Windows gives you a choice of 96 dpi, 120 dpi or (in later versions) a
"custom" setting. The default is 96 dpi; some applications will mess
up if you use a different setting (due to selecting font sizes in
points but specifying most positions and sizes in pixels).

That's because most of the supplied bitmap fonts are designed for 75
dpi (i.e. you get the usual 8/10/12/14/18/24 point sizes on a 75 dpi
display), although some of the fonts are also available at 100dpi.

If you choose any other resolution, you will need to use outline fonts
exclusively; anything which specifies font sizes in points will
produce very ugly results if it has to use rescaled bitmap fonts.
