Windows 10: Display adapters not recognized after Win 10 update

After installing the 2004 update started 8/6/2020, continuing 8/7, neither of my graphics cards is recognized and my second monitor is not detected. I have fixed this before by deleting the devices in Device Manager and then re-booting. I tried that, and the Windows update was uninstalled. Is this a known issue? Is there a solution. I have an Intel HD graphics display adapter and an nVidea GeForce GT 525M.

Step 1: I suggest you to run SFC scan,
System File Checkeris a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files.

Follow the below steps:

• Right click on the Start button, click on
  Command Prompt (Admin).
• Type “sfc /scannow” without the quotes and hit
  Enter.
• After the scan, restart the computer and check for the issue.

Step 2: Also, I suggest you to update the display drivers and check.

Steps to Update the Display Adapter driver.

• Press Windows key + Xkey when you are at desktop.
• Select Device Manager.
• Expand Display Adapter.
• Right on the Display Adapter and click on
  Update driver software

BUT i still have the line on screen.

 

Display adapter issue after updating from 7 to 10

Hi Marty,

Thank you for using Windows 10.

I understand your concern and would suggest you to try performing "Startup Repair" and check if that helps. Here is the steps:

• Press and hold Shift key and click on Restart
  from login screen.
• Click on Troubleshoot.
• Select Advanced Options.
• Select Startup Repair and follow the on screen instructions.
  

If the issue doesn't get resolved, use these steps:

• 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.

• • Press and hold the shift key while clicking on Restart
    at the login Screen (Bottom right corner) > Troubleshoot>
    Advanced Options> Startup Settings> Restart >>Choose
    Enable Safe mode with networking.
    
    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.

Let us know the updated status and we'll be glad to help.
