If I understand you correctly you are saying that using -dpi 75 informs
an application which wants to display a 72 point font that it will be
allowed 75 pixels whereas with -dpi 100 it will get 100 pixels. Having
spent some time in the recent past playing with this setting I have to
wonder why it is then that changing it on my system does not alter the
font size on the screen at all with the majority of applications I use.
There may be others, but only I have found only Lyx, August and Ted to
respond to an alteration in the dpi switch.
This may not be correct, but the only explanation I can think of to
account for this behaviour is that most applications do not use the dpi
value sent to the X server.
