I bet you are not getting the refresh rates right. Most LCDs work best
at a few (unusual low) refresh rates.

You also may try using the newer XFree 4.1 or 4.2, since that supports 
querying the monitor for it's capabilities.

I use this on my (different) LCD:

ection "Monitor"
        Identifier   "Monitor0"
        VendorName   "MEL"
        ModelName    "LSA820W"
        HorizSync    31.0 - 80.0
        VertRefresh  30.0 - 85.0
EndSection

And actualy I'm not sure if reducing the upper VertRefresh rate to 75 wouldn't
improve the display quality.
