ESTONE TJ-A036 DP 1.4 MST Hub

The ESTONE TJ-A036 is a DisplayPort 1.4 Multi-Stream Transport hub that splits one DP 1.4 input into three DP 1.4 outputs. It is built for users who need to drive three monitors from a single MST-capable graphics output.

Suits MST workstations; not for non-MST sources

This hub suits professionals building triple-monitor workstations where the host GPU supports DisplayPort MST. Buyers whose source device lacks MST capability should look elsewhere, as the extended desktop mode will not function. It also does not suit setups requiring more than three displays or bandwidth beyond 32.4 Gbps.

Includes USB-A to Micro-B power cable

The package supplies a USB-A to Micro-B cable for the required 5 V external power. This cable lets you draw power from a standard USB port or charger, ensuring stable operation for the 8K@30 Hz and 4K@144 Hz modes without a separate wall adapter. A user manual is also included.

Questions about this item

Does my graphics card need an MST-enabled DisplayPort 1.4 output to drive three monitors?

Yes, the hub requires a single MST-enabled DisplayPort 1.4 source to split the signal across three displays in extended mode.

Can I run two 4K@60Hz monitors and one 1440p@165Hz monitor simultaneously from this hub?

The hub supports dual 4K@60Hz with HDR off, and 1440p at up to 165Hz; total bandwidth is 32.4 Gbps, so that combination fits within the limit.

After connecting everything, how do I confirm the hub is operating in MST extended mode rather than SST mirror mode?

Open your OS display settings — if three distinct monitors appear and can be arranged side-by-side, MST extended mode is active.
