All-in-one computer, two displays

[Allyouneed]

I have an all-in-one device with an HDMI output port.  If I purchase another monitor, can I split the image between the two displays or will I only be able to duplicate the image?

Hi @Allyouneed,

Welcome to the HP Support Community

I understand you want to know if you can split the screen or only duplicate the screen. To answer your question: Yes you will be able to extend the screen and use both displays at the same time(Split). 

Use the following instructions to either extend or duplicate the desktop with a second monitor as per your preference:

• Right-click anywhere on the desktop.
• Click Display Settings.
• If only one monitor is showing in the window, first verify that the connections are secure between the monitors and the computer. Then, click Detect. If Windows does not recognize both monitors, click Identify. The numbers 1 2, or 3 are shown on the monitor icons to help you identify the monitors.
• If Display, Resolution, Orientation, or Multiple displays selections in the Screen Resolution window are dimmed, not allowing you to make the desired changes, see; Configuring the display with the display driver.
• Use the Multiple displays drop-down list to select one of the following options:
• Duplicate these displays: Show the entire desktop on both displays. 
• Extend these displays: Stretch the desktop across the two displays.
• Show desktop only on 1: Use only display 1 and show nothing on display 2.
• Show desktop only on 2: Use only display 2 and show nothing on display 1.
• (Optional) To change the direction of the desktop extension (usually left or right to match how the displays are physically positioned), select a monitor and drag it to the desired position.
• When done, click Apply.
