A test app for the upcoming resolution-independent world


ShowAllResolutions puts a window on each screen with two pieces of information:

“Resolution from Quartz Display Services: 98.52×96.33 dpi. Resolution from NSScreen: 72 dpi.”

The former information may satisfy your curiosity, if you ever wondered what the real resolution of your monitor is. The latter information will be useful for programmers who use the upcoming resolution-independent Mac OS X.

ShowAllResolutions requires Mac OS X 10.4 or later. It will not work on earlier versions of Mac OS X. (It could be made to work on 10.3.9, if somebody is interested enough to submit a patch.)
