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

1. Use Screen Savers: Activate a screen saver when the machine is idle to avoid static images from burning into the display.

2. Enable Pixel Shifting: Many modern displays have this feature, which slightly moves the image to prevent prolonged static content.

3. Adjust Brightness and Contrast: Lowering these settings can reduce the risk of burn-in over time.

4. Rotate Content: Change game graphics or menus periodically to avoid persistent static elements.

5. Turn Off When Not in Use: Powering down the machine when inactive helps extend screen longevity.

By following these steps, arcade owners can significantly reduce the risk of screen burn-in and maintain vibrant displays for years.
