Dual USB-C 8K KVM Switch

The ESTONE TJ-A0126 connects two USB-C computers to a single DisplayPort 1.4 monitor and three USB 2.0 peripherals. It is built for users who need to share one display, keyboard, mouse and printer between two laptops or desktops without re-plugging cables. Manual switching and a three-second auto-scan interval give direct control over the active system.

Passive aluminium chassis runs silent

The aluminium alloy shell dissipates heat without a fan, so the unit adds no audible noise to the desk. Power is drawn from the included USB-A to USB-C cable, keeping the external power requirement minimal. Video bandwidth reaches 32.4 Gbps over DisplayPort 1.4, while USB 2.0 peripherals operate at 480 Mbps.

Front-panel button and LED status

A physical select button switches the active computer instantly, and LED indicators show which port is live. Two USB-C input ports accept standard USB-C Gen-2 cables for host connection, while the single DisplayPort 1.4 output drives resolutions up to 7680×4320 at 60 Hz or 4K at 144 Hz. Three USB-A 2.0 ports share peripherals between both hosts. Not suited for users who need more than one video output or USB 3.x peripheral speeds.

Questions about this item

How do I install the ESTONE TJ-A0126 KVM switch and what step is often missed?

Connect both PCs with the supplied USB-C Gen-2 cables to the two input ports, link your monitor to the DisplayPort 1.4 output, attach peripherals to the three USB 2.0 ports, then plug the USB-A to USB-C power cable into a USB-A source; the switch will not operate without this power connection.

What maintenance or replacement will the ESTONE TJ-A0126 need over time?

The aluminium chassis and passive design have no moving parts or filters; only the supplied USB-C Gen-2 cables or your own DisplayPort 1.4 cable may need replacement if they become damaged or if you require longer lengths.

What limit appears first during sustained use of the ESTONE TJ-A0126?

The USB 2.0 peripheral ports are capped at 480 Mbps, so high-throughput devices such as external SSDs will hit that bandwidth ceiling long before the 32.4 Gbps DisplayPort 1.4 video path reaches its maximum.
