Dual DisplayPort HDMI splitter for creators

The LUOM TJ-A038 splits one DisplayPort 1.4 source into simultaneous DisplayPort 1.4 and HDMI 2.1 outputs. It supports SST mirror and MST extended modes for dual-monitor workflows. Compatible with Windows, Android and iOS systems. Requires the included USB power cable for operation.

Upgrade from single-port adapters

Replaces basic single-output dongles when you need two active displays from one GPU port. In MST mode each output can reach 4K@60Hz together, or one port can hit 8K@30Hz or 4K@120Hz alone. The jump is worth it for signage, streaming or multi-tasking setups that demand simultaneous high-refresh 1440p or 4K signals.

Check GPU port and cable specs

Verify your graphics card provides a DisplayPort 1.4 output with MST support for extended desktop. Use certified DP 1.4 and HDMI 2.1 cables rated for 32.4 Gbps bandwidth. Note that 165 Hz and 144 Hz at 1440p are not supported on the HDMI port. Ensure a free USB port or charger for the required 5 V power line.

Questions about this item

What size opening does the 12 x 6 x 0.08 inch switch need to fit in a rack or shelf?

The switch measures 12 inches long, 6 inches wide and 0.08 inches thick, so allow at least that footprint plus cable clearance.

Which step do people skip when installing the DP 1.4 to DP 1.4 + HDMI 2.1 switch?

Connect the included DC 5 V USB power cable before linking the DisplayPort source and the two displays; the unit will not pass signal without external power.

What will need replacement first on the LUOM TJ-A038 switch?

The USB power cable or the DisplayPort and HDMI cables will wear out before the switch itself, so keep spares for those.
