Dual-Computer Dual-Monitor Control

The LUOM OZK3-1 is a 2×2 HDMI KVM matrix that lets one keyboard, one mouse and two displays command two computers or laptops. It targets home-office workers and streamers who need simultaneous extended desktops across both screens without unplugging cables. Buyers who require more than two host ports or single-monitor operation should look elsewhere.

Plug-and-Play With Button Hotkey Remote

Connect each host via its HDMI and USB-C or USB-A cables, attach two monitors and the bundled USB 3.0 hub, then power the unit. Switching is instant using front-panel buttons, configurable hotkeys or the IR remote. The only common issue is forgetting to enable HDCP 2.3 on a source, which blocks 4K 60 Hz handshake until the setting is changed.

HDMI 2.0b 4K 60 Hz 4:4:4 Support

The decisive spec is HDMI 2.0b with HDCP 2.3 delivering 3840×2160 at 60 Hz in full RGB 4:4:4, plus 1080p at 144 Hz for high-refresh gaming. If your workflow demands 4K above 60 Hz or 10-bit HDR, this matrix cannot meet that need.

Questions about this item

How do I confirm the LUOM OZK3-1 is switching both monitors at 4K 60 Hz after setup?

The LED indicators on the front panel show which computer is active on each HDMI output; verify both displays report 3840 x 2160 at 60 Hz in their OS settings.

What cables are included and what must I provide to connect two computers and two monitors?

The box contains two USB data cables, one USB power cable, an IR remote (no AAA battery) and a manual; you must supply two HDMI cables per computer (four total) for the dual-monitor links.

Which version of the OZK3-1 should I choose if I need 1080p at 144 Hz on one screen and 4K 60 Hz on the other?

The single model OZK3-1 handles both simultaneously — it supports 1080p at 144 Hz and 3840 x 2160 at 60 Hz on its two HDMI outputs without any version choice.
