A:Answer OLED TVs have special features and settings to preserve image quality and prevent burn in and image retention. First, under OLED Screen Saver there is the Pixel Refresher that calibrates any issues that may arise on the screen when your TV has been turned on for a long time. Calibration takes more than an hour. The second feature that can be employed is the Screen Shift feature which, moves the screen slightly at regular intervals to preserve image quality. A third option is the Logo Luminance Adjustment, which can detect static logos on the screen and reduce brightness to help decrease permanent image retention. ^Daphane
