Setting up dual monitors involves connecting the monitor to the computer, then configuring the operating system to display on dual monitors. If the operating system used is Windows 7, there are several methods of configuring dual monitors.
- Determine if the computer has a second port
The majority of modern graphics cards support multiple monitors. Even if the graphics card does not have a second port, many on-board graphics support additional monitors. Look on the back of the computer to determine if it accommodates multiple monitors.
- Plug in the second monitor
Turn off the computer and run the cable from the second monitor to the back of the computer. Plug in the cord and make sure it is secure. Turn on the computer and both monitors.
- Configure the display settings
If the operating system is Windows 7 or 8, right-click on the desktop, then click on Screen Resolution. Click on the Multiple Displays drop-down list, and select either Extend These Displays, which will make your display extend over all the monitors that are set up, allowing you to have different applications open on each monitor, or Duplicate These Displays, which shows the same display on both monitors. If the additional monitors are not showing up, click on Detect.
