4. Setup Instructions
Follow these steps to connect your KVM switch and computers:
- Power Off Devices: Ensure all computers and monitors are powered off before making any connections.
- Connect Monitors: Connect your two monitors to the KVM switch's "HD OUT B" (HDMI) and "DP OUT A" (DisplayPort) ports.
- Connect Computers (PC 1, PC 2, PC 3):
- For each PC, connect its HDMI output to the corresponding "HD INPUT B" port on the KVM (e.g., PC1 HDMI to HD INPUT B1).
- For each PC, connect its DisplayPort output to the corresponding "DP INPUT A" port on the KVM (e.g., PC1 DP to DP INPUT A1).
- For each PC, connect one of the included USB 3.0 cables from the PC's USB 3.0 port to the corresponding "USB 3.0" input port on the KVM (e.g., PC1 USB to USB 3.0 input for PC1). This connection is crucial for keyboard, mouse, and other USB peripheral sharing.
- Connect Peripherals: Connect your keyboard, mouse, and other USB 3.0 devices (e.g., U disk, printer) to the four "USB 3.0" ports on the front panel of the KVM switch.
- Connect Wired Remote: If desired, connect the wired remote controller to the "Wired Remote" port on the KVM switch.
- Power On: Connect the DC 12V power adapter to the KVM switch and then plug it into a power outlet. Turn on the KVM switch using the ON/OFF switch.
- Power On Computers and Monitors: Power on your monitors and then your computers.
Important Cable Note: Please use DP1.4 and HDMI2.1 cables. Keep cable lengths as short as possible to ensure a stable signal, especially for high resolutions.

- Environment: Keep the device in a cool, dry place, away from direct sunlight, heat sources, and moisture.
- Handling: Avoid dropping or subjecting the device to strong impacts.
- Power: Always use the provided DC 12V power adapter. Disconnect power when the device is not in use for extended periods.
7. Troubleshooting
If you encounter issues with your KVM switch, please refer to the following common solutions:
- No Display on Monitors:
- Ensure all HDMI and DisplayPort cables are securely connected between the KVM, monitors, and PCs.
- Verify that the KVM switch is powered on and the correct PC is selected.
- Check if your monitors are set to the correct input source (HDMI/DP).
- Confirm that your PCs have both HDMI and DP outputs and that they belong to the same graphics card (especially for discrete GPUs).
- Try using shorter, high-quality HDMI 2.1 and DP 1.4 cables.
- USB Devices (Keyboard/Mouse) Not Working:
- Ensure the USB 3.0 input cables are correctly connected from each PC to the KVM switch. If these are not connected or are poorly connected, USB output devices will not be recognized.
- Try connecting the USB devices directly to the PC to confirm they are functional.
- Restart the KVM switch and the connected PCs.
- Resolution or Refresh Rate Issues:
- Verify that your monitors and graphics cards support the desired resolution and refresh rate.
- Ensure you are using high-quality HDMI 2.1 and DP 1.4 cables, as older or lower-quality cables may not support 8K or high refresh rates.
- Check your PC's display settings to ensure the correct resolution and refresh rate are selected.
- Switching Delays:
- Ensure all cables are securely connected.
- Some monitors may take a few seconds to detect the new signal after switching. This is normal behavior.
