Windows 10: Bluetooth disappears after disconnecting from external monitor

I have a dell xps 13 2 in 1 2019 and i use a vava usb c dongle to connect to an external monitor and keyboard. When I safely remove the device and unplug the usb c dongle the screen flashes black for a second and after that weird stuff happens. The most common problem is that the bluetooth disappears until shut down the machine restart will not work. Less common, the entire pc will crash when i unplug. Also, sometimes everything is fine, but shouldn’t that always be the case? Am i doing something wrong or are there drivers i need to update? Thanks!

Primary monitor blacks out after disconnecting from external

Hi Oscar,



Thank you for writing to Microsoft Community forums.

• Are you aware of any changes that happened on the computer prior to this issue?
  

This issue could be due to the display setting corruption that only affected the primary display when disconnected from the secondary.



I suggest you to try the steps listed below and check if it works for you:

• Press ‘Win + R’ keys on the keyboard together to open the Run dialog box and type the following into the Run box:
  appwiz.cpl
  
• Uninstall Intel HD Graphics Drivers and exit
  Programs and Features.
  
• Right click the Windows icon on the taskbar and choose
  Device Manager.
  
• Expand Display Adapters and right click on
  Intel HD Graphics Display Driver.
  
• Click on Uninstall and check the box
  Delete the driver software for this device.
  
• With the external monitor connected, reboot the machine.
  
• Once the machine boots into the desktop, disconnect the external monitor and check if the issue persists.
  

Hope it helps.

Regards,

External Monitor with Quicken

Hi Mark,

It is possible that the display resolution automatically adjusts after connecting to an external monitor. For us to properly isolate this issue, we have some questions for you:

• Are you experiencing the same issue even without using the Quicken tool?
• Have you checked if the display resolution settings of the Surface device and the external monitor is the same?
• Have you tried checking for a graphics device driver update?
• What troubleshooting steps have you done to isolate the issue?
  

We're looking forward to your response.
