Displayport KVM Switch 2 Monitors 2 Computers - Dual 4K@144Hz Control

In this review we look at the Displayport KVM Switch 2 Monitors 2 Computers to see who benefits most from a dual-display DisplayPort KVM. The bottom line: this unit is aimed at users who need to control two systems with two monitors and multiple USB devices while preserving high refresh and resolution; its biggest selling point is support for up to 4K@144Hz on compatible hardware. Setup is relatively straightforward if each computer has two DP outputs and the right cables, and the included desktop controller makes switching convenient for daily workflows.

Key Features

• Dual DisplayPort Outputs: Lets you share two monitors between two computers, maintaining separate extended or copy display modes as required.
• High Refresh 4K Support: Supports up to 3840x2160 at 144Hz for crisp motion if your GPU and monitors can deliver that bandwidth.
• USB 3.0 Hub: Four USB 3.0 ports provide faster data rates and can recognize keyboards, mice and other peripherals for a unified desktop.
• Two Switching Options: Provides both a front-panel button and an external wired desktop controller so you can switch without reaching the unit.
• External Power Design: Includes a 12V DC adapter to keep connected USB devices stable during operation.
• Package and Support: Ships with USB-A 3.0 cables, a desktop controller, a DC12V adapter and a one-year return or replacement policy.

Who It's For

This KVM is best for professionals, content creators and power users who run two desktop systems and need to share a pair of monitors and several USB devices without swapping cables. It fits setups where each computer can provide two DisplayPort outputs and the graphics hardware supports multi-monitor output and high refresh rates.

It is not ideal for casual single-monitor users or laptops that lack dual DP outputs, and buyers who require guaranteed compatibility with every combination of 4K at 144Hz monitors should test their specific GPU and cable setup first, since final performance depends on the graphics card, monitors and cables.

Pros & Cons

Pros

• Supports high bandwidth video up to 4K@144Hz for responsive, detailed displays when hardware allows.
• Built-in USB 3.0 hub gives faster peripheral throughput and convenient device sharing.
• External wired controller and front panel button make switching quick and ergonomic.
• Includes power adapter and required USB cables in the box for immediate use.

Cons

• Requires two DP ports per computer and compatible GPUs, which limits use with many laptops or single-output systems.
• Some users report mixed compatibility and occasional flickering or refresh limitations depending on monitors, cables and GPUs.

Our Verdict

The Displayport KVM Switch is a practical choice for users who need to control two computers with dual monitors and want high refresh capability without constantly swapping cables. It delivers strong value when paired with compatible GPUs, proper DisplayPort cables and monitors, though buyers should be aware of potential compatibility limits and test their monitor and GPU combination if aiming for sustained 4K@144Hz performance.

Frequently Asked Questions

Do both computers need two DisplayPort outputs?
Yes. Each computer must have two DP outputs connected to the DP1 and DP2 inputs on the switch to enable dual-monitor operation.

Are DP cables included?
No. The package includes USB-A 3.0 cables but DP cables are not included, so quality DP cables are required to reach high resolutions.

Will it always run 4K at 144Hz?
Not always; the final resolution and refresh depend on the graphics card, monitors, cable quality and any adapters used, so performance can vary by system.
