Windows 10: Pc spasms in and out of source screen black screen trying to set the display output.

When I connect my hp elite 8300 sff to my samsung 32 inch monitor I am having trouble with the source mode rapidly flickering and trying to stabilize. It is not switching between sources, just seems its trying to connect to the source I am on. This usually occurs after I have been playing or try to load a game. It also occurs when loading browsers and opening folders/files. At times it will constantly flicker in and out of the source mode and I have to restart my pc.


Please help

:)

 

Get a black screen after installation of the Anniversary Update

Hi,

If you’re seeing a black screen, there might be a connection problem with your PC or display.

• If you’re using a desktop PC, check to see if your display is plugged in and turned on. Also, try connecting to different video outputs on your PC. Sometimes a change in driver can cause the video to be sent to a different display adapter or output.
  
• If you have a TV connected to your PC, make sure it's turned on and set to the input for your PC.
  
• Try projecting to a different monitor. Press the Windows logo key + P, press P, and then press Enter. Repeat this step to go through the different screen options.

Black Screen

Hi Tracy,

Thank you for pasting your query in Microsoft Community.

Please follow the below steps to resolve this issue.

We have been seeing black screen issues of several types after upgrading to Windows 10. The main causes observed so far are driver issues, output to unexpected port, and possibly also issues with the Lock Screen app. Please use these steps:

If you see the black screen only after sign-in
and you can see a mouse cursor:

• While at the black screen, try using CTRL+SHIFT+ESC to start Task Manager.
  
• If it becomes visible, try finding LockAppHost.exe on the Details tab and ending the task.
  
  • If this resolves the black screen, use corruption resolution steps (dism, then sfc), and run the all apps PowerShell command in
    
    3080495.
• If this does not work, use File, Run new task in Task Manager to start an Administrator CMD window. Use this to create a new administrator user with the following commands (changing “<password>” to something of the customer’s choosing):
  
  net user test <password> /add
  
  net localgroup Administrators test /add
• This will give you a test user to try, which will confirm if the issue is user or system-specific.

If you see the black screen or have a flickering screen before sign-in:

• Try connecting to different video outputs on the PC. Sometimes a change in driver can cause the video to be sent:
  
  • To a different Adapter: from integrated graphics to a discrete card or vice versa.
    
  • To a different output: from HDMI to DVI, DisplayPort to VGA, or any other combination.
    
• Try to boot into Safe Mode with Networking or Enable low-resolution video.
  

• • Advanced boot options, Safe Mode with Networking, or Low Resolution Video
    
  • Check Device Manager and look for Display Adapters
    • If you see 2 items under Display Adapters, disable to integrated video card (e.g. Intel HD 4000 or AMD Radeon HD 4200) and restart. (try vice versa if it does not work)
      
    • If you see 1 item under Display Adapters, rollback the driver or uninstall the display adapter in Device Manager, and enable the option to delete driver software.
      

Check the PC or display adapter manufacturer’s site for an updated driver.

Hope the information helps to fix the issue, if you have any further queries, feel free to post. We are here to assist you.

Regards,
