This is a small App I created to help fix image retention or ghosting issues (true burn-in is permanent damage and impossible to fix) that can occur when a static image is displayed on a screen for a long period of time and leaves a residual ghost of that image on the screen afterwards. It's a common issue especially on older Plasma displays but also to some degree on newer LCD, LED and even OLED displays.
The usual culprits of image retention are:
- TV or Computer menus
- Black bars (letter box or pillar box)
- Closed captioning area
- TV channel watermark
Basically this App runs full-screen, playing an endless randomized "TV snow/TV static" pattern. Running this app for several hours can refresh the phosphors and even has the added benefit of possibly fixing dead/stuck pixels. It is recommended to leave a display OFF for several hours prior to attempting to fix image retention.
