@Jaylin3 -- How am i supposed to do that when my all in one has only an out hdmi port?

Your All-In-One has both an internal screen, and one HDMI-output port.

It was designed to allow you to add a second screen, without deactivating the internal screen.

Try connecting a HDMI-to-HDMI cable from the HDMI-output port on your computer to the HDMI-input port on your external monitor.

Then, on your computer, use that "Windows-P" command to "extend" the Windows desktop onto the 2nd monitor.

What happens when you try this?

To continue our conversation, when you have two functioning monitors, namely the internal screen of the All-In-One, and the external screen connected via the HDMI cable, Microsoft Windows can designate either screen as the "#1" screen. The other screen becomes the "#2" screen.

If you click with the right-side mouse-button anywhere on the Windows "wallpaper", you can choose to open a window similar to:

On your system, you will see two rectangles, and you can "drag-and-drop" the two rectangles, to match the physical positioning of your two screens (is the HDMI screen on the left, or on the right of the All-In-One?) and you can designate either screen as the "primary" screen.

Try this:

1. take an HDMI cable, and connect it to  the HDMI socket on your computer and also to the HDMI-input port on your external monitor
2. use the monitor's OSD (On Screen Display) buttons to de-select "VGA-input", and to select "HDMI-input"
3. on your keyboard, hold-down the "Windows" key (bottom-left of your keyboard) and tap once on the "P" key. On the menu that appears, choose "extend"
4. on your computer, click with the right-side mouse-button anywhere on your computer's "wallpaper" background image
5. select "Display Settings"
6. scroll-down to "Multiple Displays"
7. click "Detect", to see which screen Windows considers to be "#1" and which screen is "#2"
8. from this window, you can select that your Spectre monitor is to become the "primary" output from Windows.

OK?
