Screen flicker in arcade displays can ruin the gaming experience, but there are several effective methods to prevent it. First, adjusting the monitor's refresh rate to match the game's output can eliminate flicker caused by mismatched signals. Second, ensuring proper grounding and stable power supply reduces electrical interference. Third, using high-quality capacitors and other components in CRT monitors prevents voltage fluctuations. Fourth, regular maintenance, such as cleaning connectors and checking for loose wires, helps maintain stable performance. Finally, modern arcade setups can benefit from LCD replacements, which are inherently flicker-free. By applying these techniques, arcade operators can ensure smooth, flicker-free gameplay for enthusiasts.
