How to Fix Horizontal Lines on a Computer Screen?

Here are the best ways to get rid of horizontal lines on your computer screen or monitor.

Turn off and on your monitor. It appears to be a simple remedy, but it can frequently correct screen problems such as horizontal lines.
Start your computer again. This can resolve a range of technical issues, including flickering lines on your screen.
Change your monitor. This can assist you in determining whether the lines are caused by your computer’s screen or the computer itself.
Check your monitor while it is turned off. While your monitor is turned on, unplug it from your computer and examine for any flickering or lines on its screen. If you notice any distortion, this indicates that your monitor has been damaged.
Remove and replace the keyboard. If your computer has a removable keyboard, remove it, wait a few seconds, and then replace it.
Reopen and close your laptop. Close your laptop’s screen, wait a few seconds, and then slowly reopen it. Keep an eye out for when the lines appear on the screen as you open it. If the lines appear exclusively at a specific angle, the culprit is most likely broken wiring.
Place your laptop on a flat surface. Overheating can be caused by soft materials, such as a blanket or tablecloth, resulting in screen flickering and lines.
Install any available operating system upgrades. Lines on your computer screen could be caused by old software clashing with newer technology.
Examine the monitor connection. While inspecting the cords, ensure that all cables are securely attached and keep an eye out for any improvements in screen image quality. If you observe that the image improves or worsens when you touch the connected cable, it may need to be replaced.
Remove the monitor. If you’re using an external display, unplug it from your computer for a few seconds, then reconnect it.
Magnets and electronics should be removed. If you have any other electronics or magnetic devices near your computer, screen, or connecting cables, relocate them since they may interfere with the connection and cause the lines.
Clear the dust from your computer and monitor. Dust could be causing your computer and monitor to overheat, causing visual distortions.
Modify the screen resolution. Change the screen resolution on your computer, whether it be Windows or Mac.
Check the calibration of your monitor. This procedure should just take a few minutes and will help optimise your monitor for use with your computer and its surroundings.
Change the refresh rate of your monitor. Changing the refresh rate can assist with lines and screen flickering.
Update the drivers for your devices. Examine driver updates for profiles related to your monitor and screen.
Start a troubleshooter. Run the Video Playback and Programme Compatibility troubleshooters from Settings > System > Troubleshoot > Other troubleshooters. If you are given suggestions for other troubleshooters, run them as well.
Restore your monitor’s factory settings. If you’re using an external monitor or screen, reset it to factory settings using its built-in settings rather than your computer’s. These options are accessible via a physical Settings or Menu button on the computer monitor.
Please contact official support. Inquire with the manufacturer’s customer service regarding a repair or replacement.
Purchase a new computer or monitor. If nothing else works, it may be time to invest in a new computer or a better display.
