Two-way USB-C video switch

The ESTONE TJ-A034 is a bi-directional USB-C switch that works as a 2x1 selector or a 1x2 splitter. It links two source devices to one display or one source to two displays for computers, phones and monitors.

Passive operation with external power

The unit draws no power of its own and requires the supplied USB-A-to-DC cable for operation. It delivers up to 100W Power Delivery to connected devices while passing 10Gbps USB3.1 Gen2 data and 8K@30Hz video.

Bundled cable and manual only

A 50cm USB-A-to-Micro-B cable and a user manual are included. No USB3.1 Gen2 video cable is supplied, so a separate high-quality cable under 1.5m is needed to avoid flicker or signal loss.

Questions about this item

How do I connect the 5 V DC power jack and which cable do I use?

Plug the supplied USB-A to Micro-B cable into the 1.35 × 3.5 mm DC jack and a USB-A power source; the switch will not operate without external power.

What resolution drops first if I use a cable longer than 1.5 metres?

The 8K@30Hz signal becomes unstable first; the manual warns that cables over 1.5 m cause flicker or a black screen.

At what data rate does the 10 Gbps limit appear during large file transfers?

The USB 3.1 Gen 2 interface caps sustained throughput at 10 Gbps, so long sequential copies will hit that ceiling.
