Video walls are at the current edge of information technology and have truly revolutionized the way we distribute information and communicate in our offices, stadiums and even our homes. But what is a video wall and how do they work? 

Well, we’re here to answer all your burning questions about all things video walls. At DEXON, we know how important it is that you get all the facts straight before you invest in any kind of technology, so that’s what we’re going to do! 

In this article, we discuss what video walls are, where we can use them, how a video wall system operates, and some of the many benefits of a video wall. 

So, if you’re a total tech expert, or you have absolutely no idea what we’re talking about but still want to find out more, you’re in the right place. 


What is a video wall? 

Before we get into the nitty-gritty of video wall systems, let’s get some facts straight. Video walls are a collection of monitors that work together to display one or multiple coherent images where the resolution is the sum total of the individual monitors quality. What this means is that walls consist of lots of screens that can either isolate snippets of information or can transform your wall into a home theater. 

We know, it sounds like magic, but it’s actually pretty simple and you’ve probably even seen a few before. Cast your mind back to the last time you were in a train station. Do you remember seeing a large screen with multiple panels displaying all the different platforms and train times but seemingly working independently? Well, that’s a great example of a video wall! 

Multi screen control systems are really important as well, they make video walls work the way they need to work.
Where can we use video walls? 

The best part of video walls is that anywhere that the flow of information can be optimized or streamlined to lots of people, we can use a video wall. The use of a video wall is also an entirely subjective experience, so you don’t need to fit into the following categories to use one. 

However, there are some environments that really benefit from using video walls. Here are a few: 


Anyone who has ever worked in an office environment will tell you that a case of miscommunication can cause chaos. Offices are a hub of miscommunication, with so many of us relying on different screens, tabs and word of mouth for our important information. We also have to consider that not everyone is available for meetings all the time, so information can get lost pretty easily. 

With video walls, information can be streamed to everyone from a single source, meaning that everyone receives the same information at the exact same time. The best part is, this can be left up for a long time, so if someone is in a meeting, it’s no big deal because they can see the latest company update on the video wall when they’re done. 

Sports stadiums 

Ever sat in a sports stadium and seen a huge screen streaming all the action from the pitch, just with cool effects and in much better quality? Well, you’ve witnessed a video wall! Sports stadiums and entertainment venues are the perfect places for video walls because they provide an inclusive experience to all attendees. 

This means that regardless of whether you’re sitting courtside, or you’re way up in the nosebleed seats, you can see all the drama and action from below. 


We know how important security is to everyone, because who doesn’t like to feel one step ahead of crime at all times. We also

know the anxiety of feeling like you can’t have your eyes in all places at once. Well, you can stop panicking, because, with video walls, you now can! Video wall systems can connect to your home or office security cameras through a controller to stream all footage on your video wall

Because you can isolate specific monitors, you can display footage from every camera in your arsenal from your very own mission control room. Not only does this look like something out of a spy movie, but it’s also great for peace of mind! 

How does a video wall system work? 

Now that we’ve gotten the important stuff out the way, let’s get down to how this miraculous bit of kit works. 

In simple terms, video walls operate by utilizing sophisticated kits known as video wall controllers and matrixes. Video wall controllers and matrix switchers refer to technology that process input signals to display content on monitors. They essentially act as the organizers and enable the user to isolate screens, create effects and stream web-based content. 

The actual wall can come in different styles too. Let’s go through them: 

LCD screens 

LCD screens are probably the most popular option for video walls as up front, they’re pretty cost effective. They consist of LCD panels that come together to form a relatively seamless display. However, because of the nature of LCD screens, there is some interruption due to wide borders that surround each monitor. If this doesn’t bother you then go ahead! 

LCD screens are also pretty energy inefficient, requiring more power to keep things running smoothly, making them costly over time. 

Rear projected cubes 

Rear projected cubes are the best option for those of you that want to get that music festival standard of video walls. Rear projected cubes are the best for super demanding projects, made up of small cubes to present a high quality and super-fast picture around the clock. These may be best for control rooms in critical sectors where reliability and performance matter most! 

LED walls 

LED walls are the best for a super bright, high-quality display. These walls consist of LED lights to present an all-round better quality that is best for still images or advertisements. Shop windows and museums get the most out of LED walls for their super fast speed and crystal clear images! 

What are the benefits of video walls? 

Here’s a quick guide to some of the main benefits of a video wall: 

Increased engagement 

Video walls are a spectacle to look at, meaning that you’re naturally going to have more engagement just because of how it looks. But video walls increase engagement by diminishing miscommunication, helping people feel more motivated and less frustrated at work. 

With increased engagement, you can stay focused on what really matters, instead of answering the same questions about the big meeting several times. 


Let’s be honest, it’s pretty cool to have a wall of screens. It’s not shallow to admit it either. Having an impressive office can help you achieve your key business development goals, as video walls place you at the forefront of communications technology, meaning that clients and potential investors are bound to be awestruck by your business. 


Perhaps the very best part of video wall technology is that it’s an entirely customizable process. What do we mean by that? Well, it means that you and your users define the type of video wall technology you need to invest in, meaning that if your project isn’t super sophisticated, there’s no need to drain your wallet on expensive kit.
