• Turn your monitor off and on again. It seems like a basic fix, but it can often correct any screen glitches, such as horizontal lines.

• Restart your computer. A quick restart can fix a variety of tech issues and could get rid of any flickering lines on your screen.

• Try a different monitor. If possible, try connecting to a different monitor or screen. It can help you determine if the lines are caused by your computer’s screen or the computer itself.

• Check your monitor while it’s disconnected. Keep your monitor powered on, unplug it from your computer, and look for any flickering or lines on its screen while it’s disconnected. If you see any kind of distortion, this means that your monitor is damaged.

• Detach and reattach the keyboard. If you have a computer that uses a removable keyboard, remove it, wait a few seconds, and reattach it.

• Close and reopen your laptop. Close your laptop’s screen, wait a few seconds, and reopen it again slowly. Look to see when the lines begin to appear on the screen as you open the laptop. If the lines only occur at a certain angle, the cause is likely damaged wiring.

• Use your laptop on a hard surface. Soft surfaces such as on a blanket or tablecloth can cause overheating, resulting in screen flickering and lines.

• Install the latest operating system updates. Old software conflicting with newer hardware could cause the lines on your computer screen.

• Check the monitor connection. Ensure all of the cables are securely connected, and watch for any improvements in screen image quality while you’re inspecting the cables. If you notice the image improves or worsens while touching the connecting cable, it may need replacement.

• Disconnect the monitor. If you’re using an external monitor, disconnect it from your computer, wait several seconds, and reconnect it.

• Remove magnets and electronics. If you have other electronics or magnetic devices near your computer, screen, or the connecting cables, move them somewhere else as they may interfere with the connection and cause the lines.

• Clean your computer and monitor. Dust may be causing your computer and its monitor to overheat and create visual distortions.

• Change the screen resolution. Whether using a Windows or Mac computer, try changing its screen resolution.

• Calibrate your monitor. This process should only take a few minutes and can help optimize your monitor for use with your computer and its environment.

• Change your monitor’s refresh rate. Switching to another refresh rate setting can help with lines and screen flickering.

• Update your device drivers. Check for driver updates for profiles associated with your monitor and screen.

• Run a troubleshooter. Open Settings and select System > Troubleshoot > Other troubleshooters and run the Video Playback and Program Compatibility troubleshooters. If you get presented with any recommendations for other troubleshooters, run those too.

• Reset your monitor to its factory settings. If you’re using an external monitor or screen, use its built-in settings, not your computer’s settings, to reset it to its factory settings. You can usually access these settings via a physical Settings or Menu button on the computer monitor itself.

• Contact official support. Contact the support for your computer’s manufacturer and inquire about a repair or replacement.

I will try those out once I'm done with school, thank you. I will write an update

Hi,

You could try connecting to an external monitor/TV with HDMI cable and check whether you get the lines in it as well, also try reinstalling the display adapter driver from Acer support site for both Intel and NVIDIA(if you have)

Also, switch or change the refresh rate and check the problem is solved or not.———————————————————————————————
