Familiarize yourself with the ports and indicators on the KVM switch.

3.1 Front Panel

The front panel features four USB 3.0 output ports for connecting peripherals such as keyboards, mice, printers, or USB drives. It also includes a 'KEY' button for manual switching between connected computers and LED indicators (1 and 2) to show which computer is currently active.

3.2 Rear Panel

The rear panel contains the input ports for two computers (PC1 and PC2), each requiring two DisplayPort inputs, one HDMI input, and one USB 3.0 input. It also has the output ports for three monitors (two DisplayPort and one HDMI) and the DC 5V power input.

4. Setup Instructions

Follow these steps to correctly set up your KVM switch:

1. Connect Monitors: Connect your three monitors to the KVM switch's output ports (DP OUT A, DP OUT B, HDMI OUT) using the provided DisplayPort 1.4 and HDMI 2.1 cables.
2. Connect Computers: For each computer (PC1 and PC2), connect the following cables from the computer's video outputs and USB 3.0 port to the corresponding input ports on the KVM switch:
   • Two DisplayPort cables (DP IN 1A/1B for PC1, DP IN 2A/2B for PC2)
   • One HDMI cable (HDMI IN 1 for PC1, HDMI IN 2 for PC2)
   • One USB 3.0 cable (USB3.0 IN 1 for PC1, USB3.0 IN 2 for PC2)

   Note: Ensure your computers have the necessary DP and HDMI ports. If not, a docking station or adapter may be required. Each computer must have its USB 3.0 cable connected to the KVM switch for keyboard and mouse functionality.
3. Connect USB Peripherals: Connect your keyboard, mouse, printer, or other USB 3.0 devices to the four USB OUT ports on the front panel of the KVM switch.
4. Connect Power: Plug the provided DC 5V power adapter into the KVM switch's power input port and then into a power outlet.
5. Connect Wired Controller: If desired, connect the wired desktop controller to the dedicated port on the KVM switch for convenient remote switching.

After all connections are made, power on your computers and monitors. The KVM switch is plug-and-play and generally does not require driver installation for Windows, Mac OS, or Linux systems.

5. Operating Instructions

5.1 Switching Between Computers

You can switch between the two connected computers using one of two methods:

• Panel Button: Press the 'KEY' button on the front panel of the KVM switch. The LED indicator will illuminate to show which computer is active.
• Wired Desktop Controller: Press the button on the wired desktop controller. This provides a convenient way to switch without reaching the KVM unit.

5.2 Display Modes

The KVM switch supports both extended and mirror display modes across your three monitors:

• Extended Mode: Each monitor displays a different part of your desktop, expanding your workspace.
• Mirror Mode: All monitors display the same content, duplicating your desktop.

These modes are configured through your computer's display settings (e.g., Windows Display Settings, macOS System Preferences).

5.3 Resolution Support

The KVM switch supports high resolutions and refresh rates:

• Up to 8K@60Hz
• Up to 4K@120Hz
• Backward compatible with 2K@144Hz, 1080P, 720P, etc.

To achieve 8K@60Hz or 4K@120Hz, ensure that your signal source (computer graphics card), monitors, and all connecting cables (DisplayPort 1.4 or HDMI 2.1) support these resolutions and refresh rates. The KVM switch automatically identifies resolutions when switching sources.

5.4 USB 3.0 Functionality

The four USB 3.0 output ports provide data transmission speeds of up to 5Gbps, which is significantly faster than USB 2.0. This allows for quick data transfer and responsive peripheral usage.

7. Troubleshooting

If you encounter issues, please refer to the following common problems and solutions:

• No Display or Incorrect Resolution:
  • Ensure all video cables (DP and HDMI) are securely connected between the computers, KVM switch, and monitors.
  • Verify that your computer's graphics card, monitors, and cables support the desired resolution and refresh rate (e.g., DP 1.4 or HDMI 2.1 for 8K/4K).
  • Try restarting the KVM switch by unplugging and re-plugging the power adapter.
  • Check your computer's display settings to ensure monitors are detected and configured correctly (extended or mirror mode).
• Keyboard/Mouse or USB Devices Not Recognized:
  • Confirm that the USB 3.0 cables are connected from each computer to the corresponding USB3.0 IN port on the KVM switch. This is crucial for USB peripheral functionality.
  • Ensure USB peripherals are connected to the USB OUT ports on the KVM switch's front panel.
  • Try connecting the USB device directly to the computer to confirm it is functional.
  • Restart the KVM switch and the connected computers.
• Switching Delays:
  • A brief delay during switching is normal as the KVM re-establishes connections.
  • Ensure all cables are of good quality and properly seated.
• Only Two Monitors Displaying:
  • Double-check all three video connections from the KVM switch to your monitors.
  • Verify that your computer's graphics card supports output to three independent displays simultaneously.
