How to Use a DisplayPort Multi-Stream Transport Hub

Tripp Lite’s DisplayPort Multi-Stream Transport Hubs distribute a single DisplayPort signal across multiple monitors – in mirror, extended, or video wall mode.

These hubs are compatible with DisplayPort 1.2, which supports multi-stream transport. To ensure full functionality, check your graphics card’s documentation and confirm that it supports the features you need. For example, some graphics cards—particularly older DisplayPort 1.1 models—are limited to mirror mode. Others support mirror and extended modes but not video wall mode. In this video, we’re using an AMD Radeon graphics card with AMD Eyefinity, a.k.a. “Video Wall”, technology.

I’m going to walk you through the process of connecting a hub to a source and four monitors, and then I’ll show you how to configure the monitors.

First, make sure the source is powered off.

Next, connect the source to the INPUT port on the hub. Then connect the external power supply and plug it into a power source. When the green LED lights up, you’ll know that the unit is receiving power.

Next, connect the four monitors to the four OUTPUT ports on the other side of the hub, then turn on the power to the source and connected monitors.

Now I’ll show you how to configure your monitors in the display settings for your graphics card. Mirror and extended modes can also be configured in the default display settings for your computer’s operating system, but video wall mode can only be configured in the settings for your graphics card.

Right click on your desktop and go into the settings for your graphics card. As I mentioned earlier, the graphics card in this example is an AMD card. Its settings can be found in the AMD Catalyst Control Center, which is up here at the top of this menu. You might have an Intel or NVidea graphics card. If so, just use the appropriate application.

As you can see here, each monitor is currently displaying the exact same thing as each of the other three. We’re in mirror mode, also known as duplicate mode. Monitors 2, 3 and 4 are acting as exact copies of monitor 1. To change the mode to extended, go into the properties for each individual monitor, one at a time.

First, extend monitor number 2. Click on the second monitor, select Extend in the dropdown menu that pops up, and follow the prompts to complete the process.

Now do the same thing for monitor 3, and then 4.

Once you’ve extended monitor 4, you’ll notice that the monitors are arranged in your control center side by side. If that’s not the way you have your monitors set up, you can move them around to match your setup. . . and that will tell your computer where you want your mouse to go when you move it from screen to screen.

And now you’re in extended mode. In this mode, the monitors are still acting as four separate monitors, but your workspace is extended and you can move things around from one screen to another.

To switch over to video wall mode and combine all four monitors so they act as one giant monitor, find the appropriate settings in your control center. Here in the AMD Catalyst Control Center, those settings are over here on the left, under AMD Eyefinity Multi-Display. Select Create Eyefinity Display Group, make sure your monitors are arranged how you want them to be arranged, click Next, and all four monitors will become one. Now anything you display on monitor 1 will be stretched evenly across all four monitors.

And now you have successfully configured your monitors into video wall mode.
