Product identity

The ESTONE TJ-A038 is a DisplayPort 1.4 MST hub that splits one source into simultaneous DisplayPort and HDMI outputs. It serves creators, educators and commercial installers who need to mirror or extend a desktop across two screens from a single DP port.

Thermals noise power

The aluminium enclosure measures 12 x 6 x 0.08 inches and weighs 1.2 ounces, passively dissipating heat without a fan. An external DC 5 V USB power lead is required for operation, drawing minimal current from the host system.

Questions about this item

How do I install the ESTONE TJ-A038 DisplayPort switch, and what step is often missed?

Connect the DisplayPort 1.4 source to the input, attach one DisplayPort 1.4 and one HDMI 2.1 display to the outputs, then plug the included DC 5 V USB power cable into a live USB port; the hub will not function without external power.

What maintenance or replacement will the ESTONE TJ-A038 need over time?

No user-serviceable parts are inside; keep the USB power cable and connectors free of dust, and replace the cable only if it becomes damaged or the power connection becomes unreliable.

What limit appears first when the ESTONE TJ-A038 runs continuously at high resolution?

The 32.4 Gbps bandwidth ceiling caps simultaneous output to 8K at 30 Hz or 4K at 120 Hz; pushing both ports beyond that will force a lower refresh rate or resolution.
