Windows opens programs on a second monitor, that is not connected

I have a Dell XPS13 laptop. When on my desk, I use a second monitor through a docking station (USB3 Kensington). However, when I undock and go mobile, Windows insists on opening programs on the second monitor, even though it is no longer there and the settings
shows that the system knows it is disconnected. I can see the "open" program in task switcher, and I get all the usual options to Snap, Move to desktop etc., I just can't see the program window on my actual laptop screen.

To fix this, the only thing I have found is to connect to another monitor, and move the window onto the laptop screen, then disconnect the monitor. Most inconvenient, especially whn on a train!!

How can I prevent this, or at least move the windows to my main screen when it happens, without a second monitor to connect to. Please note, I am NOT talking about a virtual desktop, but a physical monitor.

 

Windows 10 does not recognise second monitor

Hi Raffaele,

For us to sort out this problem with your dual monitors, we'd like to gather more information about what happened so we can address the issue appropriately. Below are a few questions we'd like to ask:

• Does the monitor on the laptop work if you disconnect the other monitor?
• Is the second monitor connected to the laptop using a DVI, HDMI, or DisplayPort cable?

While waiting for your feedback, we suggest that you disconnect the second monitor from the laptop and check if its own monitor is working. If not, restart the laptop and check again.

Update us with the result.

Regards.

 

Windows 10 does not recognise second monitor

• Does the monitor on the laptop work if you disconnect the other monitor?
  • No. It only works if I disable the driver so that it reverts to the Basic Microsoft driver. But then it will not connect to the external monitor.
  • Driver details for Intel(R) HD Graphics 520
    • Driver version: 21.20.16.4505
    • Driver date: 19/08/2016
  • 
    I also tried to update this driver to no avail so I rolled it back.
    
• Is the second monitor connected to the laptop using a DVI, HDMI, or DisplayPort cable?
  • It is connected via an HDMI cable.
• 
  Is it possible that the update/roll back process left remnants of the program in the Registry etc and these are interacting in a way to stop the proper functioning the graphics? Just a thought. When I did the update it asked me if I wanted it installed in
  the existing drivers folder? I said yes. Was this the right thing to do?
  
• When I disconnected the screen as you asked the laptop display remained blank. Restarting had no effect. As I said above, at the moment the only way I can activate the laptop display is disable the Intel driver and revert to the Microsoft Basic Driver but
  then I can't connect to the external screen.
