screen #0:
  dimensions:    1680x1050 pixels (431x272 millimeters)
  resolution:    99x98 dots per inch

In xorg.conf:

Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "Belinea"
        ModelName    "10 20 35W"
        DisplaySize  434        272 

(only because the dcc-autoprovided size is not as precise as I'd like it
to be)
