Mirror or Extend your Desktop Over 3 Displays

The Accell Mini DisplayPort 1.2 to 3 DisplayPort Multi-Display MST Hub allows you to enjoy up to 3 DisplayPort monitors from a single Mini DisplayPort output. Available in DisplayPort and Mini DisplayPort versions, these hubs utilize the new multi-stream transport (MST) protocol, supporting up to 3 displays independently at 2048x1536 @ 60Hz each with DP 1.2 or 2560x1600 @ 60Hz in clone mode with DP 1.1 single-stream transport (SST). The Mini DisplayPort to 2 DisplayPort version of this hub was presented with the CES Innovation Award for Outstanding Design and Engineering.

View a Single Image Across Three Displays

You can chose to view a single image across three displays, perfect for gaming, graphics design or spreadsheet analysis. Easily dedicate each display to a separate application, providing the efficiency and productivity of multi-tasking. Use 2 Multi-Display Hubs for a video card with multiple DisplayPort outputs. Perfect for use in digital signage applications or to create a video wall.

*The maximum number of displays that can be enabled at the same time is limited by the number of Display Pipes supported by your video card.

Important Notes:

  • Testing has found a lack of compatibility with some systems when converting using DVI or HDMI adapters. Recommended for use with DisplayPort monitors
  • For optimum compatibility, Accell brand DisplayPort adapters should be used when adapting any of the video outputs to HDMI, DVI or VGA.
  • The Microsoft Surface 3 has a Mini DisplayPort output that can drive just 1 external monitor. This provides no application for using an MST Hub.
  • To adapt a Surface 3 to a non-DisplayPort monitor, please see our adapters. To connect to a DisplayPort monitor, use an Accell VESA certified, HBR2 rated cable found here.
