Two-PC KVM for 4K@60Hz workflows

The ESTONE OZK2 lets you control two computers from one HDMI monitor and four USB 3.0 peripherals with a single button press. It supports video up to 3840 x 2160 at 60 Hz and passes USB 3.0 data through four downstream ports. No driver installation is required on Windows XP, 7, 10, macOS, Linux or Unix. An aluminium alloy shell provides shielding and heat dissipation for stable operation.

Suits dual-desktop users who share one display

Ideal for anyone toggling between a work laptop and a home PC, or a Mac and a Linux box, while keeping keyboard, mouse, printer and camera connected. The front-panel switch and three-second auto-scan make changes instant. Buyers who need more than two computer inputs, require DisplayPort or USB-C video, or want remote switching via IR or hotkey should look at other models.

Steady 4K output during long sessions

The metal enclosure acts as a heatsink, so signal integrity holds up during extended workdays without thermal throttling. HDMI 2.0 and HDCP 2.2 handshake remain stable at 4K 60 Hz, and USB 3.0 ports maintain 5 Gbps throughput for drives and peripherals. LED indicators confirm the active port at a glance. Power is drawn from the included USB cable, so no external adapter is needed.

Questions about this item

Do I need to supply my own HDMI cables to connect both computers to the ESTONE OZK2?

Yes, the package includes two USB data cables and one USB power cable, but no HDMI cables; you must provide two HDMI cables to link each computer to the switch.

Will a wireless keyboard and mouse that use a single USB receiver work through the four USB 3.0 ports on this KVM?

The switch presents four USB 3.0 ports to the active computer, so a single wireless receiver plugged into one port will control whichever system is currently selected.

How can I confirm the ESTONE OZK2 is delivering 4K at 60 Hz after I connect everything?

The front-panel LED shows which computer is active; verify in the OS display settings that the monitor reports 3840×2160 at 60 Hz.
