Symptoms

Microsoft Windows 10 supports multiple monitor set up. A multiple monitor set up helps enhance productivity. When you connect an additional monitor to your Dell computer, Windows 10 automatically detects 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.

Cause
NOTE: Dell OptiPlex 3040 or 3046 with an add-on VGA port can only support two external monitors at one time using the native Intel Graphics solution.

Ensure that the video connector on the computer matches with an available video connector on the monitor, like VGA, DVI, HDMI, DisplayPort (DP), or USB-C (that supports DisplayPort or Thunderbolt 3).

Determine the type of video connector that is available on the computer and the monitor. The number of available video connectors depends on the type of graphics card that is installed in the computer. Most desktop graphics cards support two or more monitors, depending on the graphics card and computer specifications. However, laptops can support up to two monitors depending on the computer specifications. To learn more, see the Dell knowledge base article How to Connect a Monitor to a PC.

NOTE: To identify the video connectors that are available on the computer and monitor, see the User Guide of the computer and the monitor.

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.

Microsoft Windows 10 provides multiple display style options on how the desktop screen is displayed across multiple monitors that are connected to the computer. In 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. 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.
  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.
NOTE: When you connect a second monitor to a Dell laptop, the default display style is set to Duplicate mode. When you connect a second monitor to a Dell desktop, the default display style is set to Extend mode.
