Are you seeing vertical lines on your Macbook Screen? If so, then don’t worry—it’s a common issue that can have several causes. Fortunately, there are several steps you can take to fix this issue yourself.

First, reboot your Mac. This is a simple solution that can help with many temporary issues and system glitches. If that doesn’t work, check your cable connection to make sure it’s properly secured. You can also try connecting another display to see if the lines appear on that screen too.

If these steps don’t work, then you may need to reset the SMC (System Management Controller) or NVRAM (Non-Volatile Random Access Memory). To do this, turn off your computer and hold down the keys “Command+Option+P+R” before turning it back on again.

You should also make sure your graphics card drivers are up-to-date as outdated drivers could be causing this issue. You can find and install updated drivers from the manufacturer’s website or through Apple System Updates.

Finally, if none of these steps work then you might need to reinstall the current macOS version or take your computer in for repairs.

No matter what the cause of vertical lines on your Macbook Screen is, make sure to follow these steps so you can get back up and running as quickly as possible!

Fixing Vertical Lines on a Mac

If you’re seeing vertical lines on your Mac screen, there are a few steps you can take to try and resolve the issue.

First, reboot your Mac. This can help with many temporary issues and system glitches. If this doesn’t work, check the cable connection between your Mac and the display. You may want to try connecting to another display to see if the lines are still present.

Next, reset the System Management Controller (SMC) and Non-Volatile RAM (NVRAM). To do this, shut down your Mac and then press and hold the Shift+Control+Option keys along with the power button until your computer restarts.

If these steps don’t work, try installing any available graphic card updates or reinstalling the current version of macOS. If all else fails, you may need to take it in for repair or contact Apple Support for help troubleshooting the issue.

Investigating Vertical Lines on a MacBook Pro Screen

Vertical lines on a MacBook Pro can be caused by several possible issues. One of the most common is an outdated graphics card driver. If you’re seeing lines, it’s a good idea to check your graphics card driver and make sure it’s up to date. You can do this by going to the support page for your device and downloading the latest version of the driver. Additionally, if the issue persists, it could be related to a hardware problem such as a damaged display cable or loose connections. It may also be a result of accumulated dust or debris in the display, which can be cleaned with compressed air. In any case, we recommend seeking professional help if you’re unable to resolve the issue yourself.

Removing Glitched Lines From a Screen

If you are seeing glitched lines on your screen, the first thing to do is restart your device. This can often fix minor glitches and resolve any issues with the display. To do this, press and hold the volume button for a few seconds until the reboot menu appears. Select the “Restart” option and let your phone complete the process.

If restarting doesn’t work, then you can try to access safe mode to see if the problem persists there. To do this, press and hold the power button until you see the manufacturer logo appear, then release it and press and hold it again until you see a list of options. Choose “Safe Mode” from this list and let your phone boot up in safe mode. If the lines are still present in safe mode, then it’s likely that an app is causing them to appear on your screen. Try uninstalling recently installed apps one by one until you find which one is causing the issue.

If that doesn’t solve the issue either, then it may be time to take your device to a technician for further inspection and repair.

If you suspect physical damage to be the cause, please contact a qualified technician for further assistance.

Identifying the Causes of Vertical Lines on a Screen

Vertical lines on computer screens can be caused by a variety of factors. One of the most common causes is outdated or faulty graphics card drivers. If the driver is out of date, it can cause the video display to malfunction, resulting in vertical lines appearing on the screen. Other possible causes include defective ribbon cables, incorrect video cable connections, damage to the screen itself, and even a problem with the monitor’s power supply. Additionally, a weak signal from an external device such as a laptop or game console can also result in vertical lines on the screen. To diagnose the issue, it’s best to check for any loose connections or defective hardware that could be causing the issue before attempting to update drivers or replace parts.


In conclusion, Macbook screen issues such as horizontal and vertical lines can be caused by a variety of factors.
