Accell Mini DisplayPort 1.2 to 3 HDMI Multi-Display MST Hub

Easily Extend or Expand Your Desktop

The Accell UltraAV Mini DisplayPort 1.2 to 3 HDMI Multi-Display MST Hub allows you to enjoy up to three independent HDMI monitors from a single Mini DisplayPort output while utilizing the new multi-stream transport (MST) protocol.

Supports up to 3 Displays Independently

The MST Hub can support up to three high-resolution displays independently, two monitors with resolutions up to 1920x1080 @ 60Hz and the third monitor up to 2560x1600 @ 60Hz*. With the UltraAV MST Hub you can chose to expand a single image across three displays, perfect for high resolution gaming. For the efficiency and productivity of multi-tasking, easily dedicate each display to a separate application.

*The maximum resolution is dependent on the throughput of DP 1.2 or HDMI 1.4 as well as the graphics and display solution used.

For a digital signage or video wall application, use two MST Hubs with a video card that supports multiple Mini DisplayPort outputs. This setup will provide enough video ports to support up to 6 monitors independently. The use of multiple MST Hubs requires a computer and a graphics system with enough display pipes to support the multi-display array.
