USB-C 8K Bi-Directional Switch

The ESTONE TJ-A034 is a compact USB-C switch that operates in two modes. It can connect two source devices to one display or one source to two displays. It handles video, data and up to 100W power delivery for laptops, phones or tablets.

Limits of USB 3.1 Gen 2 and DisplayPort 1.4

The link tops out at 10Gbps, so 8K is limited to 30Hz while 4K reaches 120Hz and 1080p can hit 165Hz. The 50cm cable and 1.5m maximum recommended length restrict placement. Two screens cannot show content at the same time.

Installation notes and common issues

External 5V DC power is mandatory; the unit ships with a USB-A to Micro-B cable for that purpose. Connecting a Thunderbolt dock or hub causes flicker or signal loss. Long cables between the switch and devices also lead to black screens.

Questions about this item

How do I decide between the 2x1 switch and 1x2 splitter modes on the TJ-A034?

Use 2x1 to connect two source devices to one display, or 1x2 to send one source to two displays. Press the Select button to change the active output. Only one display shows at a time.

What resolution will I actually get from the 8K@30Hz rating on my monitor?

The switch passes up to 8K at 30 Hz, 4K at 120 Hz or 1080p at 165 Hz. The final resolution depends on your source device, monitor and the cables you use.

Does the USB 3.1 Gen 2 10Gbps port also carry the 100 W Power Delivery?

Yes. The single USB-C connector handles 10 Gbps data, DisplayPort 1.4 video and up to 100 W PD simultaneously. External 5 V DC power is required via the supplied USB-A to Micro-B cable.
