[Solved] Intel video driver - wrong DPI

I can't resolve this problem.
I have a Dell Inspiron 640m laptop with Intel 945GM videocard.

00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)

Version of video driver:

xf86-video-intel 2.1.1-2

Now I have 120x120 DPI:

# xdpyinfo | grep resolution
  resolution:    120x120 dots per inch

But I want to get 96x96.

Parts of my xorg.conf:

Section "Device"
        Identifier  "Card0"
        Driver      "intel"
        VendorName  "Intel Corporation"
        BoardName   "Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller"
        BusID       "PCI:0:2:0"
EndSection

Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "AUO"
        ModelName    "1247"
EndSection

I tried to give DisplaySize parameter, but intel driver ignores it. I tried "Option "DPI" "96x96"", but also no effect.
What can I do to fix it?
Thanks for any help!

Hi broom,
try to add in section "Monitor" this:

Hi broom,

It helped. No DDC + DisplaySize gave the correct DPI.
I am so confused, that the solution was so simple... Thank you very much!
