Overview

If you juggle multiple PCs on one desk, constantly swapping monitors, keyboards, and mice can get tedious. The Buerlaseul KVM-4PCs is a 4-input, 1-output KVM switch designed to let you share a single HDMI display and four USB devices across up to four computers. Switching is as simple as pressing a button on the unit or using the included remote control.
This switch supports resolutions up to 4K@60Hz and includes four USB 3.0 ports for high-speed data transfer. It requires no driver installation—just connect an HDMI cable and a USB cable from each PC, and you're ready to go. It works with Windows, macOS, and Linux, making it a flexible option for mixed-OS environments.

Connectivity & Compatibility

Setup is straightforward: connect one HDMI cable and one USB cable from each PC to the switch, then connect your monitor to the HDMI output and your peripherals to the USB 3.0 ports. The USB 3.0 interface supports data transfer speeds up to 5Gbps, so moving files to an external SSD or USB flash drive feels snappy.
The switch is compatible with Windows, macOS, and Linux, and requires no drivers. However, it does not support docking stations or VGA/DVI-to-HDMI converters, so those setups won't work. Also, keyboard shortcut (hotkey) switching is not supported—you'll need to use the physical buttons or the remote.
For 4K@60Hz output, your PC, cables, and monitor must all support 4K@60Hz. The manufacturer recommends keeping cable lengths under 3 meters to avoid signal instability. For reliable operation, it's advised to power the switch using the included USB power cable.

Best Use Cases

  • Home workers who switch between a work laptop and a personal desktop: share one monitor, keyboard, and mouse to keep the desk tidy. The remote control is handy for switching from a distance.
  • Creators or engineers running multiple PCs on a single display: 4K@60Hz support keeps high-resolution work sharp. Those accustomed to hotkey switching may find the lack of it limiting.
  • Budget-conscious students or users who want to share peripherals across several machines: avoid buying duplicate keyboards and mice, saving money. Not suitable for those relying on docking stations.
