Arcade displays, particularly older CRT and modern OLED screens, are susceptible to screen burn-in - a permanent discoloration caused by static images displayed for extended periods. The most common prevention methods include implementing screen savers that activate during idle periods, utilizing pixel shifting technology that subtly moves the image, reducing overall brightness and contrast settings, scheduling regular power cycling, and employing image inversion features. For arcade operators, rotating game content periodically and using anti-burn-in modes specifically designed for commercial displays can significantly extend screen lifespan. Modern displays often incorporate automatic refresh cycles and built-in compensation technology that help neutralize burn-in effects. Regular maintenance including cleaning and proper ventilation also contributes to preventing image retention issues. For existing mild burn-in, running specialized video content that exercises all pixels evenly can sometimes reverse early-stage damage.
