Two-Computer HDMI 2.1 KVM Switch

The Jansicotek OZK4 lets a single keyboard, mouse and monitor control two computers. It accepts HDMI and USB-C inputs from each system and provides four USB 3.0 ports for peripherals. Manual switching and a three-second auto-scan interval give instant access. The aluminium-alloy shell resists interference and runs without drivers on Windows, macOS and Linux.

Replaces Separate Cables And Manual Swapping

Users who currently unplug HDMI and USB leads when moving between a desktop and a laptop can keep both connected. The jump is worth it when both sources need 4K at 120 Hz or 8K at 60 Hz on the same display. Hot-key switching removes the need to reach behind the monitor. The unit does not suit setups that require more than two computer inputs.

Handles 48 Gbps Bandwidth For 8K 60 Hz And 4K 120 Hz

The switch passes full 48 Gbps bandwidth, supporting 7680×4320 at 60 Hz and 3840×2160 at 120 Hz with 4:4:4 chroma. HDCP 2.3 protects premium content. Four USB 3.0 ports share mice, keyboards, storage drives, printers and cameras. It runs out of headroom when a third computer must be added or when bandwidth above 48 Gbps is required.

Questions about this item

What are the exact dimensions of the OZK4 so I can check it fits on my desk?

The unit measures 5.43 × 5.35 × 1.46 inches (111.8 × 63.2 × 24.5 mm) and weighs 9.52 ounces.

How do I connect both PCs and avoid the common mistake of swapping the HDMI and USB-C cables?

Connect each PC using one HDMI 2.1 cable and one USB-C cable to the matching input pair; the front-panel LED shows which port is active.

Will the aluminum-alloy shell need any thermal paste or fan cleaning over time?

No moving parts or thermal interfaces are used; the passive aluminum shell only requires occasional dusting of the vents.
