Switching Between Computers

The GREATHTEK HDMI KVM Switch offers two methods for switching:

• Front Panel Button: Press the corresponding button (PC1, PC2, PC3, or PC4) on the front panel of the KVM switch to select the desired computer. The LED indicator next to the button will illuminate to show the active computer.
• Wired Desktop Controller: Use the included wired desktop controller. Press the button on the controller to cycle through the connected computers. This allows for convenient switching without reaching for the KVM unit itself.

Maintenance

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

• Cleaning: Use a soft, dry cloth to clean the exterior of the device. Avoid using liquid cleaners or aerosols, which may damage the unit.
• Ventilation: Ensure the KVM switch is placed in a well-ventilated area to prevent overheating. Do not block any ventilation openings.
• Cable Management: Keep cables organized and free from kinks or excessive bending to prevent damage and ensure stable connections.
• Environmental Conditions: Avoid exposing the device to extreme temperatures, humidity, or direct sunlight.

Troubleshooting

If you encounter issues with your KVM switch, refer to the following common problems and solutions:

• No Display Output:
  • Ensure all HDMI cables are securely connected to both the KVM switch and the computers/monitor.
  • Verify that the KVM switch is powered on.
  • Check if the correct input source is selected on your monitor.
  • Try restarting the KVM switch and the connected computers.
  • Confirm that your HDMI cables support the desired resolution (e.g., 4K@60Hz).
• Keyboard/Mouse Not Responding:
  • Ensure the USB 3.0 cables from the computers to the KVM switch are properly connected.
  • Verify that the keyboard and mouse are connected to the dedicated USB 3.0 ports on the KVM switch.
  • Try connecting the keyboard and mouse directly to the computer to confirm they are functional.
  • Some specialized gaming keyboards/mice may require direct connection or specific drivers; try a standard keyboard/mouse first.
• Display Resolution/Refresh Rate Issues:
  • Ensure all connected devices (computers, monitor, HDMI cables) support the desired resolution and refresh rate (e.g., 4K@60Hz).
  • Adjust display settings on your computer to match the capabilities of your monitor and KVM switch.
• Switching Delay:
  • A slight delay during switching is normal as the system re-establishes connections. Excessive delays might indicate a cable issue; try replacing HDMI or USB cables.
