Have a look at this API documentation page...
Can anyone explain to me the difference between the rcMonitor and rcWork components of the MONITORINFO structure? Although I'm happy with the idea that a window has areas you can't work with (like the caption for instance), I don't really see how this applies to monitors...
All contributions gratefully received...

rcMonitor is the total resolution of the display
rcWork is the max area you can use,eg if you went fullscreen maximized a window
The work area is the portion of the screen not obscured by the system taskbar or by application desktop toolbars.
