LUOM TJ-A036 MST Hub

The LUOM TJ-A036 is a three-port DisplayPort 1.4 Multi-Stream Transport hub that lets one DP source drive three monitors. It suits professionals who need extended desktop space across multiple high-resolution panels. The device accepts a single DisplayPort 1.4 input and provides three DisplayPort 1.4 outputs. It supports mirror and extended modes for flexible workstation layouts.

Installation and Common Issues

Connect the hub to a DisplayPort 1.4 source, attach up to three displays, and plug the included USB-A to Micro-B cable into a 5 V power source. The hub requires external power to operate reliably. Integrated graphics may lack the video memory or bandwidth to drive three streams, so a discrete GPU is recommended. macOS can only extend one additional screen in MST mode due to system limitations.

Pre-Purchase Checks

Verify your source device has a DisplayPort 1.4 output that supports MST. Confirm each monitor accepts DisplayPort 1.4 input and can handle the desired resolution and refresh rate. Ensure a 5 V USB power port is available for the supplied cable. Check that your graphics card can drive the total pixel count across all connected displays.

Questions about this item

How can I verify the LUOM TJ-A036 is driving three monitors in extended MST mode after setup?

Open Windows display settings and confirm three separate desktop areas appear at the expected resolutions such as 4K at 60 Hz each; the hub splits one DP 1.4 input into three DP 1.4 outputs using Multi-Stream Transfer.

What comes in the box with the LUOM TJ-A036 and what must I supply separately?

The package includes the DP splitter host, a USB-A to USB Micro-B power cable, and a user manual; you must provide a 5 V USB power source and three DisplayPort cables for the monitors.

Which resolution and refresh combination should I choose on the LUOM TJ-A036 for a single 8K display?

Select 7680×4320 at 30 Hz on the single active port; this is the maximum single-port resolution the hub supports over DisplayPort 1.4.
