Two-Computer KVM Switch

The ESTONE OZK1-New lets two computers share a single HDMI monitor, three USB 3.0 peripherals and one RJ45 network connection. A front-panel button and an included infrared remote both change the active system. LED indicators show which port is currently selected. The unit ships with two USB cables and a printed manual.

Thermal and Power Behaviour

No fan or active cooling is fitted, so the switch runs silently during normal operation. Power is drawn from the connected computers through the USB links, eliminating the need for an external adapter. Typical draw stays well within standard USB 3.0 current limits. The passive design means there is no audible noise and no heat-related throttling.

Build and Connectivity Notes

The enclosure measures 5.43 by 5.35 by 1.46 inches and weighs 9.52 ounces, making it compact enough for a crowded desk. Three USB 3.0 Type-A ports support keyboards, mice, storage drives, printers, scanners or cameras at up to 5 Gbps. The single RJ45 port provides a 100 Mbps network link for the active computer. HDMI 2.0b with HDCP 2.3 carries video at 7680 x 4320 30 Hz or 4K 120 Hz.

Questions about this item

How do I connect both computers to the ESTONE OZK1-New KVM switch and which step is most often missed?

Connect each computer using one HDMI cable and one USB data cable to the corresponding PC ports, then attach the monitor to the single HDMI output and shared USB devices to the three USB 3.0 ports; the step most often missed is plugging both USB cables in, which is required for keyboard and mouse switching to work.

What maintenance or replacement will the ESTONE OZK1-New KVM switch need over time?

The unit has no user-serviceable parts or consumables; the included remote controller uses a replaceable coin-cell battery that will eventually need changing, and cables can be swapped if they become damaged.

What is the first limit I will hit when running the ESTONE OZK1-New at 4K 120 Hz for long sessions?

The HDMI 2.0b interface caps sustained 4K output at 120 Hz with RGB 8:8:8 colour, so bandwidth is the limiting factor before any thermal or switching constraint appears.
