2×2 HDMI KVM Matrix Switch

This LUOM OZK3-1 matrix switch lets two computers share one keyboard, one mouse and two HDMI monitors. It is built for users who need simultaneous dual-screen access to both systems without moving between workstations. Office workers, streamers and home-lab builders can toggle between a laptop and a desktop or a game console with a single button press or hotkey. The unit supports Windows XP through Windows 10 and macOS for broad compatibility.

Bundled Cables and IR Remote

The package supplies two USB data cables and one USB power cable so both host connections are ready immediately. An IR remote control adds desk-distance switching without reaching for the front panel, though it ships without the required AAA battery. A printed user manual completes the kit for quick first-time setup. No additional software or drivers are included in the box.

HDMI 2.0b with HDCP 2.3 at 4K 60 Hz

The single specification that determines fit is the HDMI 2.0b interface with HDCP 2.3, delivering 3840×2160 at 60 Hz and 1080p at up to 144 Hz with RGB 4:4:4 colour. This bandwidth ceiling means the switch suits productivity and high-refresh gaming but cannot carry 4K at 120 Hz or 8K signals. Buyers needing higher refresh at 4K or more than two computer ports should look elsewhere.

Questions about this item

Does the LUOM OZK3-1 require any firmware updates or have user-replaceable components that need servicing over time?

The unit has no user-serviceable parts and no firmware update mechanism is described. The IR remote uses a standard AAA battery which will need occasional replacement.

What is the first limitation reached when running two 4K 60 Hz displays continuously through the HDMI 2.0b ports?

The HDMI 2.0b interface caps video bandwidth at 4K 60 Hz RGB 4:4:4, so higher refresh rates such as 1080p 144 Hz are only possible at lower resolutions or colour depths.

How much power does the switch draw and does it generate noticeable heat when left on all day?

It is powered by an included USB power cable drawing from a standard 5 V USB source, so consumption is low and the compact enclosure stays cool during extended use.
