This is the Rybozen Smart Dual HDMI KVM Switch — lets you share one keyboard, mouse, and two monitors between two computers. 4K at 30Hz resolution support. Three ways to switch between computers: front panel button, keyboard hotkey, or double-click your mouse's middle button.

I bought this for a home office A/V project that never got off the ground. It's never been opened — the switch is still sealed in its original plastic wrap inside the box. Everything is included: the KVM switch, quad HDMI integrated cable, two HDMI cables, user manual, and warranty card.

If you're running two machines — say a work laptop and a personal desktop — and you're tired of swapping cables or reaching for a second keyboard, this is the fix. One set of peripherals, two computers, instant switching. Plug and play on Windows and macOS, no drivers needed.

Features USB 2.0 hub ports for sharing peripherals like a printer or scanner across both machines, plus audio output for headphones or speakers.

Brand new, never taken out of plastic, from a smoke-free home.
