Screen burn-in is a common issue in arcade game machines, especially those with OLED or plasma displays. To prevent this problem, here are the most effective methods:

1. Use Pixel Shifting: Many modern displays feature pixel shifting, which slightly moves the image to prevent static pixels from burning in.

2. Enable Screen Savers: Activate a screen saver or sleep mode when the machine is idle to avoid static images lingering too long.

3. Adjust Brightness and Contrast: Lowering brightness and contrast can reduce the risk of burn-in, especially in high-use environments.

4. Rotate Content: Regularly change the displayed content or game to ensure no single image stays on-screen for extended periods.

5. Implement Scheduled Breaks: Allow the screen to rest periodically by turning it off or displaying a blank screen for short intervals.

By following these practices, arcade operators can extend the lifespan of their machines and maintain vibrant display quality.
