Well, for a desktop system, the monitor (except really old monitors)
will report screen dimensions, and since X knows the resolution that's
being used, it can calculate the true number of dots per inch, allowing
it to better select appropriate font sizes for display on the desktop
system.
Myth's frontend requires 100 DPI to align graphics and text
appropriately with the theming system. So, on a system that only runs
Myth, setting 100DPI is definitely the right thing. Setting it on a
system that runs Myth and other apps (i.e. is a part-time Myth frontend
and usually a desktop system) is a question of compromises. The user
must choose which is more important.
On my 19" monitor running at 1280x1024, I have 87x92 dots per inch, so
using 100DPI wouldn't necessarily make a very noticeable difference. On
my 15.4" laptop widescreen running at 1920x1200, I have something like
37 dots per inch--which would look very bad at 100DPI.
Note, however, that with TwinView/MergedFB/etc, you have another issue
because an X server uses a single DPI for all screens. Therefore, it
may actually be appropriate to specify a DPI in your case, but I would
do it in the X config file (not a command-line option). IMHO, it's
/wrong/ for any distro to explicitly define the "-dpi" option for
starting X, as it overrides any setting you put in your X configuration
file. (Basically, it seems to be the MS approach of protecting the user
from him/herself.)
