White spots on screen are a common display issue that can appear on any device — from smartphones to laptops to desktop monitors. Whether you noticed a small bright dot on your MacBook, a glowing patch on your monitor, or white spots appearing on your phone screen, this guide will help you understand what causes white spots, how to diagnose them, and what options you have.
White Spots on Screen: Causes, Test, and Fix Guide
What Are White Spots on a Screen
A white spot on screen is an area that appears brighter than the surrounding pixels. Unlike dead pixels (which are permanently dark), white spots glow or look washed out compared to the rest of the display. They can range from tiny pinpoints to larger cloudy patches.
White spots can appear on any screen type: laptops, desktop monitors, tablets, and smartphones. You might notice them as:
- A small bright dot on your MacBook screen that stands out against dark backgrounds
- A glowing patch in the corner of your monitor that is most visible at high brightness
- White spots on your phone screen that appeared after sitting on the device
- Uneven brightness across your laptop display that creates a visible white area
Not Sure What Type of Spot You Have
Before diving deeper, let us help you narrow down exactly what you are dealing with. The right diagnosis depends on what your spot looks like:

Common Causes of White Spots on Screen
Understanding what causes white spots helps you determine the best course of action.
Pressure Damage
Physical pressure is one of the most common causes of white spots on screen. When strong or sustained pressure is applied to the display, it can damage the internal layers, particularly the backlight layer on LCD panels. The damaged area may fail to block light properly, resulting in a permanent bright spot.
Pressure damage commonly occurs when:
- Closing a laptop with an object on the keyboard
- Sitting on your phone or placing heavy objects on top
- Accidentally pressing too hard on the screen
- Carrying devices in tight spaces with other objects
Backlight Bleeding
On LCD screens, white spots are frequently caused by uneven backlight distribution. The backlight panel sits behind the display and illuminates all pixels from behind. If the adhesive or diffuser layer degrades, or if pressure has affected a specific area, light can concentrate in one spot and create a visible white or bright patch.
Backlight bleeding typically appears as a glowing or cloudy area rather than a sharp dot. It is most noticeable on dark backgrounds and often worsens at higher brightness levels.
Stuck Pixels
A white spot that appears as a small, bright dot that never changes color might be a stuck pixel rather than a backlight issue. Stuck pixels are individual pixels that are stuck on a single color (often white or bright red/green/blue). Unlike dead pixels (which produce no light), stuck pixels are producing light but cannot change.
Stuck pixels can sometimes be fixed with pixel-fixing software that cycles through colors rapidly, applying rapid electrical signals to the stuck pixel.
LCD Defects
White spots can also appear due to manufacturing defects or aging of the display components. Over time, the adhesives, diffusers, and light guides inside a screen can deteriorate, leading to localized areas of abnormal brightness.
In some cases, white spots are caused by delamination — when the layers of the display begin to separate, causing light to scatter in unexpected ways.
What Does Your White Spot Look Like
This is the most important question for diagnosis. The appearance of your white spot tells you exactly what type of issue you are dealing with.
Small Bright Dot
If your white spot is a small, precise dot (typically 1 pixel or a few pixels wide), it is most likely a stuck pixel. The dot will remain exactly the same size regardless of the screen content and will not change position.

Large Glowing Patch
If your white spot is larger and appears as a cloudy or glowing area, especially on dark backgrounds, it is most likely a backlight issue. These patches often have irregular edges and may be more visible at certain brightness levels.

White Spot on Phone
If you have white spots on your phone screen, especially after the device was dropped or sat upon, it is most likely physical pressure damage to the display. Phone screens are particularly vulnerable to pressure damage due to their thin profiles.

White Spots on Different Devices
White spots can appear on any screen type. Here is what you need to know for specific devices.
White Spot on iPhone Screen
iPhone screens can develop white spots from physical pressure, backlight issues, or (rarely) stuck pixels. iPhone displays are OLED on newer models, so white spots on iPhones may have different causes than on LCD screens. If you notice white spots on your iPhone, check our mobile white spots guide for device-specific advice.
White Spot on MacBook Screen
MacBook screens are particularly susceptible to white spots due to their thin profiles and the way they close. White spots on MacBook screens are commonly caused by pressure from closing the laptop with objects on the keyboard, or from physical impacts. Apple has specific warranty policies — check if your Mac is still under warranty if you have white spots.
White Spot on Lenovo Laptop Screen
Lenovo laptops can develop white spots for the same reasons as other brands: pressure damage, backlight issues, or pixel problems. Whether you have a ThinkPad, IdeaPad, or Legion series, white spots can appear at any time. Use the screen test tool to narrow down the cause.
White Spot on HP Laptop Screen
HP laptops can develop white spots from dead pixels, physical damage, or backlight issues. HP screens are found in various models from Pavilion to EliteBook series, and each can potentially develop these defects. Check if your HP laptop is under warranty for potential free repair.
White Spots on Monitor
Desktop computer monitors are not immune to white spots. External monitors can develop backlight bleeding, stuck pixels, or pressure marks just like laptops. A white spot on your monitor may be more noticeable due to the larger screen size. If your monitor is under warranty, contact the manufacturer for repair options.
Quick Diagnosis
Use this quick checklist to narrow down your white spot issue:
If your white spot...
- Does not move or change → Hardware issue (likely permanent)
- Changes color occasionally → Stuck pixel (may be fixable)
- Appeared after pressure or impact → Physical damage (likely permanent)
- Is larger at higher brightness → Backlight bleed (may improve at lower brightness)
- Has irregular, cloudy edges → Backlight or delamination issue
- Is a sharp, tiny dot → Stuck pixel
How to Test for White Spots
The most effective way to detect and diagnose white spots is using a screen test tool with solid color backgrounds:
- Open the Screen Test Tool on your device
- Display solid white background — white spots will be clearly visible as brighter areas
- Display solid black background — backlight issues may become more visible as glowing patches
- Display solid red, green, and blue backgrounds — stuck pixels may appear as a single bright dot in one of these colors
- Increase your screen brightness — faint white spots become more visible
Look for areas that remain permanently brighter than surrounding pixels. Document the location and approximate size of any white spots you find — this information is useful for warranty claims or repair discussions.
Can White Spots Be Fixed
Whether white spots can be fixed depends on their cause. Here is a breakdown of possible fixes and when professional repair is necessary.
What Might Work
- Pixel-fixing apps: These tools cycle through colors rapidly and can sometimes revive stuck pixels by applying rapid electrical signals. Their effectiveness varies and they only work on stuck pixels, not dead pixels or hardware damage.
- Lower brightness: For backlight bleed, reducing screen brightness can sometimes make white spots less noticeable
- Professional repair: If your device is under warranty, contact the manufacturer
What Does Not Work
- Screen massage: There is no scientific evidence that applying pressure fixes white spots. In fact, pressure risks causing additional damage.
- Software updates: White spots caused by hardware issues cannot be fixed through software
- External cleaning: White spots caused by internal damage will not be fixed by cleaning the screen surface
When Repair Is Needed
If the white spot is caused by pressure damage, backlight bleeding, or internal component failure, the only reliable solution is screen replacement. Consider professional repair or replacement when:
- The white spot is in your primary viewing area
- The spot is growing or spreading over time
- The device is still under warranty
- The spot appeared after physical damage and may worsen
How to Prevent White Spots
Prevention is the best strategy for protecting your screen:
- Avoid putting pressure on your screen — do not press hard when cleaning
- Close your laptop gently and ensure nothing is on the keyboard
- Use a protective case for your phone and tablet
- Handle your devices carefully to avoid impacts
- Test new devices before the return window expires
- Avoid sitting on your phone or placing heavy objects on top of it
