One-to-three DisplayPort hub

The LUOM TJ-A036 splits a single DisplayPort 1.4 signal into three independent outputs. It supports MST expansion for three different screens or SST mirroring for three identical images. The device requires USB power and a Windows host with a discrete graphics card that implements MST.

Windows multi-monitor setups only

Builders running Windows on a discrete GPU can drive three 4K displays at 60 Hz each or a single 8K panel at 30 Hz. Mac and Android systems are limited to one extended screen, and integrated graphics often lack the video memory or bit width to operate the hub reliably.

32.4 Gbps bandwidth ceiling

The 32.4 Gbps link caps combined throughput, so three 4K outputs run at 60 Hz while a single port can reach 4K 144 Hz or 8K 30 Hz. Exceeding this aggregate bandwidth forces lower resolutions or refresh rates across the connected displays.

Questions about this item

Does the LUOM TJ-A036 generate noticeable heat or fan noise when running three 4K displays all day?

The hub is passively cooled with no fan, so it produces no audible noise; its slim aluminium shell stays warm but within normal operating limits during continuous multi-monitor use.

What must my graphics card already support for the MST triple-display mode to work?

Your GPU must provide a DisplayPort 1.4 output with MST capability and enough bandwidth for three streams; integrated graphics often lack the required video memory and bit width, so a discrete card is recommended.

Will the hub downscale correctly if I connect two older 1080p monitors alongside one new 4K panel?

Yes, each port negotiates independently — the 4K display can run at 144 Hz while the 1080p screens operate at up to 240 Hz, all driven from the single DP 1.4 input.
