Operating Instructions

Switching Between Computers

Use the wired desktop controller or the "Switch" button on the KVM unit to toggle between PC1 and PC2. A single press will switch the active computer.

This image demonstrates the use of the wired desktop controller to switch between computers, showing it placed conveniently on the desk.

Display Modes

The KVM switch supports various display configurations:

• Triple 4K@60Hz Display: Connect three monitors for extended display at 4K resolution and 60Hz refresh rate.
• Dual 4K@120Hz Display: For smoother performance, connect two DisplayPort monitors to achieve 4K resolution at 120Hz. This requires your laptop to support Thunderbolt 4.

This image illustrates different monitor setups, including a quad display for a Windows laptop and a triple display for a desktop, demonstrating the KVM's multi-monitor capabilities.

This diagram shows two different dual monitor configurations: one with a DisplayPort and an HDMI monitor (4K@120Hz DP, 4K@60Hz HDMI), and another with two DisplayPort monitors (both 4K@120Hz), highlighting the need for Thunderbolt 4 for higher refresh rates.

Power Delivery and Charging

The KVM switch provides 100W Power Delivery (PD) pass-through charging for your connected laptop via the USB-C host port. Additionally, a dedicated 65W USB-C port is available for charging other devices like smartphones or tablets. The included 120W power adapter ensures stable power for all connected devices.

Data Transfer

Utilize the USB 3.0 and USB-C data ports for high-speed data transfer up to 5Gbps. The integrated Micro SD/SD card slots allow for convenient access to memory cards.

This image highlights the high-speed data transfer capabilities of the KVM switch, showing a USB 3.0 flash drive and SD/Micro SD cards connected, with a comparison of 5Gbps (USB 3.0) vs 480Mbps (USB 2.0).

Compatibility

The USB-C Host Port requires your laptop's USB-C port to support DisplayPort Alternate Mode (DP Alt Mode) and data transmission, or be a Thunderbolt 3/4/5 port.

Compatible Laptop Models (Partial List)

This image provides a list of partially compatible laptop models from various brands (HP, Dell, Lenovo, Acer, Asus, Microsoft, MSI, Samsung, Alienware) that support the necessary USB-C features for this KVM switch.

Display Configurations for Operating Systems

Windows (Extended Display - MST Mode)

For Windows operating systems, the KVM switch supports extended display (MST mode), allowing each monitor to show different content.

Windows & macOS (Mirror Display - SST Mode)

For both Windows and macOS, the KVM switch supports mirror display (SST mode), where all connected monitors display the same content.

Note: macOS does not support extended display (MST) mode through this KVM switch.

This image visually explains the difference between extended display (Windows only) and mirror display (Windows & macOS) modes when using the KVM switch with multiple monitors.

Troubleshooting

USB Not Working

• Confirm the USB 3.0 cable is properly connected between the computer and the KVM.
• Verify that the computer's USB port is functioning correctly.
• Ensure the latest USB driver is installed on the computer.

Display Has No Image

• Confirm that the switch and KVM video ports match the correct inputs/outputs.
• Verify that PC to KVM input cables are connected correctly (e.g., Input A to OUT-A display, Input B to OUT-B display).
• Use high-quality video cables (e.g., 3.3ft). Conversion cables are not supported.
• If an adapter is required, use an active adapter.

General Display Issues

• If experiencing green fuzz or artifacts at higher refresh rates, ensure both devices are outputting at a compatible refresh rate (e.g., 60Hz for office work).
• If monitors sporadically show display or not all three monitors work, re-plug the laptop or check all cable connections.
• Ensure your laptop's USB-C port supports Thunderbolt 4 for Dual 4K@120Hz display.
