Me and My Dell For Inspiron, G-Series, XPS, and Alienware computers

Once the cables are connected securely, your computer should automatically detect and display the desktop screen on the connected monitors. You can now select the display style that best suits your needs.

Microsoft Windows provides multiple display style options on how the desktop screen is displayed across multiple monitors that are connected to your PC.

• PC Screen only—Use only display 1 and show nothing on display 2. The second monitor is ignored and only the primary monitor is used.
• Duplicate (also called Clone mode)—Show the entire desktop on both displays. The second or other monitors mirror the primary monitor.
• Extend—Stretch the desktop across the two displays. The desktop screen of your PC is extended across all the detected monitors and enables you to have a desktop screen that spans across all monitors.
• Second Screen only—Use only display 2 and show nothing on display 1. The primary monitor will be disabled and only the second monitor will be used.
