Two-computer HDMI 2.1 KVM
The Jansicotek OZK4 lets you operate two computers from a single monitor, keyboard and mouse. It accepts two HDMI 2.1 inputs and one USB-C input per system, then routes video to one HDMI 2.1 output at up to 8K 60 Hz or 4K 120/144 Hz. Manual button or hotkey switching changes the active host instantly. The aluminium alloy shell resists interference and aids heat dissipation.
Four USB 3.0 ports and hotkey control
Four downstream USB 3.0 ports share printers, cameras, storage drives or wireless keyboard and mouse dongles between the two connected PCs. No driver installation is required on Windows XP through Windows 10, macOS, Linux or Unix. LED indicators show the active port, and an automatic scan mode cycles every three seconds for hands-free monitoring.
8K 60 Hz bandwidth with 48 Gbps headroom
The switch passes the full 48 Gbps HDMI 2.1 bandwidth, supporting 7680×4320 at 60 Hz, 4K at 120 or 144 Hz and 1080p at 240 Hz with 4:4:4 chroma sampling. HDCP 2.3 compliance keeps protected content flowing. It will not suit setups that need more than two computer ports or automatic switching based on signal detection.

Questions about this item
Do the mechanical switch button or the HDMI ports wear out after frequent daily switching?
The unit uses a manual push-button with LED indicators and solid-state HDMI 2.1 ports rated for 48 Gbps bandwidth; no moving parts inside the signal path, so normal daily switching does not degrade the video link.
What is the first limit reached when running 8K@60Hz content continuously through both inputs?
The 48 Gbps bandwidth ceiling of the HDMI 2.1 chipset is the hard limit; sustained 8K@60Hz 4:4:4 uses the full pipe, so any additional USB 3.0 traffic shares the same controller budget.
Does the aluminum enclosure stay cool and silent when the switch powers two computers and four USB 3.0 devices all day?
The fanless aluminum-alloy shell (111.8×63.2×24.5 mm) dissipates the low heat from the HDMI 2.1 switch chip and USB 3.0 hub without noise; surface temperature stays warm but safe to touch.
