How to Fix a Monitor That’s Flickering Green?

Here are the effective troubleshooting steps to help you solve this issue. 

1. Assess the Cables and Connections

Your monitor is connected to a PC or CPU through HDMI, VGA, or DisplayPort. When these ports become loose or faulty, they can cause flickering on your monitor.

To assess if the issue is with the connections, you may unplug the cables from ports and clean them before plugging them in again. This time, make sure to lock the cables in place on both ends.

If this doesn’t make any difference, try to plug the cables into other working monitors or PCs to test if they’re working well. You can also use a working cable to see if it gets rid of the green flickering on your monitor.

If none of these attempts works, then the problem is with the monitor and not the cables.

2. Update Your System Files

A well-working system file is needed for the system to function properly. When it’s corrupted, this can also cause disturbance on your monitor, such as flickering green lines or spots. 

To identify the corrupted system files and repair them, follow the guide below:

  1. Right-click the “Start menu icon on the lower left side of your monitor.
  2. Tap on “Windows PowerShell (Admin).
  3. Tap on “Yes” to allow changes on your device.
  4. Type this command and make sure to include the spaces: DISM /ONLINE /CLEANUP-IMAGE /RESTOREHEALTH.
  5. Press “Enter.
  6. Stand by for a few minutes until the command completely loads.
  7. Close the tab and check if it has fixed the issue.

3. Adjust the RGB

RGB or red, green, and blue is a system that represents the colors used in computer displays. Sometimes, when a disturbance like flickering green appears on the monitor, changing the RGB to Full or Limited does the trick.

  1. Right-click the “Start” icon, then choose “Settings.
  2. Tap on “Sounds and Screen.

  5. A small window will pop up, giving you options to choose full or limited RGB
  6. For the monitor, it’s best to click on Full whenever available.
  7. Now, close the tab and see if it clears the flickering green on your monitor.

4. Update the Display Driver

An outdated display driver is one of the possible culprits for monitors flickering green. Usually, getting the latest version of your graphic card driver can solve that nagging issue.

Before updating the display driver, you may start your monitor in safe mode and then follow the steps below:

  1. Right-click the “Start” icon.
  2. Then, tap on “Device Manager.” 
  3. Double-click “Display adapters.”
  4. Right-click “Existing adapter” and hit “Uninstall device.
  5. Check the one that says, “Delete the software for this device” then hit “Uninstall.
  6. Restart your PC.
  7. After restarting, right-click on the “Start” icon again and open “Settings.
  8. Select “Update & security” then, “Windows Update.
  9.  Watch out for available updates and install them. 
  10. This should get rid of the flickering green on your monitor.

5. Disable the Windows Reporting Services

There are instances when disabling the windows reporting services helps eliminate flickering lines on monitors. You can try this too if the steps above don’t work.

Here’s how this one works:

  1. Right-click the “Start” icon.
  2. Select “Run.
  3. Type the command “msconfig” on the small dialog box that’ll appear, then click “Enter.

  6. Scroll down to locate the “Windows reporting services” and then uncheck to disable it.
  7. Look also for “Problem reporting solution” and uncheck it as well.
  8. Now, click the “Apply” and “OK” options to confirm the changes.
  9. Close the tab and restart your monitor. Hopefully, this one will work on your device.
