6. Maintenance

To ensure the longevity and optimal performance of your UGREEN KVM Switch, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the exterior of the device. Avoid using liquid cleaners or abrasive materials.
• Storage: Store the KVM switch in a cool, dry place away from direct sunlight and extreme temperatures.

7. Troubleshooting

If you encounter issues with your KVM switch, please refer to the following common troubleshooting steps:

• No Display/Signal:
  • Ensure all HDMI cables are securely connected to both the KVM switch and your devices (computers and monitor).
  • Verify that the correct input source is selected on your monitor.
  • Check the resolution and refresh rate settings on your computers. The KVM switch supports up to 4K@60Hz. Higher refresh rates (e.g., 144Hz, 180Hz) at resolutions like 1080p or 2K may not be supported.
  • Try using shorter, higher-quality HDMI cables, especially for 4K@60Hz, as per the cable length guidelines in Section 5.1.
• USB Devices Not Working:
  • Ensure the USB A to B cables are firmly connected between the KVM switch and both computers.
  • Verify that the KVM switch is receiving adequate power via its USB-C power input. Connect it to a reliable 5V 1A power source.
  • Test the USB devices directly with the computer to confirm they are functional.
  • Try connecting USB devices to different USB ports on the KVM switch.
• Switching Issues:
  • Ensure the physical button or desktop controller is pressed firmly.
  • If using the desktop controller, check its connection to the KVM switch.
• Intermittent Connection:
  • Ensure all cables are properly seated and not loose.
  • Check for any potential electromagnetic interference from other devices.
  • Verify that the KVM switch is receiving stable power.

8. User Tips

• Dedicated Power: For optimal performance and to ensure all USB devices function correctly, especially power-hungry ones like external hard drives, always connect the KVM switch to a dedicated 5V 1A USB-C power adapter, even if your host device provides power.
• Cable Quality: Invest in high-quality HDMI 2.0 cables, especially for 4K@60Hz resolutions, to prevent signal degradation and ensure stable video output. Refer to the cable length guidelines in the specifications section.
