Three-Port DisplayPort 1.4 MST Hub

This active hub connects three independent DisplayPort monitors to a single Windows computer using Multi-Stream Transport. It supports 7.1-channel audio pass-through and is powered by the included Micro-USB cable. The Synaptics VMM5330 chipset drives the conversion.

Active Design with Male-to-Female Connectors

The unit has one DisplayPort 1.4 male input and three DisplayPort 1.4 female outputs in a compact black enclosure. Active circuitry maintains signal integrity for UHD resolutions up to 7680x4320 at 30Hz on a single display or 4K across all three ports. HDR support expands contrast ratio and colour accuracy.

Verify Windows MST Support and Cable Lengths

Confirm the host system's graphics output supports DisplayPort 1.4 MST for three independent streams; macOS does not support MST for extended desktops. Each attached monitor requires a DisplayPort cable no longer than 6.6 ft (2 m) to meet the specified maximum distance. Ensure a spare USB port is available for the hub's power cable.

Questions about this item

What does the DisplayPort 1.4 interface cap at for resolution and refresh rate on a single monitor versus three monitors?

The hub supports 7680x4320 at 30 Hz on one display or 4K resolution across all three connected monitors.

What physical space and power connections does the MST14DP123DP need to fit and run?

It measures 0.55 by 4.13 by 1.69 inches, weighs 0.12 lbs, and draws power from the included micro-USB cable.

How is this hub installed on Windows, and what step do users often miss?

Connect the DisplayPort male end to the PC, attach up to three monitors to the female ports, plug in the micro-USB power cable, then enable MST in the GPU control panel so all three screens appear as independent displays.
