[Bug 118745] Re: Font sizes in Gutsy are vulnerable to bad X.org DPI detection

[Raptor45]

(Correct me if I'm wrong here, but... this is why to the best of my
understanding.)

The reason for knowing the DPI hasn't been too important in the past,
but could grow to become a bigger issue in the future. This is because
although most current screens are approximately 96 DPI, there is room
for improvement in the future in making denser screens for better
detail. My 20" monitor has a resolution of 1680x1050; but what if
someone has a 20" monitor that is 3360x2100? Everything would appear to
be unusably "small" on this monitor, despite them being the same size.

Using DPI properly and sizing based on actual distances, as opposed to
via pixels, means that sizes would be standardized. What is an inch on
my monitor would also be an inch on the other, just the other would look
that much more detailed. This can be important in other ways too: ever
try holding up a sheet of paper to your word document? If it doesn't
line up quite right at 100% zoom your DPI setting is probably slightly
off. As the DPI on monitors increases, this will become a bigger issue.

In your example, the graphics on both screens would be the same size.
The menu bar on each would be .25" on both, or what have you. The
problem you seem to take with proper DPI settings seems to be caused by
your viewing distance from the screen; an issue which DPI isn't meant to
correct for.
