nView display modes enable you to view your desktop in one of several multi-display modes to make the best use of the displays (monitors) that are connected to your computer.
In Single mode, your desktop is displayed on a single monitor
In Clone mode, your desktop is duplicated on each display.
In Horizontal Span and Vertical Span modes, the desktop is stretched across the displays.
NOTE: Horizontal and Vertical Span modes are available only under Windows XP.
In Dualview mode, you have extra desktop space on the additional display, which you can configure independently. You can move your desktop items and distribute applications to this additional display.
Note: Before you select an nView display mode to work with, from the Select the display pair combination . . . list in step 2 you have to select the two displays corresponding to the physical position of your displays.
