nvidia configuration tool seems to have anything about dpi :-)

in the man xorg.conf I found this:
DisplaySize width height
 This optional entry gives the width and height, in millimetres, of the
picture area of the monitor. If given this is used to calculate the
horizontal and vertical pitch (DPI) of the screen.

do you intend this?

I found this data on my xorg:
xorg-x11-server is 7.5_1.8.0-10.3.1 by opensuse repo
xorg.conf ther isn't
xorg.conf.d there is in /etc/X11
the contents are:

the content of 50-monitor.conf is:
Section "Monitor"
  Identifier "Default Monitor"

  ## If your monitor doesn't support DDC you may override the
  ## defaults here
  #HorizSync 28-85
  #VertRefresh 50-100

  ## Add your mode lines here, use e.g the cvt tool


the content of Xorg.0.log is big, I filtered searching dpi, this seems
related to:
[    26.018] (II) NVIDIA(0): Validated modes:
[    26.018] (II) NVIDIA(0):     "nvidia-auto-select"
[    26.018] (II) NVIDIA(0): Virtual screen size determined to be 1920 x
[    26.230] (--) NVIDIA(0): DPI set to (143, 144); computed from
"UseEdidDpi" X config
[    26.230] (--) NVIDIA(0):     option
[    26.230] (==) NVIDIA(0): Enabling 32-bit ARGB GLX visuals.

if you want to see other just ask me :-)
