Multi-Stream Transport: One DisplayPort Signal to Multiple Monitors

You have a DisplayPort 1.2-compatible graphics card with Multi-Stream Transport (MST) capabilities, and now you want to display the signal from your PC to multiple monitors. With the right accessory, this is a simple task.

A Multi-Stream Transport Hub allows you to distribute a single DisplayPort or Mini DisplayPort signal across multiple monitors. An MST Hub will have either a DisplayPort or a Mini DisplayPort connector; select the hub appropriate for the port on your computer or tablet.

An MST Hub allows the use of three different modes for multi-monitor displays: duplicating your primary display, extending your display across multiple monitors, or creating a video wall. Let's take a closer look at each of these display modes:

Duplicate Mode

Also called cloning or mirroring your display, in duplicate mode the same image will be displayed on each monitor. Duplicating a display is useful in settings such as retail environments with in-store product promotion screens; arrival and departure boards in airports, bus terminals and train stations; video presentations in classrooms, churches or auditoriums and multiple information booths and kiosks at trade shows. Duplicate mode is backward compatible with DisplayPort 1.1, so it can even be used with many older graphics cards.

Extended Desktop Mode

Extending your display allows you to show your PC's desktop on all of the connected monitors, while having a different window open on each monitor. The monitors still function as separate displays, but your usable workspace is extended and you can easily multitask and even move things around from one screen to another. You will be able to work on multiple documents at the same time, boosting your productivity. Extended mode is especially useful in presentations when you want to display notes or reference data on one screen while performing a demonstration or showing a video on another screen.

Video Wall Mode

Creating a video wall lets you combine all monitors in your setup so they act as one giant monitor. You can arrange the monitors however you want them: vertically, horizontally or clustered together. In video wall mode, the monitors will correctly display your content to create a dazzling, eye-catching presentation. Create a panoramic digital sign or wow the crowd at your next trade show. Three monitors aligned horizontally also make for a super-wide-screen gaming experience. A computer with a DisplayPort 1.2-compatible graphics card (such as AMD Radeon with AMD Eyefinity technology) is required to display in video wall mode.

Available for Many Types of Monitors

Tripp Lite has MST Hub solutions with built-in converters to support HDMI and DVI monitors, as well as DisplayPort monitors. You'll also need the compatible cables to connect the hub to your monitors; we recommend the following cables:

MST hubs are compatible with DisplayPort 1.2 standards, but to ensure full functionality, check your graphic card's documentation to confirm it supports the features you need. For example, some graphics cards - particularly older DisplayPort 1.1 models - are limited to the duplicate mode. Others support duplicate and extended modes, but not video wall mode. Finally, be aware Mac OS X does not support MST for NVIDIA and Intel Graphics Processor Units; you will be able to use the duplicate mode, but not extended or video wall modes.
