Arcade displays, particularly classic CRT monitors, are prone to discoloration over time without proper care. The most effective prevention methods begin with environmental control - keeping arcade cabinets away from direct sunlight and fluorescent lighting that accelerates phosphor decay. Regular degaussing remains crucial for neutralizing magnetic field interference that causes color distortion; most quality arcade monitors feature built-in degaussing circuits that activate at startup.

Implementing moderate brightness and contrast settings significantly reduces phosphor burn-in, while using screen savers or attract modes during extended inactivity prevents static image retention. For permanent collections, installing UV-filtering acrylic over the screen provides protection without affecting visibility. Professional color calibration using industry tools like the Sencore ColorPro or CR7000 ensures accurate color reproduction when performed annually.

Routine maintenance should include checking capacitor health in the monitor chassis, as failing capacitors directly impact color stability. Proper ventilation prevents heat buildup that accelerates component degradation. For serious collectors, implementing a rotation schedule between play and rest periods extends display lifespan. These preservation techniques maintain the vibrant colors that define the authentic arcade experience while protecting valuable vintage hardware.
