6. Troubleshooting

• No Display on Monitors:
  • Ensure all video cables (HDMI, DisplayPort) are securely connected between the computers, KVM switch, and monitors.
  • Verify that each computer's graphics card has the required 2 DisplayPort and 1 HDMI output.
  • Check if the KVM switch is powered on and the correct input (PC1-PC4) is selected.
  • Try restarting the KVM switch and the connected computers.
• USB Peripherals Not Recognized:
  • Ensure the USB 3.0 cables are connected from each computer to the corresponding USB 3.0 input on the KVM switch.
  • Verify that the USB 3.0 cables are functioning correctly.
  • Try connecting the USB peripherals directly to the computer to confirm they are working.
• Remote Control Not Working:
  • Check the battery in the remote control.
  • Ensure there are no obstructions between the remote control and the KVM switch's IR receiver (or the IR Extend cable).
  • Make sure the IR Extend cable is properly plugged into the 'EXT IR' port.
• Intermittent Signal/Flickering:
  • Ensure you are using high-quality HDMI 2.1 and DisplayPort 1.4 cables, especially for 8K/4K high refresh rate resolutions.
  • Verify that the 12V power adapter is providing stable power to the KVM switch.
  • Reduce cable lengths if possible, especially for high-resolution signals.

7. 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. Do not use liquid or aerosol cleaners.
• Ensure proper ventilation around the unit to prevent overheating.
• Avoid dropping or subjecting the device to strong impacts.

8. User Tips

• Cable Quality: For optimal performance, especially with 8K@60Hz or 4K@144Hz resolutions, use high-quality, certified HDMI 2.1 and DisplayPort 1.4 cables. Cable length can also impact signal integrity; shorter cables are generally better for higher resolutions.
• Dedicated USB 3.0 Cables: Remember that each computer needs to be connected to the KVM switch with its own USB 3.0 cable for USB peripherals to be recognized and function correctly.
• Graphics Card Requirements: Confirm your computer's graphics card has the necessary 2 DisplayPort and 1 HDMI outputs to support the triple monitor setup.
• Power Stability: The included 12V power adapter is crucial for stable operation, especially when multiple high-bandwidth devices are connected. Ensure it is always connected.
