Two-Port 8K HDMI 2.1 KVM Switch

The LUOM OZK4 is a two-port HDMI 2.1 KVM switch that lets one keyboard, mouse and monitor control two computers. It accepts two HDMI 2.1 inputs and two USB-C inputs, then outputs a single HDMI 2.1 signal. Four USB 3.0 ports provide shared peripheral connectivity for keyboards, mice, printers or storage devices.

For dual-system users needing 8K or high-refresh 4K

This switch suits professionals or enthusiasts who alternate between two PCs, a PC and a laptop, or a PC and a console while keeping one desktop setup. It does not suit anyone who must control three or more computers simultaneously, or who requires automatic timed switching beyond the fixed three-second AutoScan interval.

Handles 8K at 60 Hz and 4K at 120 Hz

The device supports resolutions up to 7680×4320 at 60 Hz and 3840×2160 at 120 Hz, plus 1080p at 240 Hz. Bandwidth headroom covers current high-refresh gaming monitors and 8K productivity displays. It runs out when a source demands throughput beyond HDMI 2.1 specification or when more than two computers need simultaneous access.

Questions about this item

Do I need to provide my own HDMI 2.1 cables to connect two computers and one monitor to the OZK4?

Yes, the switch has two HDMI 2.1 inputs and one HDMI 2.1 output, so you will need three HDMI 2.1 cables to link both sources and the display.

Will my existing USB 3.0 keyboard, mouse and printer work through the switch without extra drivers?

The unit provides four USB 3.0 ports for peripherals and supports Windows, macOS and Linux with plug‑and‑play operation, so standard USB 3.0 devices work immediately.

How can I confirm the switch is passing an 8K 60 Hz signal after I set it up?

Check your monitor’s on‑screen information or graphics‑driver control panel; it should report 7680×4320 at 60 Hz when the source is set to that resolution.
