KVM Switch Dual Network Cable Connection

A dual-network or dual-video KVM setup requires connecting two video cables and one USB cable per computer to the KVM switch to enable dual-monitor support and seamless switching.

Understanding Dual Connections

For a dual-monitor KVM switch, each computer must have two video outputs (HDMI, DisplayPort, or DVI) connected to the KVM switch. This allows the KVM to extend the desktop across two monitors for each system. Additionally, a USB connection is required for keyboard and mouse control. If your computer lacks sufficient video ports, you may need a PCI graphics card with dual outputs or a DMS-59 adapter to provide the necessary connections .

Cable Requirements

• Video Cables: Each computer requires two video cables corresponding to the KVM switch's input ports. For HDMI, use Premium High-Speed HDMI cables for 4K at 60Hz or Ultra High-Speed HDMI cables for 4K at 120Hz or 8K . For DisplayPort, ensure the cables support the desired resolution and refresh rate.
• USB Cables: Connect each computer's USB port to the KVM switch to enable keyboard and mouse control. USB 3.0 cables are recommended for high-speed peripherals .
• Adapters: If your computer's video output type differs from the KVM input, use appropriate adapters (e.g., USB-C to HDMI or DisplayPort) to ensure compatibility .

Step-by-Step Setup

1. Identify Ports: Check the KVM switch for dual video input ports per channel and USB input ports.
2. Connect Computers:
   • Connect two video cables from each computer to the KVM switch.
   • Connect the USB cable from each computer to the KVM switch.
3. Connect Monitors: Attach your dual monitors to the KVM switch's console output ports.
4. Power On and Test: Turn on the KVM switch and computers. Switch between computers to verify that both monitors display correctly and that keyboard/mouse control works.
5. Optional Network Integration: If using a KVM-over-IP switch, connect the Ethernet port to your network for remote access. CPU ports use RJ45 connections for video and USB signal transmission, not standard 10/100 Base-T networking .

Tips for Smooth Operation

• Ensure all cables are high-quality and compatible with your resolution and refresh rate requirements.
• Label cables and ports to avoid confusion when switching between multiple computers.
• If using laptops with USB-C ports, check whether MST mode is required for dual-monitor support .
• Verify that each computer's graphics card supports dual monitors before connecting to the KVM switch. By following these steps and using the correct cables, a dual-network or dual-video KVM switch setup allows efficient control of multiple computers with extended desktop support across two monitors.
