To illustrate the possibilities available with Virtual Display Manager, we will review a simple example - a two monitor configuration when each physical monitor is split into individual Virtual Displays.
Let's load one application window, which is Microsoft Word in our example:

Fig. 10. Two monitor configuration, a single Microsoft Word window is loaded as illustration.
To demonstrate the current Virtual Display configuration let's identify Virtual Displays by clicking on the "ID" button in the VDM Navigation window, accessible from the System Tray:

Fig. 11. Identifying Virtual Display IDs through "ID" button in VDM navigation screen.
At this point let's move our test window to the proximity of the desired Virtual Display, in our case Display #1:

Fig. 12. Repositioning application window to proximity of desired Virtual Display
Now, if we attempt to maximize application window it will maximize to the closest Virtual Display:

Microsoft Word Window is maximized to Virtual Display #1:

Fig. 14. Windows is maximized to the Virtual Display
Identification of Virtual Displays confirms perfect overlap of our maximized window and Display #1. Note that window state is a "true" maximized state and cannot be moved from its location unless the state is change to normal.

Fig. 15. Identifying Virtual Displays. One maximized window is shown.
We can go further and add more windows maximizing them to separate Virtual Displays as illustrated in the next picture:

Fig. 16. Each Virtual Display has a window in maximized state.
In case the particular window should be maximized to the physical display, "Monitor" menu within VDM Navigation window can be used. Below a window from Microsoft Word is maximized to the first physical monitor which hosts 2 Virtual Displays (Display #1 and #2):
