Burn-In Test & Reduction
Detect image retention or screen burn-in on OLED and LCD displays by observing solid colors and grayscale patterns. Use the reduction mode to help erase temporary ghosting.
Test Patterns
What is Screen Burn-In?
Screen burn-in (or image retention) is a visible discoloration or ghosting of a previous image that remains on the screen even when the display is showing something else. It typically occurs when a static image (like a UI element, taskbar, or logo) is displayed continuously for long periods.
Permanent Burn-In vs. Temporary Image Retention
It is important to understand that not all "burn-in" is permanent:
- Permanent Burn-In (OLED/CRT): Caused by uneven degradation of the sub-pixels. If you leave a bright static image on an OLED screen for hundreds of hours, the pixels emitting that image age faster and permanently lose their brightness, leaving a ghost image. This cannot be fixed.
- Temporary Image Retention (LCD/IPS): Caused by liquid crystals losing their alignment due to prolonged electrical charge. This looks identical to burn-in, but is entirely reversible by playing varied content or using a burn-in reduction tool.
How to fix image retention?
If your display is suffering from temporary image retention, playing a highly dynamic, randomized video signal can help reset the liquid crystals. Our built-in "Burn-In Reduction" mode generates full-screen static (white noise), which is extremely effective at exercising the panel and erasing temporary ghosting.
How to Use Burn-In Reduction
Our tool generates high-frequency white noise (TV static) that forces every subpixel on your screen to rapidly change states. This effectively exercises the panel and can clear temporary image retention. For best results, run the tool at maximum screen brightness for 30 to 60 minutes.
