Arcade machines often integrate with external displays or marquees to enhance the gaming experience or modernize classic setups. Most arcade cabinets support external monitors via VGA, HDMI, or DVI connections, depending on the system's hardware. For marquees, LED or backlit panels are commonly used, connected through dedicated power and signal cables.

Modern arcade PCBs (printed circuit boards) and emulators allow flexible display configurations, enabling dual-screen setups for dynamic gameplay and artwork. Custom marquees often use USB-powered LED strips or replaceable acrylic panels for easy updates.

Key considerations include voltage compatibility, mounting hardware, and software settings to ensure smooth synchronization. Whether retrofitting vintage cabinets or building custom arcades, integrating external displays requires careful planning for optimal performance and aesthetics.
