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.
