With my samsung LCD monitor it refused to use the specified VertRefresh
(and thus refused to enable maximum resolution) until I added another
option in the xorg.conf file
Mine has three lines that made it work properly, but only when all are
present in the "Monitor" section. You may need to put these in the
sections for both monitors.
VertRefresh 60.0 - 60.0
Option "IgnoreEDID"
DisplaySize 430 320
I needed the first to limit the value to the monitor default.
The second is an option from the nVidia documentation to make X ignore
the EDID data from the monitor. X by default overrides the specified
values for horizontal and vertical refresh and uses the reported EDID
values.
The third was needed to set the DPI since the EDID values are ignored
and it has to have some way to compute the dpi. Obviously the display
size values may be different for your monitor. Mine is a SyncMaster
