How Does A Video Wall Work?

A video wall is a great way to capture the attention of customer, employees, & students through a multimedia presentation.
  • Video Walls are a collection of display screens that are used to present a multimedia presentation.
  • Businesses, churches, schools, & advertising companies use video walls to communicate messages.
  • A great way to capture the attention of your intended audience is through a memorizing video wall.

Have you ever seen a screen so big that it made you ask, how did they do that? Video walls are an exciting way to display anything from a restaurant menu to a movie in a way that is sure to impress. The wow factor of huge video walls is undeniable, but they can also be extremely effective in other places like classrooms and board rooms. Video walls come in all shapes and sizes and actually take a considerable amount of technology to make the perfect image every time. In the end, they are an absolutely breathtaking way to display anything imaginable.

What Is A Video Wall

A video wall is not actually one screen but multiple screens all joined together to create one large image. The edges of the screen are minimized or even removed completely to allow for seamless connections between the panels. The great thing about using multiple conjoined panels is that each respective screen can show a unique video or they can all display one part of a huge video. There are many types of video walls from LCD monitors to the most popular technology: LED displays. Video walls provide a breathtaking image for any space that will leave your guests or customers speechless.

Components Of A Video Wall

Although a video wall may seem simple in concept, the execution requires many components to efficiently pull off. The display panels that present the image are the main technology that people will see. But there are also a host of computers behind the scenes that allow the panels to display the correct images.

Display Panels

A display panel is a surface that uses different light technologies to create an image or video. Televisions and computer monitors are two examples of very common display panels that are just about everywhere. Every display panel ultimately serves the same purpose: to function as a platform for viewing  a video or image. The technology and materials used to execute this is what differentiates all the types of display monitors. The classic methods used to create images is LCD or liquid crystal display technology. LCDs use a backlight, polarizers, color filters, and liquid crystal panels to create an image out of tiny red, green, and blue pixels. Some of the more modern displays use LED or light emitting diode technology. These displays use tiny bright lights to create stunning images with less power and more control and clarity. Besides flat, beveled displays like TVs, display panels also come in seamless tiles and even cubes for maximum customization.

Video Wall Controller

Video wall controllers are the brains that keep all of the images synced up across all of the screens. Controllers are typically computers with a lot of video processing power that allows you to input commands to control the video wall. There are three types of controllers available: OEM, PC-based, and professional-grade touchscreen controllers. OEM controllers are the default hardware that comes with the video walls. They are typically matrix switchers controlled by a remote. Another option is to hook everything up to a PC. Although this may be the most affordable option, it can lead to stability issues and is limited in its control options. Lastly, the professional-grade touchscreen controllers represent the best money can buy. They offer a host of features with an intuitive interface that makes them one of the best options overall.

Video Wall Processor

The video wall processor is the software that you interact with to set up your video wall. It is installed onto your chosen video wall controller and is responsible for making sure the right image gets sent to the right screen at the correct resolution. Video wall processors are installed onto a matrix switch and typically controlled with a remote. You can use simple processing software for video walls with one source of video being displayed onto multiple screens. However, a more advanced processor may be necessary for displaying content from more than one source.

Main Uses Of A Video Wall

Video walls don’t just look cool, they can also be used as a tool to drive business or impress customers. When placed in a high traffic area, video walls can be a great way to show a variety of content that will catch eyes and drive sales.


Imagine you have two ads, one is on a 40 inch LCD screen and the other is on a 10 foot video wall. Which one do you think is going to get more eyes? Times square is a perfect example of how advertising thrives when displayed on video walls. They offer extreme flexibility since the content can be changed in minutes. It also allows you to incorporate animation, video, and other elements into an ad that make it even more impactful.

Meeting Rooms

Conference calls and presentations can cause issues with both employees and clients when trying to read text on dimly lit screens or projectors, especially during an important meeting. Video walls offer the opportunity to create a large, easy to read surface to display powerpoints and videos on. The number of displays allow customers to display multiple things at once and the brightly lit screens are sure to keep everyone engaged.

Displaying Business Information

Many businesses have already started implementing new video wall technology and have seen a significant improvement in sales and customer knowledge of their products. Businesses like restaurants have seen a huge upside in replacing their static menus with video walls that can change daily with new prices or specials. Or maybe a bar wants to show the big game the way it should be seen, on a massive screen. Being able to display exciting videos, pictures, and animations can turn something static and less interesting into an invaluable marketing tool!


Another great place for video wall installations is in schools and colleges. Video walls can be placed in high traffic common areas like cafeterias, welcome centers, or student unions to display information about the school, as well as real time updates and event information. Video walls can also be installed in the classroom to aid in lectures. From smaller touchscreen displays to ones that span across entire rooms, you can use a video wall to make lectures more fun and eye-catching. Students are not going to want to fall asleep, while educators love the flexibility and endless possibilities that video walls provide in the classroom.

Wowing Customers

The Las Vegas Sphere took the world by storm when its giant, spherical LED video wall was switched on for the first time. Even smaller video walls with just a few screens present the opportunity to draw people in with a massive image sprawling across multiple screens. A video wall presents endless opportunities to wow and impress customers. The bigger the video wall, the less likely customers will be able to look away!

Benefits Of A Video Wall

Video walls can be used in a variety of ways and as we’ve already seen, they can provide many benefits as well. From simply wowing potential customers and drumming up buzz, to educating and informing students and employees in a unique way. There are so many ways that using a video wall can benefit you and your business.

Educate Customers

Educating customers on your products or services is a great way to get them to take that next step towards looking into your business or even making a purchase. You can use one or all of the compelling features of video screens to allow your customers to interact with your content. Imagine being able to display products across a huge screen and allowing customers to touch what color options, sizes, and pricing they want. The versatility and interactivity of video walls makes them a great tool for educating customers.

Employee Communications

In the professional world, things are seemingly changing every second of every day. What better way to keep up with the world than a video wall that can update multiple times every second? Video walls allow businesses to display important and up to date information to their employees in a way they can’t possibly miss. For example, companies can update their employees on new policies, upcoming events they don’t want to miss, and other important notices. Conveying this important information through an appealing video wall can improve morale and boost belief in the company. 

Gaining Public Attention

Video walls of all shapes and sizes can completely transform a space into a breathtaking one. Even something as simple as a two or three screen video wall can make a huge first impression on your target audience. Not only will you grab customers’ attention with impressive visuals, but you can establish a connection between the high quality graphics and your brand, product, or services. Placing video walls in high traffic areas will increase the amount of engagement you can garner, and is an extremely effective way to wow and impress an audience.
