I had to change the section below to set the VertRefresh so it forced
the server to use 60.0 and it worked for me. The commented line was what
was detected, but the monitor (flat panel) would not display the max
resolution until I fixed the refresh rate.
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Samsung SyncMaster 213T"
HorizSync 30.0 - 81.0
# VertRefresh 56.0 - 75.0
VertRefresh 60.0 - 60.0
Option "dpms"
EndSection
