How to use

Place the KVM switch on a stable surface near the computers to be controlled and the shared peripherals.

Attach a single keyboard and mouse to the switch’s USB ports, and connect the HDMI output to the shared monitor. Apply the 5V DC power supply to the unit. Use the front panel controls or switching mechanism to select the active computer; peripherals and video will switch accordingly. Ensure cables are securely seated to avoid signal interruptions.

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.
