Adding a second monitor to your computer can improve your overall computing experience. A second monitor will increase the screen real estate of the desktop. This means that you can have more files, programs and folders open without constantly flipping back and forth through the open windows to find what you are looking for. You can configure the second monitor in Windows using the Display Settings feature. The computer must also have an available video port to support the second monitor.

Step 1

Connect the second monitor to your computer. Insert the connection cable, such as a USB cable, into an available connection port on your computer.

Step 2

Click "Start" followed by "Control Panel," then select "Appearance and Personalization" from the list of options.

Step 3

Click "Connect to an external display" under the "Display" section. The "Change the appearance of your display" page will open.

Step 4

Click the "Identify" button to display which monitor is represented in the window. The monitors are identified by the numbers "1" and "2." If the second monitor is not displayed, press the "Detect" button and the system will automatically detect the monitor and display it in the window.

Step 5

Click the drop-down list box next to "Multiple displays," then select "Extend these displays." The desktop on the original monitor will extend to the second monitor, essentially merging the monitors. You will be able to use both screens as a single desktop.
