Use the Screen object.

Getting the monitor count

ShowMessage(IntToStr(Screen.MonitorCount))

Getting monitor details

Screen.Monitors[i].Left (integer)
                  .Top (integer)
                  .Width (integer)
                  .Height (integer)
                  .BoundsRect (TRect)
                  .WorkareaRect (TRect)
                  .Primary (boolean)

where i is the index of the monitor, that is, i = 0, 1, ..., Screen.MonitorCount - 1.

So, for instance, to make the form occupy the entire ith monitor, use

BoundsRect := Screen.Monitors[i].BoundsRect; // or you could make the rect smaller
WindowState := wsMaximized; // possibly
