Windows 10: Why does my monitor keep disconnecting from my computer?

For about the last year or so I’ve had this issue with my computer where it will randomly just disconnect with my monitors both HDMI and DisplayPort cables. It doesn’t matter if I’m gaming, doing homework, or just browsing the internet, nothing will stop my computer from just disconnecting from my monitor. The computer doesn’t turn off and I can still hear the sound, but if I want to use my computer I have to reboot it and then it works again. I thought the problem was with my GPU, so I sent it back to the warranty people for them to look over, and they said it was all good. But I’ve been us

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,

Windows 10 Update - Now my dual monitors do not work

Hi,





One of the possible reasons why Windows 10 was unable to detect your dual monitor is an outdated or incompatible graphics driver. To best address your concern, we need you to answer the following questions:

• Which Windows 10 build are you using?
• Have you already tried performing the troubleshooting steps suggested by
  Mauro Cavallin on June 16, 2017?
• Are both of the monitors not working just like what the original poster was experiencing? If yes, have you tried disconnecting one of the monitors? What was the outcome?
• What troubleshooting steps have you done so far?

We will be waiting for your response.
