Sometimes simply putting in the monitor type and/or putting in the
HorizSync and VertRefresh rates will help. Google for:

You should also be able to get those rates from the user manual. A sample:

Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "DEL"
        ModelName    "Dell 1905FP (Analog)"
        DisplaySize  380        310
        HorizSync    30.0 - 81.0
        VertRefresh  56.0 - 76.0
        Option      "dpms"

And from one of my /etc/X11/xorg.conf filesn for a Hitachi SuperScan
Elite 641 monitor:

Section "Monitor"
	Identifier	"CM641"
	HorizSync    31.0 - 75.0
	VertRefresh  50.0 - 130.0
	Option		"DPMS"
