4K@144Hz DisplayPort KVM Switch Dual Monitor for 2 Computers - Fast

In this review of the 4K@144Hz DisplayPort KVM Switch, the bottom line is clear: this unit is aimed at power users who need to share two monitors and multiple USB devices between two desktop computers with minimal fuss. It stands out for supporting up to 4K@144Hz and offering four front USB 3.0 ports, making it a strong choice for creative professionals, gamers, and multitaskers who require high refresh rates and fast peripheral access. Setup requires attention to DisplayPort wiring, but once configured the switch delivers reliable, low-latency operation.

Key Features

• Dual DisplayPort support: Lets two PCs share two monitors with full extended or copy mode when each PC has two DP outputs.
• High refresh 4K: Supports up to 3840x2160 at 144Hz for crisp, fluid video where the GPU, monitors, and cables all allow.
• USB 3.0 front ports: Four USB 3.0 ports provide up to 5Gbps for fast external drives and responsive USB devices while remaining backward compatible with USB 2.0/1.1.
• Physical desktop controller: A dedicated controller and front button make switching immediate and clear with LED indicators for the active PC.
• External power design: Ships with a 12V/1A adapter so attached USB devices get stable power through the switch for consistent operation.

Who It's For

This KVM is best for users who run two full-featured desktops - for example a work PC and a gaming or personal rig - and who can meet the wiring requirements of two DP cables per computer and DP inputs on each monitor. It suits video editors, competitive gamers, and professionals who need high refresh rates and multiple USB peripherals available to both machines.

It is not the right choice for casual single-display setups, laptop-only users without dual DP outputs, or anyone who plans to rely on DP/HDMI conversion adapters, as those are not supported. Mac users should be cautious because broad compatibility with Mac devices is not recommended by the manufacturer.

Pros & Cons

Pros

• Supports true 4K@144Hz performance when paired with compatible GPUs, monitors, and DP1.4 cables.
• Fast, reliable switching via the included desktop controller and front button with clear LED feedback.
• Four USB 3.0 ports give high-speed connectivity and backward compatibility for legacy devices.

Cons

• Requires two DP cables per computer and no DP/HDMI adapters are supported, which complicates setups that mix connector types.
