Burn-in Fixer
Attempt to reduce temporary image retention (ghosting) on IPS and OLED panels using rapid color changes and high-contrast patterns. Cannot reverse permanent physical burn-in.

Understanding Image Retention vs. Burn-in
When a static image (like a taskbar, channel logo, or HUD in a video game) is displayed for long periods, you may notice a ghost-like silhouette left behind. It is important to distinguish between temporary image retention and permanent physical burn-in.
On IPS and TN panels, this is often "Image Retention" caused by a build-up of parasitic electrical charge within the liquid crystals. This is generally temporary. On OLED and AMOLED screens, persistent static images can cause the organic materials to degrade unevenly, leading to permanent "Burn-in".
How this tool may help with temporary retention: By forcing the screen to cycle through primary colors or display high-contrast white noise, this tool essentially exercises the pixels. It forces rapid voltage state changes, which may reduce the appearance of temporary charge build-up. Permanent physical burn-in will remain.
FAQ
Is OLED burn-in permanent?
Yes. True OLED burn-in is physical degradation. This tool is designed to help with temporary image retention (ghosting). It cannot reverse permanent physical burn-in.
Which pattern should I use?
For stuck pixels (a bright green or red dot), use the Rapid Color Cycle. For image retention or ghostly silhouettes, the White Noise (Static) pattern is often preferred.
Will my screen turn off during the test?
We try to keep the screen awake using the Web Wake Lock API where supported. If your device doesn't support this feature, you will need to temporarily disable auto-lock in your system settings.
