768 modeline, then move up once you see a nice sharp display at 
1024x768.
