Color shifting in arcade displays, particularly in classic CRT-based units, is a common issue that can significantly impact gameplay experience and visual quality. The most effective prevention methods begin with regular degaussing, a process that eliminates magnetic field buildup causing color distortion. Using either the built-in degaussing circuit or an external degaussing coil helps maintain color purity by neutralizing these magnetic fields.

Proper monitor calibration is equally crucial. Adjusting the color guns, brightness, and contrast settings using test patterns ensures accurate color representation. Environmental control plays a key role—keeping displays away from speakers, power supplies, and other electromagnetic interference sources prevents external magnetic fields from affecting color performance.

Regular maintenance of monitor components, particularly capacitors, prevents color drift caused by aging electronics. Implementing voltage regulation protects against power fluctuations that can cause color instability. For permanent installations, proper grounding and isolation from vibration help maintain consistent color performance over time.

Routine visual inspections and periodic professional servicing ensure early detection of potential issues before they develop into significant color problems. Combining these methods provides comprehensive protection against color shifting in arcade displays.
