StarTech P4A20132-KM-SWITCH 4 Port Keyboard & Mouse Switch

Overview

The StarTech P4A20132-KM-SWITCH is a professional-grade 4-port USB KM (Keyboard and Mouse) switch designed for environments where a user needs to control four independent computers, each with its own dedicated display. This switch is a powerful tool for command centers, trading floors, and high-productivity workstations, allowing a single set of peripherals to manage four systems simultaneously without the bulk of a traditional KVM video switch.

The defining feature of this unit is Mouse Roaming (also known as boundless switching). This technology allows you to switch control between connected computers simply by moving your mouse cursor across the edges of your monitors. It creates a seamless “virtual desktop” experience across four distinct physical machines. For setups with varying physical arrangements, the switch offers six preset monitor layout configurations to ensure the mouse roams logically between screens.

In addition to KM sharing, the P4A20132-KM-SWITCH serves as a high-speed peripheral hub. It features two USB 3.2 Gen 1 (5Gbps) ports for data-intensive devices and three USB 2.0 ports for additional HIDs. It also supports independent audio switching, allowing you to listen to audio from one computer while working on another.
