Dual monitors not being detected. Mirroring instead.

[Rhysc]

Hi there, 

I was wondering if anyone can help me. I've just plugged another screen into my all in one computer but instead of detecting the display it is just mirroring my main screen. 

It is plugged in through HDMI (because this model does not have VGA ports). I've been searching forums and other options but can't find any solutions. 

Am I doing something wrong or can you suggest a way to fix this? Or perhaps the all in ones cannot have dual display? 

thank you!

Hey there! @Rhysc, Welcome to HP forums.

I understand you have issues connecting the monitor to your PC.

Don't worry I'll try to help you out.

Did you make any changes to the monitor?

Have you tried checking with a different HDMI cable?

As you mentioned when you connect the monitor to your PC you just get a mirrored image instead of extended display.

You can try pressing Fn+F5 key together on your PC to select the mode of display you like. If you need extended display you can select extended from the list.

Use the following instructions to either extend or duplicate the desktop with a second monitor:

1.Right-click anywhere on the desktop.

2.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.

3.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.

4.(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.

5.When done, click Apply.
