Screen burn-in, the persistent ghost image retention on displays, remains a concern particularly for OLED technology users. The most effective prevention methods include utilizing built-in screen saver functions that activate during inactivity, implementing pixel shifting features that subtly move content pixels, maintaining moderate brightness levels especially in static content scenarios, enabling auto-brightness adjustment according to ambient light, regularly refreshing pixel patterns through specialized software, and varying displayed content to avoid prolonged static elements. Modern displays often incorporate these protective measures automatically, but user awareness and proper device settings significantly contribute to minimizing burn-in risks and extending screen longevity across various display technologies including OLED, QLED, and plasma screens. For devices showing early burn-in signs, many manufacturers offer pixel refresh utilities that can help reverse minor image retention through controlled pixel cycling procedures.
