GUEST OPINION: Video walls are at the cutting edge of information technology and communication and have truly revolutionized the audiovisual industry, but how much do you know about them? Are you aware of the most important steps to choosing a video wall? If you’re scratching your head about either of these questions, you’ve come to the right place. 

At DEXON Systems, we ensure that our customers have access to all the information they need before investing in a video wall, so that’s why we’ve compiled this guide to choosing video walls so you can feel confident in your purchase. 

This article discusses what video walls are, some reasons why video walls are beneficial and the four most important steps to choosing a video wall for your AV project. 

Before we get into the specifics of choosing a video wall, let’s go over some basics for anyone who isn’t totally aware of what a video wall is. A video wall is a screen made up of individual monitors that perform in unison to display one or multiple images. Users can display images or videos of any size regardless of the monitor borders, meaning that you can facilitate a cinematic experience with a video wall. 

Video walls differ in size, typically starting from 4x4, and ranging all the way to 144x72 in arrangement. This means that this technology is super versatile and allows you to customize your experience around your project needs. In terms of quality, a video wall's resolution is made of the sum total of the individual screen’s resolution. 

Video walls don’t just operate by magic, they use a list of sophisticated technology that allows the user to arrange images and footage, mitigate harsh bezels and stream content from multiple different inputs. Here is a quick guide to video wall technology: 

Controllers: A multi display video wall controller is a computer chassis that handles different input and output signals from HDMI, DVI and SDI inputs. 

Processors: A video wall processor is the brains behind the project and allows the user to have full control of their project. This control box transforms input signals into viewable content and allows the user to control which screen they view the content on. 

Switchers: Matrix switchers are an all-in-one system that provides switching of different input signals, signal scaling, format conversion and much more. These are great for video wall projects of all sizes. 

Now that we have the basics out of the way, let’s discuss why video walls are so beneficial. Here are four reasons why you should invest in video wall technology today: 

Video walls are revolutionizing how we interact and distribute information in a working environment. This technology boosts engagement by providing a single means of information distribution, meaning that relying on everyone reading their emails for a big company announcement is a thing of the past. Higher engagement is also beneficial for several other environments, such as trade shows, education settings and mission-critical control rooms. 

Video walls can help you meet your key business targets by impressing your stakeholders and business partners. With a video

wall, you demonstrate that your business takes communication and the efficient distribution of information seriously. These are key qualities that help a business reach its goals. 

Traditionally, word of mouth and hearsay have dictated working environments, but no more. With a video wall, you can centralize your information distribution and provide one clear platform to communicate key announcements, distribute work and provide live updates on your business. This helps to create clear channels of information and rids your business of the plagues of miscommunication. 

Arguably one of the best parts of video walls is that the user isn’t restricted when using a video wall. This technology presents users with a myriad of different options, ranging from purely business and communication activities to entertainment. Video walls are truly defined by the user, so it’s important to remember that your opportunities are endless before you invest. 

So, now you know why you should invest in a video wall, let’s discuss how you should do this. Here are the most important steps to choosing a video wall for your AV project: 

One of, if not the most important steps to choosing your video walls is ensuring that the technology you choose fits your project needs. No two projects are the same, with each having different goals, audience sizes, time of use and much more. 

Before you take out your wallet to buy a video wall, you need to consider what your project needs. Ask yourself some of these questions: 

“How many people will see my project?” 

“Where will the video wall be used?” 

“Do I need this for business or entertainment purposes?” 

“Is my video wall necessary for a mission-critical environment?” 

This will help you gain a better understanding of your project needs and help you decide which technology is best. To help you do this, our products at Dexon come with an applications area guide that tells you which technology is best for which use. 

Depending on your project needs, the size of your video wall will differ significantly. If you’re using a video wall at a trade show or business conference, for example, it's likely you will need a video wall that can display content for large numbers of people. 

Therefore, you will need a video wall size that can accommodate this. The size of your video wall can dictate the price, so ensure that you find a size that fits your needs alone. 

Of course, nothing is free in the world and video walls have the potential to cost you a lot of money. Your budget is likely to dictate the type of video wall you buy, as each type comes with their own price range. 

LCD panels tend to be the most cost-efficient upfront but may experience interruptions in display quality and higher operating costs due to energy consumption. So, let your budget guide you, but remember that video walls are an investment and are certainly worth it. 

While we might all think of ourselves as AV wizards, it’s important to let our user abilities dictate the technology we use with

video walls. If you’re not a confident AV operator, then consider scaling your AV technology back, focusing on the bare minimum. 

This will optimize your experience, allowing you to have full control over your video wall. There’s nothing worse than investing in expensive technology and experiencing low quality due to human error, so consider adapting your selection based on your user ability. 

There you have it! Your comprehensive guide to choosing a video wall.
