Win7 How do I set up a dual monitor?

in general, our computer is a computer with only one display, but because of the need for work, will use two, or even more than three monitors. Using the Win7 system user, you want to set up a computer with two monitors. How do I set it? Set up a dual monitor what is the method? Let's talk about the Win7 system to set up a dual-monitor method.

The steps are as follows:

One or three different settings:

"Extended display":

When you connect two monitors to your computer, the feature "extended display" is by default. The extended display is to expand the display to two monitors, such as my machine is a 1440x900 resolution and a 1280x1024 resolution of the machine, extended display after the total resolution is 1440x900+1280x1024.

Second, "Copy display":

If you use the "Copy display" method, both displays are displayed using a display resolution that you can use. For example, two monitors on my machine now support the display of 1280x800, and two monitors display exactly the same content.

The effect is as shown in the figure:

Third, "Single Display display":

If you use the "Display desktop with only 1th monitor", the other monitor will not work. You are free to choose any one of the two monitors as a monitor.
