2-Port DP 1.4 Splitter with Audio

The LUOM OZFD splits one DisplayPort 1.4 input into two DisplayPort outputs while extracting audio through a 3.5 mm jack. It handles video at 3840x2160@144Hz and passes the same signal to both displays in mirror mode or separate streams in MST extend mode. A 5V/2A external power adapter and USB-C power cable are included in the box.

Suits Windows multi-monitor setups.

Windows PCs can drive two different 4K images at up to 120Hz each using MST extend mode. Mac and Linux systems only support mirror mode, so buyers who need independent screens on those platforms should look elsewhere. The unit also lacks HDMI outputs, so displays without DisplayPort inputs cannot be connected directly.

32.4 Gbps bandwidth decides 4K 144Hz single

The 32.4 Gbps link carries one 3840x2160@144Hz stream in SST mirror mode or two 3840x2160@120Hz streams in MST extend mode. If your workflow demands 144Hz on both monitors simultaneously, this splitter cannot deliver that configuration.

Questions about this item

Do I need a separate power source for the LUOM OZFD splitter to run two 4K monitors?

Yes, the unit requires the included 5V/2A power adapter and USB-C cable; it does not draw enough power from the DisplayPort input alone.

Will my MacBook extend two different desktops across the two DisplayPort outputs?

No, macOS only supports mirror mode on this MST hub; extended desktops require a Windows host with a GPU that supports DisplayPort 1.4 MST.

How can I confirm the splitter is delivering 4K at 144 Hz to each monitor?

Check each display’s on-screen menu or OS display settings — both should report 3840x2160 at 144 Hz when using certified DisplayPort cables rated for 32.4 Gbps.
