9. Troubleshooting

If you encounter issues, please refer to the following common troubleshooting steps:

• No Display on Monitor:
  • Ensure all HDMI cables are securely connected between the KVM switch, monitor, and computers.
  • Verify that the selected input on the KVM switch corresponds to an active computer.
  • Test the monitor and HDMI cables directly with a computer to rule out external issues.
  • Ensure the KVM switch is receiving power.
• Keyboard/Mouse Not Responding:
  • Confirm that the USB-A ends of the KVM cables are connected from each computer to a USB port on the computer.
  • Try connecting the keyboard/mouse to different USB OUT ports on the KVM switch.
  • Ensure the keyboard and mouse are standard USB devices. Some specialized gaming keyboards/mice with extra features may require direct connection or specific drivers.
  • Restart the KVM switch and the connected computers.
• Intermittent Signal/Flickering:
  • Check HDMI cable lengths. For 4K@60Hz, HDMI 2.0/2.1 cables should be under 3 meters (10 feet).
  • Ensure cables are high-quality and not damaged.
  • Reduce the display resolution or refresh rate temporarily to see if the issue persists.
• Switching Issues:
  • Ensure the remote control batteries are not depleted and that there is a clear line of sight to the IR receiver.
  • Test switching using the front panel buttons and the wired desktop controller to isolate the issue.
  • Some operating systems, particularly Linux, may require a brief moment to re-detect peripherals after switching.
• One KVM Cable Not Working:
  • Test the problematic cable with a different computer or KVM input port to determine if the cable itself is faulty.
  • Ensure both the HDMI and USB connections of the KVM cable are properly seated.

10. Maintenance

• Keep the KVM switch in a cool, dry place away from direct sunlight and heat sources.
• Clean the device with a soft, dry cloth. Avoid using liquid cleaners or solvents.
