Screen Burn-In Test

Screen-Burn-in-Test

Screen burn-in is permanent damage to the display that occurs after static images remain on the screen for a long time after they change to silhouette. This causes accelerated degradation of certain pixels. This mainly affects OLED and plasma displays, as their light-emitting components age unevenly.

To check Screen burn-in use our Defective Pixels and Uniformity test on test panel.

To start each test, click the “►” button with your mouse.

To stop the test at any time, simply press the Esc key on your keyboard.

What can cause screen burn-in?

screen burn-in example

Common causes of screen burn include:

  • Displaying static images or logos extensively;
  • Leaving screens on pause or on channels with continuous graphics;
  • Using high screen brightness settings;
  • Engaging in long gaming sessions with static HUD elements.

How to Detect Screen Burn-In

To check for burn-in on your display:

  1. Display a solid color, typically gray, across the entire screen – use our Defective Pixels and Uniformity test on test panel;
  2. Look for any persistent images, discoloration, or uneven areas.

Many modern devices come with built-in pixel refresher tools designed to help mitigate minor burn-in issues.

Preventing Screen Burn-In

While some degree of pixel ageing is inevitable, the following steps can be taken to minimise the risk of noticeable burn-in:

  1. Pixel Refresh or Screen Shift Tools: Many modern displays, especially OLED TVs and smartphones, have built-in settings designed to refresh the screen and shift static content slightly to even out the wear on pixels.
  2. Use Static Images Less Frequently: To prevent further burn-in, try to avoid leaving static images on the screen for extended periods. Use features like screen savers, auto-turnoff, or sleep settings to ensure the screen isn’t displaying the same image for too long.
  3. Lower Brightness Settings: Keeping your screen brightness at a lower setting can reduce the rate at which pixels degrade.
  4. Fill Screen Tools: Some online tools and apps can cycle through full-screen colors to possibly help equalize the wear on the display.
  5. Professional Repair: In cases where the burn-in is particularly bad, professional repair might be necessary. This could involve replacing the screen, which can be costly.

Is it possible to fix?

Once screen burn-in has occurred, it is usually permanent and cannot be completely fixed. You can sometimes reduce its visibility using pixel-refresh features or color cycling tools if your device supports them. These methods attempt to even out the wear on the display but do not guarantee the removal of burn-in. Replacing the screen is often the only effective solution.

Impact on Different Display Types

OLED Displays: Highly susceptible to burn-in due to their self-emitting pixels, which degrade independently, causing uneven wear.

LCD Displays: Generally less prone to permanent burn-in but may show temporary image retention that typically resolves on its own (check our screen retention test).

Plasma Displays: Although similar to OLEDs in vulnerability, modern plasma screens have better resistance against burn-in.

Assess your monitor's ability to accurately reproduce similar colors while maintaining their distinction. To do this, create two color patches. The closer the similarity between the two colors, but the more distinguishable they are, the higher the monitor's color resolution. This score is especially useful for comparing the color reproduction capability of two different monitors directly.
