Arranging the Displays in Extended Mode

In Extended Desktop Mode, you may need to arrange the Desktops to match the physical layout of the displays so that the mouse moves correctly across all displays. 

To arrange the Desktops:

1. In Display Settings, the numbers representing the displays indicate the current Desktop arrangement.  If the logical arrangement does not match the physical placement of the displays, the mouse will not move across the displays in the correct order.

2. Click Identify to see how the displays are being detected by Windows.  A unique number will appear on the lower left corner of each display.

In this example, Windows Display Settings does not match the physical arrangement of the displays

3. In Display Settings, drag and drop the boxes so that they match the order of the physical displays as shown above.  In this example:
   
   From:

To:

Now the logical display arrangement matches the physical placement of the displays
