Recommendations

For reliable operation, use high-quality HDMI and USB cables of appropriate length to minimize signal degradation. Place the KVM switch in a well-ventilated location and avoid exposure to moisture or extreme temperatures. When switching frequently between systems, allow a brief pause for the operating system to re-detect USB peripherals after a change. Regularly inspect connectors and cables for wear to maintain consistent performance.
