LUOM TJ-A038 DP 1.4 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 complies with DP 1.4, 1.3, 1.2 and 1.0 specifications and delivers up to 32.4 Gbps bandwidth. The unit supports SST mirror and MST extended modes for flexible display configurations.

For multi-display workstations and signage

This switch suits users who need to drive one DisplayPort monitor and one HDMI display from a single DP source, such as digital signage in schools, churches or conference rooms. It is not for buyers who require more than two outputs, need HDMI input, or want a passive adapter without external power. Gamers relying on 1440p at 165 Hz or 144 Hz over HDMI should note those rates are unsupported on the HDMI port.

Check source and cables before ordering

Verify your graphics card, monitors and operating system support the target resolutions and MST if you plan extended mode. Ensure you have a DisplayPort 1.4 cable for the input and suitable DP and HDMI cables for the outputs. A USB power source for the included DC 5 V line is required for operation.

Questions about this item

What DisplayPort cable and source version do I need for the switch to pass 8K at 30 Hz?

Use a DisplayPort 1.4 cable from a DP 1.4 source; the switch complies with DP 1.4, 1.3, 1.2 and 1.0 specifications.

Will my older DP 1.2 monitor still work when connected to the HDMI output alongside a newer display?

Yes, the HDMI output supports HDMI 2.1, 2.0, 1.4 and 1.3, so a DP 1.2 monitor via an adapter will function at its native resolution.

How can I confirm MST extended mode is active after plugging in both displays?

Open your OS display settings; you should see two separate desktops at up to 4K 60 Hz each when MST is enabled.
