A static image or its outline will stay on the screen even after its gone. Examples are: News Banners, Icons, or Video Game User Interface Items
If a static image is displayed on the screen of Alienware OLED Gaming monitors for an extended period without changing the video, using a screensaver, or turning the monitor off, Image Retention (Burn In) can occur.
To reduce temporary Image Retention on the screen, manually activate the Pixel Refresh function after using the monitor for a couple of hours. Alternatively, the function is activated automatically when the monitor is used for at least four hours. The process takes approximately 6 to 8 minutes to complete.
To prevent permanent Image Retention caused by static content when you use the monitor for at least 1,500 hours, manually activate the Panel Refresh function to refresh the pixels. Alternatively, the function is activated automatically when the accumulated usage time exceeds the factory default setting (1,500 hours). The process takes approximately an hour to complete.
