USB-C bidirectional switch 8K

The ESTONE TJ-A034 is a bi-directional USB-C switch that operates as either a 2x1 source selector or a 1x2 display splitter. It carries video, 10 Gbps data and up to 100 W power delivery over a single 50 cm cable. External 5 V DC power is required via the included USB-A to Micro-B cable.

Suits single-display workflows, not dual-view

This switch serves users who need to toggle between two laptops on one monitor or send one laptop to either of two screens. It does not support simultaneous output on both displays, so buyers wanting extended-desktop or cloned dual-view should look elsewhere. Docking stations or hubs connected downstream may cause flicker or signal loss.

8K 30 Hz or 4K 120 Hz ceiling

The maximum video specification is 8K at 30 Hz and 4K at 120 Hz, with 1440p up to 165 Hz and 1080p up to 165 Hz depending on host, cable and display capabilities. Bandwidth tops out at 10 Gbps under USB 3.1 Gen 2, and power delivery reaches 100 W when the supply allows.

Questions about this item

What bandwidth does the USB 3.1 Gen 2 interface cap at in practice?

The switch is rated for 10Gbps data transfer under USB 3.1 Gen 2, so that is the practical ceiling for connected storage or peripherals.

What physical space and power connections does the unit need to mount?

It measures 12 by 6 by 0.08 inches and requires a 5 V DC jack of 1.35 by 3.5 mm plus the supplied USB-A to Micro-B cable for external power.

How do I install the switch and what step is commonly missed?

Connect the included USB-A to Micro-B cable to the DC jack for power, attach your source and display cables to the Type-C ports, then press the Select button to toggle modes; the step often missed is powering the unit before linking video sources.
