Two-computer USB-C KVM with 8K output

The ESTONE OZK8 is a 2-port USB-C KVM switch that lets two laptops or desktops share one display and seven USB 2.0 peripherals. Each computer connects through a single USB-C cable carrying video, data and up to 100 W of Power Delivery 3.0 charging. A front-panel button toggles the active system in about three seconds, and LED indicators show which port is live.

For dual-laptop desks, not multi-monitor rigs

It suits users who dock two USB-C machines — such as a work MacBook and a personal laptop — to one high-resolution monitor, keyboard, mouse and printer. Buyers who need simultaneous video on two screens, or who must connect computers without USB-C video output, should look at a different KVM design.

Single DisplayPort 1.4 or HDMI 2.1 video port

The switch offers one video output that can run 7680×4320 at 60 Hz, 4K at up to 144 Hz, or 1080p at up to 165 Hz. If your workflow demands two independent monitor feeds, this single-output unit will not meet that requirement.

Questions about this item

How do I connect the two USB-C cables and the display cable so the switch powers on and shows 8K@60Hz?

Connect each laptop to the two USB-C input ports using the supplied 1.2 m USB Gen 2 cables, then link the single DisplayPort 1.4 or HDMI 2.1 output to the monitor with your own 8K-rated cable. The unit must also be powered through the dedicated USB-C power port on each PC connection, otherwise the switch will not operate.

Which parts will need replacement first with daily 8K switching?

The two 1.2 m USB-C Gen 2 cables and the external DisplayPort or HDMI cable are the only passive components that wear from repeated plugging and bending; the switch itself has no user-serviceable parts and the front-panel push button is rated for long-term use.

At what point does sustained 8K@60Hz output hit a hard limit?

The DisplayPort 1.4 and HDMI 2.1 outputs max out at 7680×4320 at 60 Hz with DSC, so any attempt to push higher refresh rates at 8K or to exceed the 480 Mbps USB 2.0 peripheral bandwidth will be the first bottlenecks encountered.
