Cygnett Hubs Compatibility Guide

11th, March 2025

Why buy a Cygnett USB-C Dock / Hub?

Cygnett USB-C docks / hubs are a powerful and versatile accessory for tech users offering a range of additional ports to your laptop or PC.

How can I identify if the USB-C port on my device can output video?

No icon: If no icon next to the USB-C port, this port may only transfer data or charge your device. For the exact specification, please refer to your device’s product specification manual.

Thunderbolt 3 or Thunderbolt 4 icon: If there is a symbol of a lightning bolt next to the USB-C port, a compatible dock / hub will support video output. DisplayPort hubs or docks will also work with this device.

DisplayPort icon: If there is a symbol of a D (DisplayPort) next to the USB-C port, a compatible dock / hub will support video output.

How many monitors can I connect to my Cygnett USB-C dock / hub?

The number of monitors you can connect depends on:
a) The type of Cygnett dock / hub you are using (if it has a single, dual or triple HDMI output).
b) Your device’s ability to output video via USB-C (if the port supports Thunderbolt or DisplayPort).
c) If your dock / hub is compatible with Thunderbolt or DisplayPort devices (list of compatible Cygnett hubs below).
d) How you intend to display your content, either mirroring or extending the main display (definition below).
e) If your device supports MST (Multi Stream Transport Mode) or SST (Single Stream Transport Mode) (definition below).

Mirror Mode: duplicates the devices screen onto all additional monitors connected to the dock / hub.

Extended Mode: All displays connected to the dock / hub can have unique content. Each screen can act as its own individual desktop.

MST (Multi Stream Transport Mode): the technology that allows multiple content streams to multiple external displays from a single device. MST can work in both Mirror or Extend mode.

• MST Mirror Mode Example: 1 compatible laptop connected to 2 external monitors; all 3 screens can display the same content.

• MST Extend Mode Example: 1 compatible laptop connected to 2 external monitors; all 3 screens can display unique content.

• SST (Single Stream Transport Mode): the technology allows one content stream to multiple displays from a single device. SST can work in both Mirror or Extend mode.

• SST Mirror Mode Example: 1 laptop connected to 2 external monitors; all 3 screens can display the same content.

• SST Extend Mode Example: 1 laptop connected to 2 external monitors; the laptop screen (A) can display unique content whilst the first external monitor (B) can display different content. The second external monitor (C) will duplicate the content shown on the first external monitor (B). Any additional monitors connected will duplicate the content shown on the first external monitor (B).
