How To Fix Mac Horizontal Lines On Screen?

To fix horizontal lines on the screen, you should wipe off the screen with a soft cloth. You can also clean the screen with a dry microfiber cloth. After cleaning the screen, let it air out for 15 minutes. Then, restart the computer and try opening programs. If the issue persists, you can replace the battery.

You can also use a laptop stand to keep your laptop upright and prevent it from touching anything. A laptop stand keeps the screen away from the keyboard and prevents accidental touches. If you discover a small problem with your device, then you can repair it yourself however, you should seek the help of a pro if the damage is extensive.

Horizontal lines on the screen are caused by a number of reasons. Some of them include dust particles, scratches, fingerprints, water droplets, etc. These issues can occur at any point during usage and can be fixed using simple methods.

If none of these solutions work, you can purchase a new screen. However, it might not be worth the cost since the issue usually occurs due to a minor scratch.

What Causes These Horizontal Lines On My Screen?

Horizontal lines on your MacBook Pro’s screen may be caused by a number of issues. One common issue is a bad connection between the video card and the motherboard. Another possibility is a damaged video card. You should try to fix these problems yourself before contacting Apple Support.

To begin troubleshooting, start by checking whether there is a problem with the cable connecting the video card to the motherboard. If you find that the cable is loose or broken, replace it. Next, look at the video card itself. Is it damaged? Finally, check the connections between the video card and its power supply. Are they properly seated?

If none of those solutions works, then you’ll probably need to call Apple support.

Guidelines For Fixing Horizontal Lines On Your MacBook Display

On the MacBook Pro line of computers, Apple uses two different types of screen resolution displays: Light-Emitting Displays (LEDs) and Liquid Crystal Displays (LCDs).

Many MacBook Pro owners are complaining about the appearance of horizontal stripes on their devices. These issues are most likely caused by a hardware issue. Here are some suggestions for fixing them:

Reset the SMC

There are two types of MacBook models available in the market today. One has a T2 chip, which means it has a built-in security feature called Secure Memory Controller. The other one does not have a T2 chip, meaning it doesn’t have any kind of security feature.

To reset the SMC of a MacBook that has a T2 Chip, follow the steps mentioned above. However, if the MacBook doesn’t have a T2 chip then follow the steps given below.

First, shut down the computer. Then, hold the left Control and Shift keys, and the Option key on the left side of the keyboard. Next, hold down the laptop Power button until the Apple logo appears on the screen. Finally, let go of all the keys and wait for approximately ten seconds. After waiting for ten seconds, turn on the computer.

Now, there are two methods to reset the SMC of the MacBook without a T2 chip. The first method involves holding down the Shift key and the Command key simultaneously. The second method requires holding down the Shift key, the Command key, and the Option key simultaneously.

After following either of the two methods, restart the computer.

Reset NVRAM

To begin, you’ll need to restart your MacBook. Then, hold down Command + Option + P + R until you hear the startup sound twice. Release the keys once you’ve heard the startup sound for the second time. Finally, let go of the keys after the Apple logo appears and disappears for the second time.

With the models having a T1 chip, you’ll need to keep this in mind before letting go of the keys, after when you hear the startup sound for the third time.

You should now be able to resolve the issue. However, if you still experience problems, try using the alternative method below.

Alternative Way To Address The Problem

There are two methods to address the horizontal lines and vertical lines issue on your MacBook. One involves pressing the control key along with Shift and Eject. The second method involves putting your Macbook to sleep, waiting until it wakes up, and then pressing any key button from the Keyboard to wake it up.

Both methods work, but the second method requires less effort. You’ll only need to press any key button from your keyboard to wake your laptop from sleep mode.

This method works great if you’re using a MacBook Pro, but not if you’re using a Mac mini. Because the Mac mini doesn’t have a separate power button, you won’t be able to use the second method to fix the stubborn lines issue.

Add An External Screen

If you’re experiencing horizontal lines on your MacBook Pro, there are two possibilities: either your display logic board is faulty or your graphics card is at fault.

To find out which option is correct, simply plug in an external monitor to your laptop and observe whether the same horizontal lines appear on the new screen. If they do, then it’s most likely an effective display issue. However, if the lines don’t appear on the external monitor, it means that your graphics card is at blame.

Either way, you should contact an Apple service center to fix the problem.

Conclusion

There are several guidelines that you should keep in mind when fixing horizontal lines on your MacBook. First, you’ll need to determine whether the issue is caused by hardware or software.

Hardware problems include damaged screens, broken hinges, cracked LCD panels, and dead pixels. Software problems include corrupted files, malware infections, and outdated operating systems.

Once you’ve determined the source of the problem, you can either fix it yourself or hire a professional to do it for you. You can fix most hardware problems yourself, but if the damage is extensive or requires specialized equipment, you should call a professional.
