4K144Hz HDMI + 2 DisplayPort KVM Switch 3 Monitors 4 Computers

In this review the 4K144Hz HDMI + 2 DisplayPort KVM Switch is judged as a practical, high-performance option for users who need to share three monitors and multiple USB devices across four computers. The single biggest reason to buy is its combination of high-resolution video support and four USB 3.0 ports, which together make multi-computer desktop control smooth and efficient for power users. Setup requires each PC to have two DP ports and one HDMI port for three-monitor support, but once connected the switch simplifies workflows and keeps a cluttered desk under control.

Key Features

• 4-computer KVM: Lets four PCs or laptops share three displays and four USB peripherals for centralized management and a tidier workspace.
• High-resolution video: Supports up to 8K@60Hz and is backward compatible with 4K@144Hz, enabling crisp, high-frame-rate output for work or gaming.
• USB 3.0 ports: Four USB 3.0 ports provide up to 5Gbps transfers and hot-swapping for fast, reliable peripheral connectivity.
• Wireless infrared control: Panel buttons and an infrared receiver allow convenient switching from the desktop without moving the main unit.
• Broad compatibility: Works with Windows, MacOS and Linux systems and includes a 12V power adapter for stable operation.

Who It's For

This KVM switch is aimed at professionals, content creators and advanced hobbyists who run multiple workstations and need to share three monitors along with USB peripherals. It is especially useful for anyone who benefits from high refresh rate 4K output and fast USB 3.0 transfers while switching control between four computers.

It is not ideal for users whose graphics cards lack the required ports (each computer must have two DP ports and one HDMI port to use three monitors), or for those who only need a simple two-computer KVM. Casual single-computer users will find the unit oversized for basic needs.

Pros & Cons

Pros

• Supports triple-monitor setups across four computers, which greatly reduces desktop clutter and improves workflow.
• Video support up to 8K@60Hz and backward compatibility with 4K@144Hz produces excellent image quality and smooth motion.
• Four USB 3.0 ports with hot-swap support deliver fast peripheral performance and reliable data transfers.
• Infrared remote and front-panel buttons make switching convenient without reconfiguring cables.

Cons

• Requires specific graphics outputs per computer (2 DP + 1 HDMI) to drive three monitors, which may limit compatibility with some systems.
• Setup is more involved than a simple KVM because of multiple video and USB 3.0 cable connections.
