How do I get my dual monitors to display in the correct order so my mouse will scroll from screen to screen?
Answer:
Right-click on your desktop and select "Display Options". At the top of the resulting dialogue box, your available monitors appear as blue, numbered boxes. Each box represents a monitor.
If you want the mouse to scroll left to right across your monitors, make sure monitor "1" is on the left and monitor "2" is on the right.
To change the monitors' position, click, drag, and place the blue, numbered boxes to your preferred position. If you are unsure which monitor is "1" or "2," click the "Identify" link. The assigned monitor number will then appear on each monitor's screen.
