How to Fix a Pixelated Screen on a Mac: Easy Troubleshooting Steps

If you’re experiencing a pixelated screen on your Mac, it can be frustrating and greatly affect your productivity. However, before rushing to the nearest tech store or contacting Apple support, there are several easy troubleshooting steps you can try on your own. In this article, we will walk you through these steps, helping you identify and resolve the issue, so you can get back to enjoying a clear and crisp display on your Mac.

Adjust Screen Resolution Settings

Adjusting the screen resolution settings is often the first step in resolving a pixelated screen on a Mac. Incorrect or unsupported screen resolution can cause the display to appear blurry or pixelated. Here’s how to do it:

1. Click on the Apple menu in the top-left corner of the screen and select “System Preferences.”
2. In the System Preferences window, click on “Displays.”
3. Navigate to the “Display” tab and check the available resolutions.
4. Select the resolution that matches the native resolution of your display or the one that provides the sharpest image.
5. Apply the changes and check if the screen appears clearer.

If the pixelation persists, try different resolutions to find the most suitable one for your screen. It’s worth mentioning that using a non-native resolution may result in a slightly less sharp image. However, if none of the available resolutions solve the issue, consider trying the other troubleshooting steps mentioned in this article.

Update Graphics Driver Software

Updating the graphics driver software on your Mac can often resolve issues with a pixelated screen. Graphics drivers are responsible for controlling the display output and optimizing the performance of your graphics card. Outdated or incompatible graphics drivers can cause pixelation and other display problems.

To update the graphics driver software on your Mac, follow these steps:
1. Click on the Apple menu in the top-left corner of the screen and select “System Preferences.”
2. Choose the “Software Update” option. This will check for any available updates for your Mac, including graphics driver updates.
3. If updates are available, click on the “Update Now” button and follow the on-screen instructions to install them.

In addition to updating through the System Preferences, you can also visit the website of the graphics card manufacturer to manually download and install the latest driver software for your specific graphics card.

Updating the graphics driver software may require a system restart. After updating, check if the pixelation issue has been resolved. If not, you can try the next troubleshooting step.

Check For Software Updates

Updating your software is an essential step in fixing a pixelated screen on your Mac. Software updates often include bug fixes and improvements that can address issues affecting your display. Here’s a brief guide on how to check for software updates:

1. Click on the Apple menu located on the top-left corner of your screen.
2. Select “System Preferences” and then click on “Software Update.”
3. The system will check for any available updates. If there are updates available, click on “Update Now” to begin the installation.
4. You may be prompted to enter your administrator password to authorize the update.
5. Wait for the updates to download and install. This process may take some time, so ensure that your Mac is connected to a stable internet connection.

Regularly checking for software updates is crucial as it ensures that your Mac is running the latest version of macOS, which can help resolve various display-related issues, including pixelation. Keep in mind that it’s also advisable to enable automatic software updates to stay up-to-date effortlessly.

Clear Temporary Files And Cache

Clearing temporary files and cache can often help to resolve a pixelated screen issue on your Mac. Temporary files and cache accumulate over time and can cause various display problems, including pixelation. Here is a step-by-step guide on how to clear these files:

1. Open the Finder on your Mac.
2. In the menu bar, click on “Go” and select “Go to Folder.”
3. Type in “~/Library/Caches” (without quotes) and press Enter.
4. A new window will open, showing a list of cache files.
5. Select all the files in the cache folder and move them to the Trash.
6. Empty the Trash to completely remove the files from your system.

Additionally, you can also clear temporary files by using a trusted cleaning software like CleanMyMac or CCleaner. These programs can automatically scan and remove unnecessary files, improving system performance and resolving display issues.

By clearing temporary files and cache, you can eliminate any corrupted or outdated files that may be causing pixelation on your Mac’s screen. This simple troubleshooting step should be one of the first actions to take when encountering display problems.

Scan For And Remove Malware Or Viruses

One of the potential causes of a pixelated screen on a Mac could be malware or viruses infecting the system. These malicious programs can disrupt the normal functioning of the computer, including the display. To resolve this issue, it is essential to scan and remove any malware or viruses that may be present.

Begin by using a reliable antivirus software to perform a thorough scan of the Mac. Make sure the antivirus software is up to date to ensure it can detect the latest threats. If any malware or viruses are detected during the scan, follow the instructions provided by the antivirus software to remove them.

Additionally, consider using an anti-malware program specifically designed for Mac systems. These programs are built to tackle Mac-specific threats and provide an extra layer of protection.

Regularly updating the antivirus software and performing scans can help prevent future infections and ensures that the Mac remains free from malware or viruses that could potentially cause a pixelated screen.

Test The Screen With A Different Cable Or Port

When encountering a pixelated screen on your Mac, it is essential to test the screen with a different cable or port. Sometimes, the issue may be related to a faulty cable or a damaged port, which can cause the screen to appear pixelated. By using a different cable or connecting the Mac to a different port, you can determine whether the problem lies with the current cable or port.

Start by disconnecting the existing cable from both the Mac and the display. Then, replace it with a new cable or use a different port on your computer. Make sure to securely connect the cable to both devices.

Once connected, observe the screen to see if the pixelation issue persists. If the screen appears clear and crisp with the new cable or port, then you have identified the problem and can replace the faulty cable or continue using the alternate port.

If the pixelation problem continues with the new cable or port, it may indicate a different underlying issue with your Mac or software, and it may be necessary to explore other troubleshooting steps.

Reset The NVRAM And SMC

Resetting the NVRAM (Non-Volatile Random-Access Memory) and SMC (System Management Controller) can often resolve issues with a pixelated screen on a Mac. Both NVRAM and SMC store crucial settings for your Mac’s hardware and peripherals. Resetting them can help resolve various display-related problems, including pixelation.

To reset the NVRAM, shut down your Mac and then turn it back on. Immediately hold down the Option, Command, P, and R keys simultaneously until you hear the startup sound for the second time. This will reset the NVRAM.

To reset the SMC, shut down your Mac and unplug the power cord. Wait for at least 15 seconds and then plug it back in. Wait for another 5 seconds and turn on your Mac.

Resetting the NVRAM and SMC can clear any corrupted settings that might be causing the pixelation on your screen. After the reset, check if the pixelation issue persists. If it does, you can proceed to contact Apple Support for further assistance.
