2x1 Switch and 1x2 Splitter

The ESTONE TJ-A034 is a bi-directional USB-C video switch that works as a 2x1 switch connecting two source devices to one display or as a 1x2 splitter sending one source to two displays. It suits users who need to share a single USB-C monitor between a laptop and a desktop or duplicate a signal to two screens without unplugging cables.

8K 30Hz and 4K 120Hz Headroom

The switch passes video up to 8K at 30Hz and 4K at 120Hz, with additional support for 5K at 60Hz, 1440p at up to 165Hz and 1080p at up to 165Hz. Data moves at 10Gbps over USB 3.1 Gen 2. The 100W Power Delivery keeps a connected host charged while the switch is powered, but two displays cannot show content simultaneously.

External Power and Cable Limits

A 5V DC jack and a supplied USB-A to Micro-B cable provide mandatory external power for stable operation. The box also includes a 50cm tethered USB-C cable and a user manual. The manufacturer notes that cables longer than 1.5 metres between the switch and devices may cause flicker or signal loss, and docking stations or hubs should not be connected.

Questions about this item

Will this switch pass 4K 120 Hz from a USB-C laptop to an older 4K 60 Hz monitor?

Yes, the switch supports 4K at 120 Hz and will negotiate the highest rate both ends can handle, so a 60 Hz display will simply run at 60 Hz.

How do I confirm the 10 Gbps data path is active after connecting?

Open your OS device manager or system report and verify the link speed shows 10 Gbps for the attached USB device.

The box lists a 50 cm cable and a USB-A to Micro-B cable; do I still need a USB-C 10 Gbps cable for the video link?

Yes, the note states a USB 3.1 Gen 2 cable is not included and must be purchased separately for full 10 Gbps and 4K 120 Hz operation.
