LUOM TJ-A038 DisplayPort Switch

The LUOM TJ-A038 is a DisplayPort 1.4 switch that takes one DP input and provides simultaneous DisplayPort and HDMI 2.1 outputs. It handles 8K at 30 Hz and 4K at 120 Hz with 32.4 Gbps bandwidth. The unit supports both SST mirror and MST extended modes across Windows, Android and iOS devices.

Who this suits and who should look elsewhere

This switch suits users who need to drive a DisplayPort monitor and an HDMI display from a single DP source at up to 4K 120 Hz or 8K 30 Hz. It is not for buyers who require 1440p at 165 Hz or 144 Hz over the HDMI port, as those rates are only available on the DisplayPort output. Builders needing more than two outputs should consider a different solution.

The spec that decides fit

The key specification is the maximum resolution per mode: in MST extended mode each port delivers up to 4K at 60 Hz simultaneously, while a single port in SST mirror mode reaches 8K at 30 Hz or 4K at 120 Hz. External 5 V power via the included USB cable is required for operation.

Questions about this item

Should I pick the DisplayPort or HDMI output for my 4K 120 Hz monitor?

Use the DisplayPort output for 4K at 120 Hz; the HDMI port is limited to 4K at 60 Hz for high refresh rates above 60 Hz.

What does the 8K 30 Hz rating mean when I connect both screens?

In extended MST mode each port can reach 8K at 30 Hz or 4K at 120 Hz; with both active simultaneously the maximum drops to 4K at 60 Hz per display.

Does the DisplayPort 1.4 input limit bandwidth to 32.4 Gbps?

Yes, the DP 1.4 input caps total bandwidth at 32.4 Gbps, which governs the highest resolution and refresh combinations the splitter can deliver.
