Windows 10: Laptop crashes after unplugging external monitor

I have a Dell laptop that the screen died on and it's ok while my external monitor is connected. However when I unplug the monitor to use it with another device the pc will crash. I'm not sure if it crashes immediately or when I try to connect the montior again. Only way to recover is hard reset. No issues shown in device manager.

Laptop suddenly stopped recognizing the external monitor

Hi,

Thank you for posting your query in Microsoft Community.

To assist you better, I would like to ask if the laptop is unable to recognize only the external monitor or other external devices also.

I suggest you to run the Hardware and Devices troubleshooter by following the steps below:

• Click on the Start button, and type “Troubleshooting” on the search bar.
• Click on “Hardware and Devices”.
• A pop-up will appear, click on the “Next” button and your hardware troubleshooting will start.
  

Hope the information is helpful. Keep us posted on the status for further assistance.

 

No display on laptop's external monitor-Monitor recognized but blank

After the recent Windows 10 update, my wife's laptop no longer displays on the external monitor. All was well before the update.

I am comfortable that Windows sees the monitor because clicking on Display Settings shows two displays. If I unplug the HDMI cable, only one display is shown.

I have confirmed that the monitor works by trying it with another laptop. I have also changed the HDMI cable between the laptop and the external monitor.

Device manager reports that I have the latest display driver installed.

I would appreciate any and all suggestions.

 

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
