Dual HDMI KVM Matrix

The ESTONE OZK3-1 is a 2×2 HDMI KVM matrix that lets one keyboard and mouse control two computers across two monitors. It accepts HDMI and USB-C from each host and provides two HDMI outputs plus stereo audio. A USB 3.0 hub port is included for shared peripherals such as storage drives, printers or cameras. Switching is handled by front-panel buttons, keyboard hot-keys or the supplied IR remote.

Home office and streaming setups

This unit suits users who need simultaneous dual-monitor access to two systems — for example a work laptop and a gaming PC, or a desktop and a console — without unplugging cables. It supports Windows, macOS and Linux with no driver installation. Buyers who require more than two computer ports, DisplayPort native inputs, or higher than 4K 60 Hz refresh rates should consider other solutions.

HDMI 2.0b with HDCP 2.3

The single specification that determines compatibility is the HDMI 2.0b interface with HDCP 2.3 support. It carries 3840×2160 at 60 Hz and 1080p at up to 144 Hz in RGB 8:8:8 colour, plus 7.1-channel audio. If your sources or displays rely on a different HDMI version or lack HDCP 2.3, the matrix will not pass protected content or the full resolution and refresh-rate combination.

Questions about this item

How do I confirm the 4K 60Hz video is active after connecting both monitors?

The front panel LEDs show which computer is routed to each display; both monitors should show 3840x2160 at 60 Hz in the OS display settings.

Which cables are included and what must I provide for two computers and two monitors?

The box contains the matrix unit, two USB data cables, one USB power cable and an IR remote; you must supply four HDMI cables and two AAA batteries for the remote.

When should I use the HDMI inputs versus the USB-C inputs for my two computers?

Use HDMI for any source with native HDMI output; use USB-C only for laptops or devices that deliver video over USB-C alt-mode, as both input types feed the same 4K 60Hz matrix.
