Windows 10: On System Wake Screen Flickers with Message about Wrong Resolution

Been having this problem for a while now and it is starting to cause other issues. When I wake up the computer from being asleep usually a key press and try to start typing my password right away both my monitors will go black. They will then start to flicker on and off and on the main display it will display a message when it is on saying that the resolution needs to be 1920 x 1080 x 60hz. The computer becomes unresponsive at this point.Both monitors are the same Dell U2424H which run at 1920 x 1080 x 60hz and I have tried connecting them through HDMI as well as the Mini DisplayPort.

Screen flicker

Hi Gordon,

Thank you for posting the query on Microsoft Community.

I am sorry to know that screen is flickering on Windows 10.

Do not worry, will assist you with the issue.

I suggest you to try the steps provided below.

If you see the flickering 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).
• 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 flickering screen before sign-in:

1. 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.

2. 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 this helps in resolving the issue. If the issue persists, do get back to us. We will be happy to assist you.
