Setup Instructions

Follow these steps to connect your KVM switch:

General Connection Requirements:

Each PC requires two HDMI cables, one DisplayPort cable, and one USB cable to connect to the KVM switch for triple monitor display.
If your PC lacks the necessary HDMI or DisplayPort outputs, adapters (e.g., USB-C to DP/HDMI, DP to HDMI) or a USB-C docking station may be required. Ensure these adapters are compatible and support the desired resolution and refresh rate.

Operating Instructions

Switching Between Computers:

You can switch between connected computers using two methods:

Button Switch: Press the corresponding PC button (PC1, PC2, PC3, or PC4) on the front panel of the KVM switch. The LED indicator will show the active computer.
Wired Remote: Use the included wired remote control to switch between computers with a single press.

Image illustrating the two switching methods: pressing the PC buttons on the KVM switch or using the wired remote control. — Figure 6: Switching Methods (Button and Wired Remote)

Display Modes (Extended and Mirrored):

The KVM switch supports both extended and mirrored display modes across your three monitors. You can configure these modes through your operating system's display settings.

Extended Mode: Outputs three different screens, allowing you to extend your desktop across all three monitors.
Mirror Mode: Outputs three identical screens, duplicating your display across all three monitors.

Image showing two output modes: Mirror mode where all three monitors display the same content, and Extended mode where the desktop is spread across three different screens. — Figure 7: Mirror Mode vs. Extended Mode

EDID Simulation:

The KVM switch features EDID (Extended Display Identification Data) simulation. This technology stores the resolution and refresh rate of your displays. When you switch between computers, the KVM switch simulates the EDID, preventing your windows from rearranging or resizing, which is a common issue with KVMs without this feature.

Configuring Display Settings:

Windows OS: Use the shortcut key "WIN+P" and then select "Extend" or "Duplicate" (mirror) as needed.
Mac OS: Go to "Apple Icon" > "System Preferences" > "Display" > "Arrange", then check "Mirror Display" for mirrored mode or uncheck for extended mode.

Maintenance

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

Cleaning: Use a soft, dry cloth to wipe the exterior of the KVM switch. Avoid using liquid cleaners or abrasive materials, as they may damage the surface or internal components.
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.
Power Off: If the KVM switch will not be used for an extended period, it is recommended to power it off and disconnect the power adapter.

Troubleshooting

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

No Display or Incorrect Resolution:

Check Cables: Ensure all HDMI, DisplayPort, and USB cables are securely connected to both the KVM switch and your computers/monitors. Loose connections are a common cause of display issues.
Cable Quality: For 4K@60Hz resolution, ensure you are using high-quality HDMI 2.0 and DisplayPort 1.2 cables. Lower quality or older cables may not support the required bandwidth.
Adapter Compatibility: If using adapters (e.g., USB-C to DP/HDMI), verify they support 4K@60Hz and are functioning correctly.
Power Supply: Confirm the KVM switch is properly powered by the included DC 12V adapter.
Monitor Settings: Check your monitor's input source settings to ensure they are set to the correct input (HDMI or DisplayPort).
PC Display Settings: Verify your computer's display settings (as described in the Operating section) are configured for extended or mirrored mode as desired.

Keyboard/Mouse or USB Peripherals Not Working:

USB Connections: Ensure the USB 3.0 cables from each PC are connected to the corresponding USB 3.0 INPUT ports on the KVM switch. Also, ensure your peripherals are connected to the USB 3.0 OUT ports.
Peripheral Power: Some high-power USB devices may require external power. Ensure such devices are adequately powered.
Switching: Confirm that the KVM switch is set to the correct PC input.

Window Rearrangement After Switching:

The KVM switch is designed with EDID simulation to prevent this. If you experience this issue, ensure all connections are stable and the KVM switch is receiving adequate power. Restarting the KVM switch and connected computers may resolve temporary glitches.
