Symptoms

Microsoft Windows 11 and Windows 10 support multiple monitor setup. A multiple monitor setup helps enhance productivity. When you connect an additional monitor to your Dell computer, Windows 11 and Windows 10 automatically detect the monitor and displays the desktop screen of the computer. You can then choose how you want the desktop screen to appear and customize the display settings such as the display style to clone mode, extended mode, first screen only, or second screen only, screen resolution settings, and color depth.

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

Windows 11 and Windows 10 provide multiple display style options on how the desktop screen is displayed across multiple monitors that are connected to the computer. In Windows 11 and Windows 10, press the Windows key + P key to bring up the display style menu, and then select a display style that best suits your needs.

1. Personal computer Screen only - Use only display 1 and show nothing on display 2. The second monitor is ignored, and only the primary monitor is used.
2. Duplicate (also called Clone mode) - Show the entire desktop on both displays. The second or other monitors mirror the primary monitor.
3. Extend - Stretch the desktop across the two displays. The desktop screen of the computer is extended across all the detected monitors.
4. Second Screen only - Use only display 2 and show nothing on display 1. The primary monitor is disabled, and only the second monitor is used.
