3. Setup Instructions
Proper connection of all cables is essential for optimal performance. Each PC requires specific video and USB connections to the KVM switch.
3.1. Cable Requirements per PC
For each PC (up to 3 PCs), you will need to connect the following cables to the KVM switch:
- 1x HDMI cable (for one monitor output)
- 2x DisplayPort cables (for two additional monitor outputs)
- 1x USB 3.0 cable (for keyboard, mouse, and other USB peripherals)
Note: If your PC does not have the required 1 HDMI + 2 DisplayPort outputs, adapters (e.g., DP to HDMI, Mini DP to DP, USB-C to DP/HDMI) or a USB-C docking station may be necessary. Ensure all cables are of high quality and support the desired resolution (e.g., 8K DP1.4 and HDMI 2.1 cables for 8K resolution).
3.2. Connecting PCs to the KVM Switch
- Connect the 1 HDMI, 2 DisplayPort, and 1 USB 3.0 cables from PC1 to the corresponding 'INPUT 1' ports on the KVM Switch.
- Repeat step 1 for PC2, connecting to the 'INPUT 2' ports.
- Repeat step 1 for PC3, connecting to the 'INPUT 3' ports.
3.3. Connecting Monitors to the KVM Switch
- Connect your first monitor to 'OUT A' (HDMI).
- Connect your second monitor to 'OUT B' (DisplayPort).
- Connect your third monitor to 'OUT C' (DisplayPort).
3.4. Connecting Peripherals and Power
- Connect your keyboard, mouse, printer, USB flash drive, or other USB 3.0 devices to the 4 USB 3.0 ports on the front of the KVM Switch.
- Connect the wired remote control to the dedicated port on the front panel.
- Connect the 12V DC power adapter to the KVM Switch and plug it into a power outlet. This is recommended for stable operation, especially when using high-power USB devices like hard drives or webcams.

5. Maintenance
To ensure the longevity and optimal performance of your KVM Switch:
- Keep the device in a cool, dry place away from direct sunlight and excessive heat.
- Clean the exterior with a soft, dry cloth. Avoid using liquid cleaners or abrasive materials.
- Ensure all cable connections are secure to prevent signal loss or intermittent issues.
- Avoid placing heavy objects on the KVM Switch.
6. Troubleshooting
6.1. No Display or Incorrect Resolution
- Check Cables: Ensure all HDMI and DisplayPort cables are securely connected to both the KVM Switch and your monitors/PCs. Verify that you are using high-quality cables that support the desired resolution.
- Power Supply: Confirm the 12V DC power adapter is connected and providing power to the KVM Switch. While the KVM may function without it for low-power USB devices, it is crucial for stable video output and high-power USB peripherals.
- PC Output Settings: Verify your PC's display settings are configured for extended or mirrored displays as desired. Use the "Windows + P" shortcut on Windows.
- Graphics Card Compatibility: The final resolution is subject to your graphics cards, monitors, cables, and adapters. Ensure your hardware supports the desired 8K or 4K resolutions.
- Driver Updates: For certain operating systems, especially macOS with DisplayLink docking stations, ensure you have the latest DisplayLink drivers installed. Older drivers or systems might only support a limited number of external monitors (e.g., two instead of three extended displays).
6.2. Keyboard/Mouse Not Responding
- USB Cable Connection: Ensure the USB 3.0 cables from each PC to the KVM Switch are properly connected.
- Power Adapter: If using high-power USB devices, ensure the 12V DC power adapter is connected to the KVM Switch.
- Peripheral Compatibility: While generally compatible, some specialized keyboards or mice might have unique driver requirements. Try a standard keyboard/mouse to isolate the issue.
6.3. Switching Delays
A brief delay during switching is normal as the KVM re-establishes connections. If delays are excessive, check cable quality and ensure the power adapter is connected.
