Often the configuration utility cannot determine the exact DisplaySize... so
its approximate... like 310x230. This measurement is the actual viewing size
in mm. (You can measure it with a millimeter ruler if you like). The dots per
inch is a conversion on the physical resolution of the monitor. Doing the
math on your pixels vs dots per inch you have a 15" monitor. Probably the
313x232 is correct... and you just need to specify that setting in xorg.conf.
But I would measure the actual display area with a mm scale first. Of course
you can use SaX to set the value or you can edit xorg.conf yourself with vi.

Kind regards,
