1×3 DisplayPort 1.4 Splitter

This LUOM TJ-A036 splitter takes one DisplayPort 1.4 source and drives three DisplayPort 1.4 displays. It suits professionals who need triple-monitor workstations or gamers seeking high-refresh surround setups from a single GPU output.

Bandwidth and MST limits

The 32.4 Gbps link caps total throughput, so three simultaneous 4K panels run at 60 Hz while a single port can reach 8K at 30 Hz or 4K at 144 Hz. Apple macOS only mirrors in MST mode, restricting multi-stream expansion to one extended screen.

Source and power checks

Verify your graphics card supports DisplayPort 1.4 MST; integrated graphics often lack the memory bandwidth for three streams. The unit requires the included USB-A to Micro-B cable for power, so a free USB port or adapter must be available.

Questions about this item

Should I pick the 8K30 Hz version or the 4K144 Hz version?

This single unit handles both: one port can run 7680×4320 at 30 Hz or 3840×2160 at 144 Hz, so you do not choose between versions.

What does the 32.4 Gbps bandwidth mean when I connect three monitors?

In MST mode the splitter drives three displays at 3840×2160 60 Hz simultaneously; a single port can reach 7680×4320 30 Hz or 3840×2160 144 Hz.

Does DisplayPort 1.4 cap the refresh rate at 4K?

DP 1.4 on this hub supports 3840×2160 at 144 Hz on one port and 60 Hz across all three ports in MST mode.
