Screen burn-in is a common issue for arcade machine displays, especially those with OLED or plasma screens. To prevent this, follow these effective methods:

1. Use Screen Savers or Sleep Mode: Enable automatic screen savers or sleep mode when the machine is idle to avoid static images.

2. Adjust Brightness and Contrast: Lowering brightness and contrast reduces stress on pixels, prolonging display life.

3. Pixel Shifting and Refresh: Utilize built-in pixel-shifting features or manually refresh pixels periodically.

4. Avoid Static Images: Rotate game graphics or menus to prevent prolonged display of the same content.

5. Regular Maintenance: Power down the machine when not in use and clean the screen to prevent overheating.

By implementing these practices, you can significantly reduce the risk of screen burn-in and keep your arcade machine displays vibrant for years.
