Multiple monitors overview
On many portable computers and some desktop computers (those with two video
ports on one video card), you can expand your display to a second monitor by using
Dualview. Dualview is very similar to the multiple monitor feature,
with the exception that you cannot select the primary display. On a portable
computer, the primary monitor is always the LCD display screen. On a desktop
computer, it is the monitor attached to the first video out port.
Once you attach the second monitor and turn on your computer, use Display in Control
Panel to configure your settings, just as you do with multiple monitors.
Dualview can be used with docked or undocked portable computers.
Arrange multiple monitors
This procedure applies when two or more monitors are connected to one
- Open Display in Control Panel.
- On the Settings tab, click Identify to display a large number
on each of your monitors, showing which monitor corresponds with each icon.
- Click the monitor icons and drag them to positions that represent how
you want to move items from one monitor to another, and then click OK or
Apply to view changes.
- To open Display, click Start, click Control Panel, and
then double-click Display.
- The icon positions determine how you move items from one monitor to another. For
example, if you are using two monitors and you want to move items from one monitor to the other by
dragging left and right, place the icons side by side. To move items between
monitors by dragging up and down, place the icons one above the other. The icon
positions do not have to correspond to the physical positions of the monitors.
You can place the icons one above the other even though your monitors are side
