replace in code NSDeviceSize to NSDeviceResolution and you give "An
NSValue that contains an NSSize which indicates the device’s resolution in
dots per inch (dpi)."

width, height - screen size in pixels
Thanks very much. But, as you certainly know, the size of a pixel is
computed as
screen width in mm / screen width in pixels and screen height in mm /
screen height in pixels.
So the next question: How do I get the screen dimensions in mm (or any
other length unit) ?
Or, if this is not possible: How can I get at least some unique
identifier for an NSScreen (like "display of 12 inch G4 iBook" or:
"Apple Studio Display Model xxx") ?
Kind regards
Gerriet.
Is there a way to get the size of a pixel (or dpi) of an NSScreen?
I am NOT interested in [NSScreen deviceDescription] which - obviously
without making any real effort of getting at the truth - just returns
an arbitrary value of 72 dpi for all screens.
So: is there some function somewhere which really tells the truth
about screen resolution?
