Dual-computer dual-monitor KVM
The STARNOONTEK OZK3 is a 2-port HDMI KVM switch that lets one keyboard, one mouse and two monitors control two computers or game consoles. It accepts HDMI and USB-C inputs from each host and provides two HDMI outputs plus USB 3.0 peripheral ports for shared devices. The unit is new and includes an IR remote for convenient switching.
HDMI 2.0 bandwidth and audio limits
Video is carried over HDMI 2.0b with HDCP 2.2, so the practical ceiling is 4K at 60 Hz or 1080p at 144 Hz; the advertised 8K at 60 Hz exceeds the interface’s rated throughput and cannot be delivered. Audio is extracted through a 3.5 mm jack with an internal DAC for stereo output. Switching is manual via front buttons, hotkeys or the remote, with a fixed 3-second auto-scan interval.
4K 60 Hz decides the fit
If your workflow requires two displays at 3840×2160 60 Hz from two hosts, this switch meets that requirement. It will not drive higher refresh rates at 4K, nor will it pass HDR metadata or variable-refresh-rate signals beyond the HDMI 2.0 specification. Buyers needing 4K 120 Hz or 8K output should look elsewhere.

Questions about this item
Which STARNOONTEK OZK3 version should I choose for dual-monitor 4K@120Hz switching?
The OZK3 is a single 2-port dual-monitor model that supports 4K@120Hz and 8K@60Hz via HDMI 2.0b, so there is only one version to select.
What does the 4K@120Hz rating mean when I connect two PCs and two monitors?
Each HDMI 2.0b output can deliver 3840×2160 at 120 Hz, so both monitors run at that refresh rate simultaneously when the source PCs output it.
What does the HDMI 2.0b interface cap in practice?
HDMI 2.0b limits video to 7680×4320 at 60 Hz or 3840×2160 at 120 Hz with HDCP 2.2, and USB 3.0 ports share 5 Gbps bandwidth.
