This must sound undecipherable to non-Mac users, sorry.

What I meant is that the resolution in dots per inch is probably set  
dynamically on the Mac, since:

- If I understood correctly, before OS X screen display was  
constructed in bitmap form, at fixed dpi resolution, but in OS X it is  
constructed vectorially, in PDF format (I think there's the same kind  
of difference between Windows XP and Vista), and then rasterized only  
at the last minute when creating screen output...

- ...based on the resolution in pixel area selected in System  
Preferences > Monitors. For example with my current MacBook 13" LCD  
monitor the resolutions available in System Preferences > Monitors are  
1280 x 800, 1152 x 720, 1024 x 768, 1024 x 640, 800 x 600, 800 x 500  
and 640 x 480, and I imagine that it is the combination of this  
setting together with the physical characteristics of the monitor (13"  
diagonal) which defines dynamically the resolution in dots per inch.

So I don't really see how the resolution defined in TeXworks via Prefs  
 > Preview fits within this picture.
