Two-computer HDMI KVM

The ESTONE OZK2 switches a single 4K display and four USB 3.0 peripherals between two computers with a manual button press. It accepts two HDMI plus USB upstream connections and provides one HDMI output plus four downstream USB 3.0 ports. No driver installation is required on Windows, macOS, Linux or Unix systems.

Replaces cable-swapping and software KVMs

Users who currently unplug HDMI and USB cables to change machines, or who rely on network-based sharing tools, gain instant hardware switching without latency or configuration. The jump is worth it when desk space is limited and both computers must stay powered and connected to the same monitor, keyboard, mouse and printer simultaneously.

Sustained 4K 60 Hz operation

An aluminium-alloy shell dissipates heat and shields signals during continuous 3840 x 2160 at 60 Hz output. Auto-scan holds each port for three seconds if enabled, while the metal housing maintains stable video and USB 3.0 throughput across long work sessions without thermal throttling or electromagnetic interference.

Questions about this item

What cables are needed to connect two computers and one monitor to the ESTONE OZK2?

Connect each computer using one HDMI cable and one USB data cable. Connect the monitor to the single HDMI output. The box includes two USB data cables and one USB power cable; HDMI cables are not included.

How do I switch between the two connected PCs on the OZK2?

Press the one-key switch button on the top panel to toggle between the two computers. The LED indicators show the active port. Avoid rapid presses; allow the 3-second auto-scan interval to complete if using that mode.

Will I need to replace the USB power cable or power supply for the OZK2 over time?

The switch draws power through the included USB power cable from a standard USB port or charger. No internal battery or proprietary power supply exists. Replace the cable only if it becomes physically damaged.
