2-Port HDMI 2.1 KVM Switch

The LUOM OZK4 is a new 2-port KVM switch that lets one keyboard, mouse and monitor control two computers. It accepts both HDMI 2.1 and USB-C inputs from each host and delivers a single HDMI 2.1 output up to 7680×4320 at 60 Hz. An aluminium alloy shell houses four USB 3.0 peripheral ports for shared devices.

Ideal for dual-PC desk setups

Suits users who need to toggle a MacBook and a Windows PC, or a workstation and a gaming rig, on one 4K 120 Hz or 8K 60 Hz display. Switching is manual via a front button or a Ctrl+Shift+1/2 hotkey; auto-scan runs at 3-second intervals. Buyers who need automatic port detection or more than two host connections should consider other KVM types.

Single HDMI 2.1 output at 8K 60 Hz

The decisive specification is the single HDMI 2.1 output limited to 7680×4320 at 60 Hz with HDCP 2.3 support. If the target monitor requires higher refresh rates at 8K, or dual-monitor output, this switch will not meet that requirement.

Questions about this item

What does the 8K 60 Hz rating mean when I connect this to my monitor?

The switch passes a 7680×4320 signal at 60 Hz from either computer to the single HDMI 2.1 output, so your display receives the full 8K frame rate without compression.

Which HDMI version limits the bandwidth, and what resolutions does it actually support?

HDMI 2.1 with HDCP 2.3 caps the link at the 8K 60 Hz ceiling while also handling 4K at 120 Hz and 1080p at 240 Hz for high-refresh gaming.

How much desk space does the aluminium chassis need, and what cables plug into the front?

The unit measures 111.8 × 63.2 × 24.5 mm and presents two HDMI 2.1 inputs, two USB-C inputs and four USB 3.0 peripheral ports on the front panel.
