Dual 4K matrix control

The LUOM OZK3-1 is a 2×2 HDMI 2.0b KVM matrix switch that lets two computers share one keyboard, one mouse and two monitors. It supports 4K at 60 Hz and 1080p at 144 Hz with HDCP 2.3 compliance. USB 3.0 ports and audio pass-through are included for peripheral sharing.

Suits multi-system desks, not single-PC setups

This unit is built for users who need simultaneous dual-display access to two hosts such as a workstation and a laptop or a console. Buyers who only need to switch a single monitor between computers should consider a simpler 2-port KVM without matrix routing.

HDMI 2.0b with HDCP 2.3 decides compatibility

The switch passes 4K 60 Hz 4:4:4 signals and 1080p high-refresh rates only when both source and display support HDMI 2.0b and HDCP 2.3. Older HDMI 1.4 ports will limit resolution and refresh to their native maximums.

Questions about this item

Should I choose the 1080p 144 Hz or the 4K 60 Hz mode for my dual-monitor setup?

Pick 3840 x 2160 at 60 Hz when you need maximum desktop space across both screens; choose 1080p at 144 Hz if you prefer smoother motion for fast-paced games on either display.

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

Each HDMI output can deliver 3840 x 2160 at 60 Hz simultaneously, so both monitors show full 4K resolution without dropping to a lower refresh rate.

How does the HDMI 2.0b interface limit what I can run on the two ports?

The 2.0b link caps each port at 4K 60 Hz RGB 4:4:4 and HDCP 2.3, so higher refresh rates at 4K or 8K signals are not supported.
