- Connect PC1: Connect PC1 to the KVM switch using one USB A-B cable (from PC1's USB port to 'USB 1' on the KVM) and two HDMI cables (from PC1's HDMI outputs to 'HD IN 1A' and 'HD IN 1B' on the KVM).
- Connect PC2: Connect PC2 to the KVM switch using the second USB A-B cable (from PC2's USB port to 'USB 2' on the KVM) and two HDMI cables (from PC2's HDMI outputs to 'HD IN 2A' and 'HD IN 2B' on the KVM).
- Connect Keyboard and Mouse: Connect your keyboard and mouse to the dedicated USB 2.0 ports on the front of the KVM switch.
- Connect Monitors: Connect your two monitors to the 'HD OUT A' and 'HD OUT B' ports on the KVM switch using HDMI cables.
- Power On: Ensure all connections are secure, then power on your computers and monitors.
Important Note: For optimal performance, especially when using 4K@60Hz resolution, ensure all HDMI cables used are HDMI 2.0 compliant. Using HDMI 1.4 cables may result in lower resolutions or prevent the switch from functioning correctly.

Display Modes
Your monitors can be configured in either Extended Display Mode or Mirror (Copy) Display Mode through your computer's display settings. The KVM switch supports both:
- Extended Mode: Outputs two different screens, allowing for an expanded desktop workspace.
- Mirror Mode: Outputs two identical screens, duplicating the display content.
Adaptive EDID Functionality
The KVM switch features adaptive EDID (Extended Display Identification Data). This ensures that when you switch from one computer to another and then switch back, your windows and desktop icons will remain in their original positions, preventing screen rearrangement and improving workflow efficiency.
6. Maintenance
To ensure the longevity and optimal performance of your KVM switch, please observe the following 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. Do not block the ventilation slots on the device, as this can lead to overheating. The built-in heat sink is designed to dissipate heat, but proper airflow is still important.
- Storage: When not in use for extended periods, store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Cable Management: Keep cables neatly organized and avoid sharp bends or excessive tension, which can damage the cables or ports.
7. Troubleshooting
If you encounter issues while using your KVM switch, please refer to the following common problems and solutions:
- No Display or Incorrect Resolution:
- Ensure all HDMI cables are securely connected to both the KVM switch and your computers/monitors.
- Verify that you are using HDMI 2.0 compliant cables, especially for 4K@60Hz resolution. HDMI 1.4 cables may not support this resolution and could cause display issues or prevent the switch from working.
- Check your computer's display settings to ensure the correct resolution and display mode (extended/mirror) are selected.
- Try restarting the KVM switch by disconnecting and reconnecting the power cable.
- Keyboard/Mouse Not Responding:
- Ensure the USB A-B cables are securely connected from your computers to the KVM switch.
- Verify that your keyboard and mouse are connected to the designated USB 2.0 ports on the KVM switch.
- Try connecting the keyboard and mouse directly to the computer to confirm they are functional.
- If using high-power USB devices, ensure the external 5V power supply is connected to the KVM switch.
- Switching Issues:
- Ensure the KVM switch is powered on and the indicator lights are functioning correctly.
- Press the 'SWITCH' button firmly.
If you continue to experience issues after attempting these troubleshooting steps, please contact GREATHTEK customer support for assistance.
