Description
Returns the display having the nearest top-left corner from the specified Point point.
DisplayFromPoint returns the display whose work area's top-left corner is the nearest (in the virtual screen coordinates) from the specified Point point.
The distance is calculated as the sum of absolute values of offsets between the Top and Left coordinates of a WorkArea and the correspondent X or Y coordinates of the specified Point point. That is like:
Abs(WorkArea.Top-Point.Y) + Abs(WorkArea.Left-Point.X)
The virtual screen is the bounding rectangle of all displays used to comprise the desktop.
