Screen burn-in is a persistent issue in arcade machines, particularly those using CRT monitors. The most common causes include static images displayed for extended periods, high brightness settings, and poor ventilation leading to overheating. Classic games with fixed UI elements, such as score displays or health bars, are especially prone to this problem.

To mitigate screen burn-in, arcade operators can implement several strategies:

1. Screen Savers or Attract Modes: Use dynamic animations during idle periods to prevent static images from lingering.

2. Adjust Brightness/Contrast: Lowering these settings reduces stress on phosphors.

3. Regular Screen Refreshing: Periodically changing displayed content helps evenly wear phosphors.

4. Proper Ventilation: Ensuring adequate cooling prevents overheating, which accelerates burn-in.

5. Monitor Rotation: Swapping or rotating monitors distributes wear more evenly.

For severely affected machines, professional CRT rejuvenation or replacement may be necessary. Proactive maintenance remains the best defense against this costly issue.
