StarTech.com 4-Port KM Switch w/ Mouse Switching, USB 3.0 Keyboard/Mouse Switcher for 4 Computers, 3.5mm and USB Audio, TAA Compliant

This Keyboard and Mouse (KM) Switch enables switching a single keyboard and mouse between multiple computers using mouse roaming, allowing users to seamlessly move the cursor across multiple screens (i.e., one monitor per computer).

Mouse Switching

Switch between computers by moving the mouse between monitors, enabling uninterrupted workflow and increased efficiency. Hotkey and push-button switching are universally compatible. Mouse Switching is supported by most major desktop operating systems, including Windows, macOS, and Linux.

Preset Monitor Layouts

To accommodate various physical monitor setups, there are four preset display configurations available. This allows for smooth mouse movement across host monitors.

Thoughtful Design

Hotkeys enable listening to audio from one computer while controlling another. USB audio and 3.5mm pass-through are available, and LEDs provide visual port selection status, while an audible buzzer confirms hotkey selection.

Note: On computers with multiple monitors connected with Mouse Switching/Roaming enabled, mouse/keyboard operation is limited to the primary display
