Screen ghosting in arcade game machines is a common issue, especially with older CRT monitors. To prevent this, regular maintenance is essential. First, ensure proper ventilation to avoid overheating, which can degrade display quality. Adjusting the monitor’s brightness and contrast settings can also reduce ghosting effects. Additionally, using high-quality signal cables and connectors minimizes interference. For long-term prevention, periodic degaussing of CRT monitors helps maintain magnetic field stability. Finally, replacing aging components, such as capacitors, can restore display clarity and prevent ghosting. These methods ensure optimal performance and longevity for classic arcade gaming experiences.
