video wall technology

Video walls have become a dominant feature in many businesses, industries, and entertainment settings in the last few years, mainly due to their versatility. But how do video walls work? Does it all just happen by accident? If you’re not sure of the answer to either of those questions, you’ve come to the right place.

At DEXON Systems, we ensure that our customers understand all aspects of the products they’re interested in before they invest. So, we’ve compiled this in-depth guide to video wall technology.

Today, we’ll discuss what video wall technology is, where we use it, what equipment goes into its operation and how they all work, and some of its many benefits.

Let’s go!

What is a video wall?

Let’s first discuss what a video wall is. A video wall is a collection of monitors used as a coherent wall used to display one or multiple coherent images. There are typically three types of video walls famous within the AV industry.

These are LCD panels, rear-projected cube-based walls, and LED walls. These walls can vary in size, versatility, quality, and price, depending on the type. Video walls typically come in sizes 2×2, 4×4, 6×2,4×2 and up to 144×72.

Depending on the use, you can use video walls to stream images and footage across one large screen or use them to convey multiple snippets of information. This is done by isolating monitors to display specific input signals. With the help of controllers, processors, and modular matrix routers, users have total control over their video wall experience.

Where do we use video walls?

One of the best parts about video walls is that there is no set environment for users to deploy them. There are several settings where video walls are wholly beneficial. Suppose you’re a business owner, for example.

In that case, you can use a video wall to improve your communication and information distribution, allowing you to create one unified space for important announcements and decreasing the impact of miscommunication or hearsay.

Alternatively, you can use video walls for demanding AV projects such as control rooms in emergency settings, surveillance, transport, and policing environments that require 24/7 operation with seamless information distribution.

However, the opportunities to use video walls are genuinely limitless; here are some other places you can use video walls:

What equipment goes into video wall operation, and how do they work?

So how exactly does video wall technology work? It isn’t an accident, and there certainly is a lot of complex and sophisticated technology behind video wall operation. Don’t worry; we’ve clarified some of the technology behind video walls, so you know strictly what to look for when visiting our product family at DEXON. Here are three technologies behind video wall operation:

Video wall processors

Video wall processors are a kind of control box that processes input signals and translates them to displayable content for your video wall—these work by transporting signals from several sources such as media players and satellites via a HDMI cable.

With this control box, users can perform several functions such as mapping content, scaling up and down, and improving

resolution. These are a must for any demanding video wall project!

Video wall controllers

Like processors, video wall controllers are a computer chassis capable of processing multiple input and output signals. This controller processes signals from HDMI, DVI, SDI, and video sources, allowing it to display different content.

Users can again perform several tasks with a video wall controller, such as managing layout, running a video wall locally, or via a remote network after installing DXWallControl on a PC with Windows 10 and overlay windows. Video wall controllers allow users to simply drag and drop their content onto the desired monitor.

Matrix switchers

Matrix switchers are all-in-one processors that allow users to seamlessly switch from one input signal to another with total ease. Suitable for any size AV project, matrix switchers enable functions such as signal scaling, frame rate conversion, output cropping, and On-screen display. One of the best parts of this technology is that it performs all of these tasks from a single box, so you don’t need to worry about cluttering up your workspace. Users can again run locally and remotely, requiring the help of a web-based browser and graphics user interface.

What are the benefits of video walls?

In case you’re not entirely sold on the idea of a video wall just yet, we’ve explained some benefits of video wall technology and how they can be advantageous to you and your business:


Improving a company profile is a never-ending battle for a successful business, so what better way to do it than by placing yourself at the forefront of information technology. With an impressive video wall setup, you’ll appear as one-step ahead of your competitors and prove to potential business partners and investors that you take communication seriously.

Better communication

Communication is crucial in a workspace, but we all know that it sometimes doesn’t come easily and can even get in the way of our productivity. This is typically miscommunication, messages getting lost in translation, and announcements coming from multiple sources.

With a video wall, users can have more control over their communication strategy by having one clear and concise method of conveying information. Video walls offer all the information distribution you need from one source, meaning that everyone receives exactly the same information in the same format. Gone are the days of hearing through the grapevine!


The multi-use nature of video walls means that users aren’t confined to a single operation. For example, suppose you need to stream web-based content while releasing your critical company announcements and essential information in an office space. In that case, you can do both with a video wall. By sectioning off monitors, video walls allow you to condense information into one area, multi-task and complete your essential tasks faster than conventional communication.


As businesses scale up, they sometimes grow out of their old strategies. To accommodate more sophisticated operations, they must invest in new, more extensive, and more expensive processes. Well, you needn’t worry about this with a video wall. Video walls are easily scalable, meaning that you can make them as big or as small as you like. With a video wall, your communication and information strategy grows with you, not against you.

That concludes our guide to how video wall technology works!
