Actually the projector issue is a different one. Nobody wants to use DPI
on a projector, for the simple reason there's no projector available
with a pixel density such that you could have a decent DPI setting on
it. I'm not even sure a projector advertizes its size screen.
I'd say people would want to use a projector as if it was a virtual
screen of <insert your favourite size here>, or even simpler, as a
projection of <the current real screen>, thus using the already
configured DPI.
