How to use

Connect each computer's HDMI output to one of the CM664 HDMI inputs and plug required USB peripherals into the USB-A ports on the switch. Attach the monitor, keyboard and mouse to the corresponding console outputs. Use the device's input selection control to switch active video and peripheral connections to the chosen computer. Ensure the switch has power if an external adapter is provided and confirm each connected computer recognizes the shared keyboard and mouse after switching.

Usage recommendations

For stable video and peripheral performance, use high-quality HDMI cables and ensure USB devices are compatible with shared switching. Place the unit in a location with easy access to the input selection control and manage cable routing to avoid strain on connectors. If audio is required, verify whether the connected HDMI sources and monitor support audio pass-through and adjust system settings as needed.
