Is there a class that can be use to get this information?
I don't think that you can get hold of this information, because
I'm pretty sure that it's not something that a connected monitor
reports to the computer.
I'm sure that there are some cases when you could have this info -
for example you could probably figure it out for machines from
Apple with built-in LCD monitors based on the model of the machine
- but in the general case I would be really surprised if you could.
So, while you can access the pixel dimensions of the monitor(s), I
don't think that you can calculate their "real world" resolution in
dpi/ppi.
Docs say that NSScreen's displayDescription method returns a
dictionary that is supposed to have an entry (key:
NSDeviceResolution) that describes the device's pixel density. You
should be able to back calculate the screen's physical dimensions
from that and the pixel dimensions.
