Setup Instructions

Follow these steps to correctly set up your KVM switch:

1. Power Connection: Insert the provided DC12V power adapter into the KVM switch's DC/12V port.
2. Monitor Connection (Output): Connect your two DisplayPort monitors to the KVM switch's "DP OUT A" and "DP OUT B" ports using DisplayPort cables.
3. Computer Connection (Input): For each computer (PC1, PC2, PC3, PC4), connect two DisplayPort cables and one USB 3.0 cable to the corresponding input ports on the KVM switch. Ensure that DP IN A, DP IN B, and USB IN ports for each PC are correctly matched (e.g., DP IN1 A, DP IN1 B, and USB IN1 for PC1). Mixed insertion is not supported.
4. Peripheral Connection: Connect your keyboard, mouse, and any other USB 3.0 peripherals to the USB 3.0 ports on the front of the KVM switch.
5. Wired Remote (Optional): If desired, connect the wired remote controller to the "CONTROL" port on the KVM switch for external switching.

Important Setup Notes:

• Ensure each computer has two DisplayPort cables and one USB cable connected to the KVM switch. Incorrect connections are a common reason for video output issues.
• Before purchasing, confirm that your computer's graphics card supports direct connection of two DisplayPort monitors for proper dual-screen functionality.
• DisplayPort cables are not included with the KVM switch.

Operating Instructions

Switching Between Computers

The KVM switch offers two methods for switching between connected computers:

• Physical Button Switch: Press the corresponding PC button (PC1, PC2, PC3, or PC4) on the front panel of the KVM switch to select the desired computer. An LED indicator will illuminate to show the active computer.

• Wired Remote Controller: Use the included wired remote controller to switch between computers. Press the numbered buttons (1, 2, 3, or 4) to select the corresponding PC.

• LED Indicator: An LED light on the KVM switch indicates which computer is currently active.

Display Modes

The KVM switch supports various display modes, depending on your computer's graphics card capabilities:

• Extended Mode: Displays two different screens across your two monitors.
• Mirror Mode: Displays identical content on both monitors.
• Splicing Mode: Combines both monitors to act as a single, larger display. This mode requires your graphics card to support screen splicing functionality.

After connecting, you may need to set the screen output mode on your computer. For Windows, press Windows + P and select the desired output mode from the pop-up window.

Troubleshooting

• No Video Output or Only One Monitor Working: This is often due to incorrect cable connections. Ensure that for each computer, both DisplayPort cables (DP IN A and DP IN B) and the USB cable (USB IN) are correctly connected to their corresponding ports on the KVM switch.
• KVM Switch Unresponsive: If the KVM switch does not respond, try turning off the switch on the panel, waiting 2-3 seconds, and then turning it back on. This can reset the device.
• Resolution Issues (e.g., 8K@60Hz not achieved): To achieve maximum resolutions like 8K@60Hz, your computer's graphics card, monitors, and DisplayPort cables must all support that specific resolution and refresh rate. Verify the capabilities of all your connected devices.
• Display Arrangement Changes After Switching: The KVM switch does not feature EDID emulation. This means that when switching between computers, your operating system may detect the monitors as new devices, potentially rearranging window positions. You may need to manually adjust display settings after switching.
• USB Peripherals Not Reconnecting: If USB devices (keyboard/mouse) do not reconnect after switching, try power cycling the KVM switch or rebooting the affected computer.
