2.Check the ID numbers of your monitors by clicking the Identify button.

A large number appears in the center of each monitor’s screen; it corresponds to the number of the icon in the control panel. The ID numbers help you identify which icon represents which monitor.

3.Decide which monitor is your main monitor and drag the menu bar to the top of that monitor icon.

You may want to make the largest one the main monitor because some programs limit their window size to the size of the main monitor, or you may want to make your color monitor the main monitor.

4.Drag the icons to approximate the positions of your monitors.

The pointer can move from one screen to another where the monitors’ icons touch in the control panel.

5.Choose Restart from the Special menu.
