  • Connect three 4K monitors from one DisplayPort 1.4 output using MST technology
  • Choose mirror, extended or panoramic video-wall modes for flexible workflows
  • Requires a DisplayPort 1.4 GPU that supports more than three external screens
  • Powered by USB 3.0 bus power; USB 2.0 does not supply enough current
  • Not compatible with macOS because Mac OS does not support MST technology

Triple 4K DisplayPort 1.4 MST Hub Splitter

The SIIG Triple 4K DisplayPort 1.4 MST Hub Splitter connects three DisplayPort monitors to a single DisplayPort 1.4 output using Multi-Stream Transport technology. It supports Mirror mode, Extended mode and Panoramic Video Wall mode for productivity setups. The hub requires a GPU that supports more than three external screens and draws power from a USB 3.0 port. MacOS is not supported.

Replaces single-monitor

This hub upgrades a single DisplayPort 1.4 output into three independent video streams, removing the need for additional graphics cards or docking stations. The upgrade is worthwhile when your GPU supports more than three external displays and you need simultaneous extended desktops. Intel HD Graphics limited to three total screens cannot drive three extra monitors through this device. USB 2.0 ports cannot supply sufficient power.

Sustained multi-display operation

Under continuous use the hub maintains three 4K streams through the DisplayPort 1.4 link without dropping to lower resolutions. The USB 3.0 power delivery remains stable during extended sessions, preventing the port-power brownouts that affect lesser-powered splitters. Fanless aluminium housing dissipates heat passively so thermal throttling does not occur during all-day workloads. MacOS systems will only mirror displays regardless of load.

Questions about this item

Does this MST hub need a separate power connection or does it draw power from the host?

It requires USB bus power from a USB 3.0 port; USB 2.0 or earlier does not supply enough power to drive the hub.

What is the correct order for connecting the USB power and the DisplayPort cables during installation?

Connect the USB 3.0 power cable first, then attach the DisplayPort 1.4 input and the three display outputs.

Will I need to replace the USB power cable if I move the hub to a system that only has USB 2.0 ports?

The hub will not operate on USB 2.0 because it cannot deliver sufficient power; a USB 3.0 port is mandatory.
