Spots on your display appear as persistent marks that remain in the same position regardless of what is displayed. This guide explains the different types of spots, their causes, and what you can do about them.

Display Spots: Fix Black, White, and Colored Spots on Screen

Understanding Spots on Display

Spots on display are localized areas of the screen that appear different from the surrounding pixels. Unlike smudges on the screen surface, display spots are permanent features visible through all content. They can appear as black spots, white spots, bright glowing spots, or colored spots.

The key characteristic of display spots is their fixed position. Regardless of which application is open or what is displayed, the spots remain in the same location. This distinguishes them from temporary artifacts that move with content.

Types of Display Spots

Black Spots

Black spots appear as small dark areas that remain black regardless of the background color. They are typically caused by dead pixels - individual pixels that have completely stopped producing light. A cluster of dead pixels forms a larger black spot.

White Spots

White spots are bright areas that glow more than surrounding pixels. They are usually caused by backlight pressure - when pressure on the back of the display causes light to concentrate in a specific area. White spots are most visible on dark backgrounds.

Colored Spots

Spots that appear in specific colors (typically blue, green, or red) may indicate sub-pixel damage. These spots result from damage to individual color sub-pixels within the LCD structure.

Pressure Spots

Pressure spots appear after physical impact or pressure has been applied to the screen. They may appear white, colored, or as clusters of dead pixels. The damage may be immediately visible or may develop over time.

Common Causes of Display Spots

Dead Pixels

Dead pixels occur when the thin-film transistor (TFT) controlling a specific pixel fails completely. The pixel produces no light, appearing as a permanent black dot. Multiple dead pixels in an area create larger black spots.

Backlight Pressure Damage

In LCD displays, the backlight illuminates the screen from behind. Pressure on the display (from closing a laptop with an object on the keyboard, for example) can cause the backlight to concentrate light in specific areas, creating bright white spots.

Physical Impact

Physical impacts from drops or hits can damage the display panel's internal structure, causing spots that may be white, black, or colored depending on the type of damage sustained.

Manufacturing Defects

Some spots appear due to manufacturing defects in the display panel. These are typically covered under warranty during the initial period and may be eligible for replacement.

Moisture and Liquid Damage

Liquid exposure can cause spots to appear on the display as moisture damages internal components. These spots may spread over time as the damage progresses.

How to Diagnose Display Spots

Step 1: Use the Screen Test Tool

The most effective way to diagnose spots is with our screen test tool:

1. Open the Screen Test Tool
2. Display pure white background - note all visible spots
3. Display pure black background - white spots will glow, black spots will disappear
4. Display red, green, and blue backgrounds - colored spots become more apparent
5. Document the location, size, color, and visibility of each spot

Step 2: Identify the Spot Type

Based on the screen test results:

• Black on all colors: Dead pixels or clusters of dead pixels
• White on dark backgrounds: Backlight pressure spots
• Colored spots: Sub-pixel damage or panel defects
• Spots that change appearance: Possible temporary issues (warm up, cool down)

Step 3: Check for Patterns

Note if spots follow any pattern:

• Linear spots may indicate cable or connection issues
• Corner spots often result from physical impact
• Center spots may indicate pressure from mounting
• Edge spots can result from hinge pressure in laptops

How to Fix Display Spots

Dead Pixel Spots

Dead pixels cannot be revived through software or home remedies. Options include:

• Living with the spot if it is small and in an edge area
• Checking warranty coverage for dead pixel policies
• Professional screen replacement for larger spots

White Spot Damage

White spots from backlight pressure are difficult to fix at home:

• Some users report mild improvement from gentle pressure techniques
• Professional repair may be able to relieve backlight pressure
• Screen replacement is the most reliable fix

Prevention is Key

The best approach to display spots is prevention:

• Never close your laptop with objects on the keyboard
• Handle portable devices carefully to avoid impacts
• Keep screens clean to avoid scratching
• Use protective cases for laptops and tablets

Testing Your Display Regularly

Regular screen testing helps catch spots early:

1. Use the Screen Test Tool monthly
2. Test with all primary color backgrounds
3. Compare results over time to detect any changes
4. Check new devices immediately upon purchase

Conclusion

Spots on display are permanent visual defects that cannot usually be fixed through software or home remedies. Understanding the type of spot (black, white, or colored) helps determine the likely cause and whether the issue may be covered under warranty. Regular screen testing helps detect spots early, and careful handling of devices prevents most spot damage. If spots are large, spreading, or significantly affecting your use of the device, professional repair or screen replacement may be the best option.
