LUOM TJ-A038 DisplayPort Switch

The LUOM TJ-A038 is a DisplayPort 1.4 switcher that routes one DP input to simultaneous DP 1.4 and HDMI 2.1 outputs. It serves laptop or desktop users who need a single source displayed on two screens at once.

Bundled power cable and manual

A DC 5 V USB power lead is included because the unit requires external power for stable operation. The quick-start guide explains how to select SST mirror or MST extended modes for the connected displays.

Check DP version and cable rating

Verify that your source supports DisplayPort 1.4 and that both cables are rated for 32.4 Gbps bandwidth to reach 8K at 30 Hz or 4K at 120 Hz. HDMI output does not support 1440p at 165 Hz or 144 Hz.

Questions about this item

Does the DC 5 V power cable need periodic replacement?

The included DC 5 V cable is a standard USB power lead; replace it only if the connector or cable sheath shows physical damage.

What resolution ceiling appears first when both outputs run continuously?

In MST extended mode the two ports are limited to 4K@60 Hz simultaneously; single-port use can reach 8K@30 Hz or 4K@120 Hz.

How warm does the aluminium housing get during all-day operation?

The unit draws power only from the supplied 5 V USB line and has no fan; it runs warm to the touch but stays within normal operating temperature for a passive 32.4 Gbps switch.
