in other words, if you set dpi accordingly in your X server's settings, 
it should work.
something like this:

#!/bin/bash

XFT_SETTINGS="
Xft.antialias:  1
Xft.autohint:   0
Xft.dpi:        96 <== you need a different value here.
Xft.hinting:    1
Xft.hintstyle:  hintfull
Xft.lcdfilter:  lcddefault
Xft.rgba:       rgb
"

echo "$XFT_SETTINGS" | xrdb -merge > /dev/null 2>&1

save it, make executable and add to your autostart.
