Frequency ranges themselves didn't help but I solved the problem already
by specifying Modeline which was generated by cvt(1). Thanks anyway.

Now my Monitor section in xorg.conf looks like this

   Section "Monitor"
        Identifier   "Monitor0"
        Modeline "1920x1080"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 
-hsync +vsync
        VendorName   "Dell"
        ModelName    "Dell U2312HM"
        HorizSync    30 - 83
        VertRefresh  56 - 76
        Option      "DPMS"
   EndSection

Do you have any idea why DDC may fail? I tried Linux live-cd and it
worked just fine.
