Two-Port HDMI 2.1 KVM for 8K Workflows

The LUOM OZK4 is a 2-in-1-out KVM switch that lets one keyboard, mouse and monitor control two computers. It supports resolutions up to 7680×4320 at 60 Hz and 3840×2160 at 120 Hz. HDMI 2.1 and HDCP 2.3 compliance keeps protected content flowing. The unit works with Windows, macOS, Linux and Unix without drivers.

USB-C Inputs and Four USB 3.0 Ports Free Peripherals

Each computer connects through HDMI 2.1 and USB-C, while the front provides four USB 3.0 ports for keyboards, mice, storage, printers or cameras. A single HDMI 2.1 output feeds the display. Switching is handled by a front-panel button or the Ctrl+Shift+1/2 hotkey combination. Auto-scan cycles every 3 seconds and LEDs show the active port.

Suits Dual-PC Desks Needing High-Refresh 8K

Ideal for users who share one high-resolution screen between a workstation and a laptop or console. The four USB 3.0 ports handle high-current drives and multiple accessories. Builders who need more than two sources, DisplayPort inputs or remote switching should look at a different class of KVM.

Questions about this item

Does the HDMI 2.1 bandwidth limit the 8K@60Hz signal to 10‑bit colour or 4:2:0 chroma?

The switch passes HDMI 2.1 with HDCP 2.3, supporting 7680×4320 at 60 Hz and 3840×2160 at 120 Hz as listed.

Does the unit get hot or draw enough power to need a fan when both PCs and USB 3.0 drives are active all day?

It is a compact passive design at 111.8×63.2×24.5 mm with no fan mentioned; power comes from the connected USB‑C and USB 3.0 ports.

Do both computers need USB‑C video output, or can one use HDMI while the other uses USB‑C?

Each of the two ports accepts HDMI 2.1 and USB‑C simultaneously, so one PC can connect via HDMI and the other via USB‑C.
