Dual-monitor KVM for two computers

This 2x2 HDMI KVM switch lets a single keyboard, mouse and dual-display setup control two computers or laptops. It supports extended or mirrored desktop modes across both monitors without cable swapping or tethering software. The unit is driver-free on Windows, macOS, Linux and UNIX systems.

HDMI 2.0 bandwidth and USB 3.0 limits

Video passes through HDMI 2.0 at 3840 x 2160 resolution and 60 Hz refresh. The switch provides two USB 2.0 ports and two USB 3.0 ports for peripherals, while dedicated keyboard and mouse ports enable hot-key commands. Audio extracts via a 3.5 mm jack. No external power supply is required.

Push-button, hot-key and IR switching

Three switching methods are built in: front-panel push buttons, keyboard hot keys and an included IR remote. Hot-key switching only works when the keyboard and mouse are plugged into the marked K/M ports. Each computer must supply two HDMI outputs and a USB connection; systems with a single video port need an active converter. The remote ships without a AAA battery.

Questions about this item

Should I pick the version with 2 USB 2.0 ports and 2 USB 3.0 ports or a different capacity?

This model provides exactly two USB 2.0 ports for keyboard and mouse plus two USB 3.0 ports for other devices; no other port-count versions are listed.

What does the 4K 60Hz rating mean when I connect two monitors to my PCs?

Each monitor can run at 3840 x 2160 resolution at 60 Hz over HDMI 2.0, giving full UHD quality on both screens simultaneously.

How does the HDMI 2.0 interface limit my setup in practice?

HDMI 2.0 caps video at 3840 x 2160 at 60 Hz and carries audio to the 3.5 mm jack; higher refresh rates or resolutions are not supported.
