Two-PC Control, One Display

The Jansicotek OZK4 is an HDMI 2.1 KVM switch that lets you operate two computers from a single keyboard, mouse and monitor. It accepts both HDMI and USB-C video inputs from each system and provides four USB 3.0 ports for shared peripherals such as printers, cameras or storage devices. Manual button switching and hotkey commands give instant control without software drivers.

HDMI 2.1 Bandwidth and Switching Limits

The switch passes up to 48 Gbps over HDMI 2.1 with HDCP 2.3 support, enabling 8K at 60 Hz or 4K at 120 Hz. Auto-scan cycles every three seconds if enabled, while LED indicators show the active port. The USB-C inputs carry video only; they do not supply power to connected laptops. Wireless keyboard and mouse dongles are recognised through the USB hub.

Resolution Headroom and Peripheral Capacity

Supported video modes include 1080p at 240 Hz, 4K at 60 Hz and 120 Hz, and full 8K at 60 Hz with 4:4:4 chroma sampling. Four USB 3.0 ports handle high-speed data devices alongside standard input gear. The aluminium chassis measures 111.8 by 63.2 by 24.5 millimetres and weighs 9.52 ounces. Buyers needing more than two computer inputs or dual-monitor output should consider a different switch.

Questions about this item

Which version should I choose for two computers sharing one 8K monitor?

The OZK4 model provides two HDMI 2.1 inputs and one HDMI 2.1 output, so a single unit handles both PCs and the 8K@60Hz display.

What does 8K@60Hz mean when I connect my PC and monitor?

It supports up to 7680×4320 at 60 Hz with full 48 Gbps bandwidth, plus 4K@120Hz and 1080P@240Hz for lower-resolution sources.

How does the HDMI 2.1 interface limit what I can run?

HDMI 2.1 caps video at 8K@60Hz and 48 Gbps; the switch also passes HDCP 2.3 and uses USB 3.0 hubs for keyboard, mouse and peripherals.
