I'm certainly not a gui expert, but as a PyQt user, I know screen
resolution is indeed Python-accessible with PyQt. (I guess other
toolkits provide their own methods)

I've made a quick script that prints the screen X and Y resolution
(requires PyQt). Reference links to PyQt API docs are included.


In my case, it's 96 dpi, and that what I use in my matplotlibrc file for
the "figure.dpi" property. But I use a higher value (say 150) for
"savefig.dpi" so that I get better resolution when saving PNG images.

I agree with Nikolaus that the dpi value for displaying figures would be
better get by the software, if possible. Maybe a property like
figure.dpi='auto' should activate such a behavior. But this would
require many code duplicates, one for each gui toolkit.


Best,
Pierre
