8. Troubleshooting

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

1. No Display on Monitor:
   • Ensure the KVM switch is powered on using the provided DC 12V adapter.
   • Verify that all HDMI cables are securely connected between the computers, KVM switch, and monitor.
   • Confirm that the correct input source is selected on your monitor.
   • Try using certified HDMI 2.1 cables, especially for high resolutions (8K/4K@144Hz).
   • Restart the KVM switch and the connected computers.
2. Keyboard/Mouse Not Responding:
   • Ensure the USB 3.0 cables are securely connected from each computer to the corresponding USB 3.0 input on the KVM switch.
   • Verify that your keyboard and mouse are connected to the USB 3.0 peripheral ports on the front of the KVM switch.
   • Try connecting the keyboard and mouse directly to the computer to confirm they are functional.
   • Some specialized gaming keyboards/mice with advanced features may require direct connection or specific drivers not supported by KVM switches.
3. Switching Delay:
   • An approximate 8-second delay during switching is normal as the KVM re-establishes connections. This is not a malfunction.
4. No EDID Information:
   • This KVM Switch does not feature EDID emulation. This means the monitor's EDID information is passed directly to the active computer. When switching, the inactive computers may detect a temporary loss of display, which is normal behavior for KVMs without EDID emulation.

9. Maintenance

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

• Cleaning: Use a soft, dry cloth to clean the exterior of the device. Do not use liquid cleaners or aerosols.
• Ventilation: Ensure the KVM switch is placed in a well-ventilated area to prevent overheating. Do not block any ventilation openings.
• Power: Always use the provided DC 12V power adapter. Using an incorrect power adapter may damage the device.
• Storage: When not in use for extended periods, store the device in a cool, dry place away from direct sunlight and extreme temperatures.
