3-Port DP MST Hub for Multi-Monitor Workstations

This DisplayPort 1.4 MST hub splits one DP source into three DP outputs. It enables mirror or extended desktop modes across three monitors from a single DisplayPort connection. The compact unit requires 5 V USB power and is aimed at professionals who need a high-resolution multi-display setup without adding graphics cards.

Suits MST-capable hosts needing three extended

Works with Windows and Android hosts that support DisplayPort MST. Apple macOS and iOS devices can only mirror or extend to one external screen due to OS limits. Integrated graphics may lack the bandwidth or memory width for three high-resolution streams, so a discrete GPU is recommended. Buyers without MST support on their source should consider a different topology.

8K@30 Hz single-stream

The hub delivers up to 8K at 30 Hz on one display, 4K at 60 Hz on two displays, or 4K at 60 Hz on all three simultaneously when the source allows. Maximum throughput is 32.4 Gbps over DisplayPort 1.4. This bandwidth ceiling is the key figure that determines whether your desired resolution and refresh-rate combination is achievable.

Questions about this item

What power connection does the 3-port DisplayPort MST switch require?

It needs a 5 V external power supply delivered through the included USB-A to USB Micro-B cable.

How do you enable three independent monitors instead of mirrored screens?

Select MST extended mode on the host system; SST mirror mode only duplicates the same image on all three outputs.

When might the USB power cable need replacing?

If the cable is damaged or the connector wears out, a standard USB-A to Micro-B lead can restore power to the switch.
