Appararently difference DPI / Text Scaling in multiple X Screens

Yello,

having a bit of an issue over here in a 4 X screen (2 nVidia card) setup.

I've got it all working and openbox up and running on it and all that jazz, but text and everything else on my left and right monitors is a difference size that on the middle monitor (the fouth is an HDTV that just gets movies and sports played on in, so I don't really care about the text size).

All three monitors are 22" 1680x1050 monitors, using the same modeline in my Xorg files.

The issue is shown on the following (stiched together) screenshot:

My Xorg.conf.d/20-Nvidia.conf:

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 331.20  (buildmeister@swio-display-x86-rhel47-05)  Wed Oct 30 18:20:32 PDT 2013

Anyone got any ideas why this is going on and how to fix it?

Last little thing I have to do before my setup is done.
