What do patches on your laptop screen mean?

💡 Need to know

• Not every patch means the screen is broken. Smudges, pressure marks, backlight problems, and damaged pixels can look similar at first.
• Pay attention to when it appears. A patch that's visible before Windows or macOS® loads points more toward the display than an app.
• Don't press on the screen. Pressure can make LCD damage worse, even if the patch temporarily changes shape.
• Growing, spreading, or changing colors? That's a stronger sign the display itself may need repair.

Seeing patches on your laptop screen is incredibly frustrating. The patches may get in the way of what you’re looking at on screen or simply be annoying distractions. Either way, you’ll want to get rid of them as soon as possible.

There are several reasons patches may appear, and at Asurion, we’ve seen them all. Our tech experts have learned the best fixes for issues like these while helping millions of customers with their devices. Whether your laptop's patchy screen is due to pressure damage, backlight issues, or another common cause, Asurion is here to help.

Common causes of laptop screen blotches and spots

A cloudy patch on a laptop screen doesn’t just appear randomly. Blemishes often occur when there’s damage to the laptop. Consider whether any of these common causes could be behind the patches on your screen:

• Pressure damage: When part of the screen has been compressed, such as by closing the laptop on items or carrying it in a very tight bag, you may see white, yellow, or dark patches.
• Internal dust or debris: Small particles of dust or other debris trapped between the screen layers can create bright patches on your laptop screen.
• Heat damage: High temperatures can cause the internal adhesives behind the screen to melt, causing yellow patches or other areas of discoloration.
• Moisture: If water or other liquids get into the screen layers, you may see cloudy or white patches on your laptop screen.
• Stuck pixels: Individual or small clusters of pixels that aren’t working properly can create black or colorful spots.
• Aging: As LCD screens age, the liquid crystal layers can break down, leading to a yellow spot on your laptop screen.

Identify the difference between black spots and liquid damage

Liquid damage and dead pixels can both cause patches on a laptop screen. Before fixing a broken laptop screen, you need to know which issue you’re dealing with to choose the best solution.

Look at the patch. If the spot is black, the problem is likely dead or stuck pixel clusters. By contrast, if you see a white or clouded patch on your laptop screen, liquid damage may be the culprit.

For stuck pixels, you may be able to fix the issue with a pixel massage. Turn off your laptop and cover the affected area of the screen with a soft cloth. While turning your computer on, gently massage the screen with a stylus or eraser. Just be aware that too much pressure can make the issue worse.

If there’s internal damage from liquid or pressure, cleaning likely will not help. Try other methods for how to get rid of black spots on Chromebook or other devices if the issue persists.

How to troubleshoot laptop display issues

Whenever you’re having an issue with your laptop, it’s a good idea to check for software updates. You never know when a bug in the software may be to blame. Look for and install any updates that are available.

Also, try checking your laptop drivers. In Windows®, use Device Manager. On Mac®, update macOS® in System Settings.

Update your graphics drivers

Outdated graphics drivers could cause visual artifacts like a bright patch on your laptop screen. Try updating the drivers.

On Windows 10 and 11, follow these steps:

1. Open Device Manager.
2. Click the arrow next to Display adapters to expand the category.
3. Select your graphics card.
4. Choose Update driver.

On Mac, simply install the latest macOS update if one is available.

Test with an external monitor

Connecting your laptop to an external monitor will help you determine whether the problem is your laptop screen itself:

1. Plug the monitor into a power outlet and use a cable to connect it to your laptop.
2. Power on the monitor.
3. If the patches do not appear on the external monitor, there’s likely physical damage to your laptop hardware.

When to consider professional laptop screen repair

Depending on the cause of the patches, you may be able to fix the issue yourself. For example, if debris is causing bright spots, you could open up the laptop and clear the dust.

However, opening a laptop, especially the screen, always comes with the risk of causing more physical damage. A professional has the tools and experience for careful repair. And if there’s any permanent screen damage, such as from heat, liquid, or pressure, you may need a full screen replacement.
