Not set in X resources:
$ xrdb -query | grep -c dpi
0

I didn't even know what X settings was. A quick search found 
https://www.freedesktop.org/wiki/Specifications/XSettingsRegistry/, which led 
me to the "xsettingsd" package. But it's not set there either:

$ dump_xsettings | grep -ci dpi
0

Anyway, you're right that physical monitor sizes are known to be wildly 
broken. Therefore, relying on what XRandR reports is risky. I'll set up 
~/.Xresources.
