Windows 10: Applications opening on monitor that is not available

My computer is showing I have 4 monitors, but I only have 3. I have searched how to remove the 4th ghost monitor, but the options I've tried do not work.Solution 1 - Right-click and remove any excess generic PnP monitors from Devices and Printers in Control Panel.Response - I tried that, but my settings / control panel is opening on the 4th monitor. I can see it in the taskbar and when I hover over the icon, I can see the window is open, but I can't access it.Solution 2 - ALT + Tab to go between windowsResponse - nope. Doesn't work.Solution 3 - Close all windows and shut down

Applications Not Opening on my External Monitor

Hello,



Thank you for writing to Microsoft Community Forums.



As you are able to view the desktop and task bar on the external monitor, I suggest you to drag the applications from the laptop screen on to the external monitor and check the result.



However, Windows 10 will open the applications on the primary monitor.

Windows retains the position of the application that is opened, if the application is opened and dragged to the secondary monitor, upon closing the application and reopening it. The application will open on the secondary monitor.



Hope it helps.

Open a Program on any Monitor where I open at?

Hi,

Regardless of how many monitors are set up on a computer, one main display is allowed. For your security, we cannot offer any third-party applications that are not approved by Microsoft.

Alternatively, you can follow the steps below on how can an application open in a specific monitor:

• Open an application, then drag it to the monitor you want it to open.
• Restore down the application (window mode). To do so, press the Windows
  key + the Arrow down key on your keyboard.
• Close the application by clicking the X mark icon.
• Relaunch the application to confirm.

Note that this workaround may or may not work for all applications.

Feel free to post back if you need further assistance.

 

Applications Not Opening on my External Monitor

I have a Toshiba Satellite laptop running Win 10. I have a Samsung external monitor attached via HDMI.

My background display and task bar DO appear on the external monitor, but when I open applications such as Outlook, Google Chrome, etc., they open on the laptop screen NOT on my external monitor.

I have shutdown both the laptop and external monitor and rebooted. The external monitor is listed in Device listing. I have the display setup for Extended Desktop and when I select Identify, it shows me 1 as the laptop and 2 as the external monitor.
I have unplugged both ends of the HDMI cable.

How do I get apps to open on my external monitor? Thanks for any assistance. Cheryl
