Four-Computer Control

This KVM switch lets you operate four computers from a single keyboard, mouse and monitor. It suits professionals who manage multiple workstations or home users who share peripherals across desktops and laptops. Switching between systems is instant, keeping workflows uninterrupted.

Check HDMI and USB Ports

Verify that each computer provides an HDMI video output and at least one USB port for the keyboard and mouse connection. The switch supports HDMI 2.0 and HDCP 2.2, so confirm your sources and display can handle those standards. Ensure the monitor accepts resolutions up to 4K@60Hz for full capability.

Three USB 3.0 Ports Add Peripheral Sharing

The unit includes three USB 3.0 ports running at 5Gbps, letting all four computers share a printer, storage drive or other USB device without extra hubs. An optional 5V power input stabilises operation when high-power peripherals are attached. Backward compatibility with USB 2.0 covers older accessories.

Questions about this item

What cables come in the box and which ones do I need to buy separately?

The package includes the KVM switch and a 5V power adapter. You must supply four HDMI cables to connect each computer and three USB cables to link the computers to the switch's USB 3.0 ports.

How do I choose between the available versions or capacities for this switch?

This model is a single 4-port HDMI KVM switch supporting 4K at 60Hz with three USB 3.0 ports; there are no alternative port counts or bandwidth tiers to select.

What does the 4K 60Hz rating mean when I connect it to my monitor and computers?

It means the switch passes video up to 4K resolution at 60 frames per second via HDMI 2.0 with HDCP 2.2, and will downscale automatically to 1080p, 720p or 480p if a connected display only supports those modes.
