How to Use 2 Monitors in Windows 7
Windows 7 was released by Microsoft in 2009 and includes support for two or more monitors, depending on the video hardware installed in the computer. Each display can be configured independently. Each display can have separate settings such as screen resolution and color depth. Some video cards include support for up to six monitors. You can set up Windows 7 to use two monitors through the Screen Resolution settings, which is accessible from the desktop.
Connect the second display to the computer and turn it on.
Right-click an empty area of the desktop and click "Screen Resolution."
Click the "Detect" button to ensure the second monitor is detected by the computer.
Click the screen mode under "Multiple Displays." Choose "Duplicate these displays" to show the same image on both screens or "Extend these displays" for each monitor to be independent.
Click the icon for the second monitor and drag it to represent the physical layout of the screens. For example, if the second monitor is physically to the left of the main monitor, drag the icon of the second monitor to the left side of the icon of the main monitor.
Click "OK" to finalize the settings.
Tips & Warnings
- Two more settings are under "Multiple Displays." The settings are to show the desktop only on one monitor or the other. This defeats the purpose of having two or more monitors connected, and is not recommended for use.
