4-Port KM Switch with USB 3.2 Gen 1 Mouse Roaming Function

BEFORE YOU BUY!

If you intend to use mouse roam please use with only a single display (real or virtual) per input. Microsoft has disabled the ability to use more than one absolute co-ordinate pointing device in some Windows updates. 

This device is lower cost than a full KVM, but gives you the ability to switch inputs by key switch, shortcut key or based on absolute mouse co-ordinate (for fully HID-compliant USB mice only) 

This switch is pure hardware design, built-in 4 preset screen layout, no software or driver required, compatible with Windows and Mac system. 

• Allow 4 Computers to share USB peripherals ( USB HID x 3 + USB 3.2 Gen 1 x 2 ) 

• Mouse Roaming functionality makes perfect operation experience by simply moving the mouse cursor across screen border selecting the previous /next PC 

• Flexible Preset Screen Layout of 1 x 4, 2 x 2, 1 + 3 or 4 x 1. 

• Mouse Absolute Coordinate Technology enables seamless switch among PCs and adapts to all kinds of mouse sensitivity 

Optional:

• Support USB Audio: This version of the device supports audio functions with a basic built-in audio endpoint for each KM input on the switch. The rear I/O changes a bit and includes analog audio out. The basic version is only analog ports, USB audio is essentially an internal USB audio DAC which makes the cabling a little cleaner and is higher quality than analog audio.

Why Our KVM Switches Don’t Include an Ethernet Port

We often get asked why our KVM (Keyboard, Video, Mouse) switches don’t come with an Ethernet port. It’s a great question — and the answer has everything to do with keeping your network stable and your devices protected.

Our KVM switches are designed to cleanly switch control of your keyboard, video, and mouse — but networking is a different story. If we were to add an Ethernet port and try to switch it between devices, we’d essentially be reinventing something that already exists: a network switch.

Network switches are made to manage multiple devices on a shared network reliably and simultaneously. They handle traffic differently and are designed for constant connectivity — not for quick, manual switching like a KVM. Combining these two roles could lead to unnecessary complexity and reliability issues.

In short, we believe in using the right tool for the job. That’s why we leave networking to the dedicated Ethernet switches — and focus on building rock-solid KVMs that do their job well.

Important Usage Information: Corsair keyboards are currently unable to use KVM or KM hotkeys when plugged into HID ports.* 

Monitor Emulation

> This KVM does not support monitor emulation <

Monitor emulation makes sure the input has an exact copy of the display's EDID (Extended Display Identification Data) even when disconnected. Being that this KVM does not have monitor emulation, when switching between desktops, your monitor and KVM will re-handshake. AKA the windows will shuffle unless you have a software or hardware solution.

For your convenience, here are some compatible options that we know of with this KVM:

Windows

• Windows 11 - Settings > System > Display > Multiple Displays (drop down) and check the option labelled "Remember windows locations based on monitor connection" and uncheck "Minimize windows when a monitor is disconnected"

• Windows 10 - Persistent Windows https://github.com/kangyu-california/PersistentWindows

macOS

• macOS Ventura (and newer) - System Settings > Desktop \& Dock > Mission Control and uncheck the box next to "Automatically rearrange Spaces based on most recent use"

• macOS Monterey (and older) - System Preferences > Mission Control and uncheck the box next to "Automatically rearrange Spaces based on most recent use"

You can also use the terminal to change the setting.

To disable rearrangement:

defaults write com.apple.dock "mru-spaces" -bool "false" \&\& killall Dock"
