Video wall is an array of two or more screens that each display a 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 look at some of the solutions out there and how to set up Play for video walls and menu boards in general.
You can find more information on menu boards and video walls in our blog post.
Keep in mind the solutions below are just a few of the solutions on the market.
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 screens into a single unit on a driver level, so that Windows sees all screens as a single unit. You do not need a separate player when choosing the AMD Eyefinity solution.

Matrox has been doing video wall solutions for several years and in resent years great products for smaller menu-boards and video-walls and at an affordable price. Matrox QuadHead2Go is one of their out-of-the-box controllers that works great when building menu-boards and video-walls, the QuadHead2Go supports 4 screens connected through HDMI and makes it easy setting up a 1×4 or 2×2 menu-board and video-wall. In addition the QuadHead2Go is also available in a PCIe version controller. Using the QuadHead2Go or any other similar multi-monitor controller you will be needing a separate player.
Most large manufacturers, like Samsung, LG, etc. offers Daisy Chain in their professional product line. Daisy Chain means you can connect multiple screens through the screens HDMI ports. When connected you can set up almost any amount of screens into a super large video wall. Depending on brand, model, specification, etc. these screens support anything from 4 to unlimited screens. If Daisy Chain is your preferred solution you don’t need an additional controller, but you will be needing a separate player.
The software-based solution is something we’ve been seeing on the market more recently, we have not had the chance to test out all the providers on the market.
Userfull and other providers providing software-based solutions are cloud-based. This means your video walls are centrally managed and all configuration is made online. As you can imagine it’s not really possible to eliminate all the hardware when working with video walls, you need something to connect the screens and the cloud. In most cases you install a piece of software on the screen or add a small HDMI to Internet bridge – In both cases what you get is a communication bridge between the cloud and the screen.
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.
