7. Troubleshooting

• No Display Output:
  • Ensure all HDMI and DisplayPort cables are securely connected to both the KVM switch and your monitors/PCs.
  • Verify that the KVM switch is powered on and the correct PC input is selected.
  • Check monitor input settings to ensure they are set to the correct HDMI/DisplayPort input.
  • Try using different HDMI/DisplayPort cables, especially high-quality DP1.2 and HDMI 2.0 cables.
  • Restart the KVM switch and connected PCs.
• USB Devices Not Working:
  • Ensure the USB 3.0 cables from your PCs are connected to the corresponding USB 3.0 INPUT ports on the KVM switch.
  • Verify that your USB devices are properly connected to the USB 3.0 ports on the front of the KVM switch.
  • Try connecting the USB device directly to the PC to confirm it is functional.
  • Some high-power USB devices may require external power or a powered USB hub.
• Resolution Issues / Flickering Screen:
  • Ensure your graphics card drivers are up to date on all connected PCs.
  • Verify that your monitors support the desired resolution and refresh rate.
  • Use certified DP1.2 and HDMI 2.0 cables, especially for 4K@60Hz. Longer or lower-quality cables can cause signal degradation.
  • For HDMI connections, the EDID emulation should help maintain stable resolution. For DisplayPort, manual adjustment might be needed if issues persist.
• Switching Delays:
  • A slight delay during switching is normal as the KVM re-establishes connections.
  • Ensure all cables are securely connected. Loose connections can cause inconsistent switching.

• Cleaning: Use a soft, dry cloth to clean the exterior of the device. Avoid using liquid cleaners or abrasive materials, as they may damage the surface or internal components.
• Ventilation: Ensure the KVM switch is placed in a well-ventilated area to prevent overheating. Do not block any ventilation openings.
• Storage: When not in use for extended periods, store the device in a cool, dry place away from direct sunlight and extreme temperatures.
