Video Wall

Video walls

Video wall is an array of two or more displays that each display part of the content and together all the screens make up the full picture. There are several ways to set up a video wall, however in this article we’ll cover one of the most economical options using AMD Eyefinity software with Play Digital Signage.

AMD Eyefinity

AMD Eyefinity is part of AMD’s graphics card driver software suite (Catalyst Control Center). In order to use Eyefinity, you’ll need AMD graphics cards, so keep this in mind when choosing a player device for your video wall. This software merges displays into a single unit on a driver level, so that Windows sees all displays as a single unit.

Setting up

If you haven’t already, install AMD Graphics Drivers.

In this guide we’ll create a simple 2×1 video wall, however you can even use several AMD graphics cards. We’ll start out by connecting the displays to the computer, so this is how Windows detects them:

Windows detects 2 different displays



You can launch “AMD Catalyst Control Center” by right-clicking on the desktop and selecting the option from the context menu. On the left menu navigate to “Create Eyefinity Display Group”:

Select desired layout and press “Next”

Additional arrangement

You can re-arrange the layout

When you’re done, Windows should now see all your displays as a single unit:

Windows detects one wide display

Instead of 2 displays we now have a single virtual display that is twice the width

Designing content

Now that the display output of Windows is split into 2 sections by the graphics drivers, our application also treats it as a single display, so business as usual. In this case we joined 2 displays horizontally, so when creating content, your playlist aspect ratio should match the virtual display. So instead of the usual 16:9 aspect ratio, you should create a playlist with 32:9 aspect ratio (or use resolution 3840:1080 when creating a playlist). You can read more on creating playlists with custom aspect ratio in our display zones guide.


Can I simply use Extend mode?

In our Windows / Mac / Linux application settings you can resize the window to span across 2 screens, so it is also possible this way. However depending on the display brand, graphics drivers and operating system it can’t be guaranteed that the application will restore into correct position after a restart (thus we urge you to test several times that the application always launches over all extended monitors). Therefore using Eyefinity is more reliable as it bypasses Window management and scaling altogether.
