I'm quite confused by the nomenclature; what does DPI really mean?
The way I interpret it, it says how many pixels there are per inch of the display. Now naturally, you can't change this (not on LCDs, anyway). But operating systems have a setting to "change" the DPI... but what does that mean?
If I "change" my DPI from 96 to 110, shouldn't that make everything smaller, because I'm supposedly fitting more pixels to every inch on the display (by definition)? Why does everything get bigger instead?
