If you see vertical lines on your screen, know that something may happen that needs your immediate attention. Sometimes the fix is easy and simple, and other times fixing vertical lines would require some troubleshooting.

If your monitor has horizontal or vertical lines after applying pressure to the screen, or if the lines appear the least bit times except when applying pressure to the screen, there’s usually an issue with the LCD panel. A faulty LCD screen would cause this issue, but it may also be caused by the graphics adapter. Make sure all cables are connected securely. Even loose connectors can cause various picture issues, including gray, pink, or green lines.

How To Fix Green Lines On Monitor?

After ensuring there is no cable fault and everything is perfectly in place, here are some possible solutions to fix green lines on monitor. However, get professional assistance or replace your monitor for smooth usage if these solutions won’t help you fix the problem.

Adjust Your Screen Resolution

A screen resolution adjustment may help you fix green lines on a monitor. If the device picture settings aren’t compatible with the monitor’s native resolution, you will see errors like green lines on the screen.

Setting a display resolution or refresh rate that’s not supported can damage a monitor that will not even be repaired. It can also be a real threat with older CRT monitors, so you better be careful, check all the display settings, and take corrective actions. You can also solve your issue with various other techniques.

Via Battery Release

  • Power down your PC and unplug all peripherals.
  • If you’re using a laptop, take its battery out by reversing it the wrong way up and sliding the battery release latch.
  • Press and hold the facility button for 15 or 20 seconds to clear all residual power from the system.
  • Reconnect everything and switch the system back on to test if the annoying green lines are gone.

Via Factory Setting

  • Unplug the monitor from the PC and wait a few seconds until it displays a message “No signal.”
  • If the no signal message also has vertical lines, you can easily recognize the matter is within the monitor and not in your computer.
  • Therefore, Press the “Menu” button on the screen, then use the opposite buttons to browse for a “Factory Settings” mode.
  • Select this mode to reset the monitor to its original settings.
  • If the lines persist, the monitor may be dropped or be exposed to a magnet — which can’t be fixed.

Via Display Quality

  • Press Windows + R from your device, type electrical device, then press OK.
  • Click View through within the right-hand corner and choose Large Icons
  • Select Troubleshooting
  • After this, Navigate to the left pane and click on the View All option, where you need to select Display Quality
  • Enter the password for admin or grant when prompted.

Via Graphic Driver

To check your issue with the help of a graphic driver, you need to Right-click on the beginning and button choose the Device Manager option. Here you need to seek graphics or video card drivers with a yellow punctuation mark, down arrow, or error message. If the driving force encompasses a  yellow punctuation mark, double-click it and Open Properties. On the driving force behind the force tab, select Update Driver and Restart your computer.
