What is Video Wall Controller and How Does it Works?

We’ve all heard about how great video walls are but do we understand how they work? We¬†can tell you right now that it isn’t by magic. In actuality, video walls are controlled by a video wall controller, which is a brilliant piece of technology.

If you’re an AV specialist with a lot of expertise, you’re probably aware of a video wall controller. If you’re a mortal who still can’t figure out how to connect a printer to your smartphone, don’t worry; you’re in good hands.

This post will go over what a video wall controller is, why you might need one, where you might use one, and how to pick the best one for your AV project.

So please sit back and relax as we take you on a journey through the world of video walls.


Working of Video Wall Controller

Let’s briefly look at what video wall controllers do before we get too far into them. A video wall is a group of screens used to show one or more coherent images. A video wall’s resolution is determined by the sum of each monitor’s screen quality and can be used to display a variety of still or moving images.

If you’re concerned about space, don’t be. Video walls come in various sizes and are entirely customizable by the user. They can be 2×2, 3×3, 4×4, 6×2, 8×2, or any other configuration, so you have a lot of alternatives.

This system is also available in various forms and sizes, as well as a variety of price points, so you may select the product that best meets your needs. Here’s a quick rundown:

LCD: LCDs are a terrific option for those of us on a budget who need a video wall fix. Multiple LCD panels are used to create these walls, which provide a relatively high-quality display. Keep an eye out for any thin bezels that may interrupt your presentation; however, most high-quality controllers will be able to compensate for this.

Rear-projected cubes: This video wall is usually quite massive and gives consumers the feeling of being at a music festival. This system is high-performance, very reliable, and ideally suited for control rooms with time-sensitive objectives due to the integrated nature of rear-projected cube walls.

LED: You may have walked past a few LED walls without realizing it. LED lights project a high-quality and bright image on these screens. Consider places like Times Square, which has massive billboards that light up the night sky. These LED walls are excellent examples.

What is the Purpose of a Video Wall Controller?

Let’s dive into the meat of the matter now that we’ve covered the fundamentals. A video wall controller is a piece of hardware that processes all of the video wall system’s input signals. A video wall controller, in essence, is the brain of a video wall, allowing users to assign functions to specific screens.

These controllers handle data from sources that allow users to show various content types on a single wall. They divided and scaled an image to fit across a huge Windows desktop where image and live video merged.

As video sources, controllers can process HDMI, SDI, and DVI signals. Thus they’re pretty versatile. They’re usually highly adaptable and appropriate for most intermediate-level audiovisual projects.

Do you require a visual aid? It’s no problem. If you want to go extra technical, DEXON’s whole range of video display controllers with comprehensive specifications and more explanation is a must-see.


When AV aficionados wish to boost the speed and variety of their video wall, they usually need a video wall controller.

A video wall controller is a good investment if you suddenly feel compelled to include several sources in your video wall display.

Video wall controllers are beneficial for improving the performance of a simple and inexpensive video wall. Previously, saving money on displays meant sacrificing video quality owing to bad graphics, slow speeds, and big bezels, but this is no longer the case with a video wall controller. Wide bezels can be mitigated by video wall controllers resizing the image to match the space, reducing the impact of significant gaps.

High-performance controllers also allow us to increase the graphics and speed on low-resolution monitors, allowing you to receive high-production-value at a fraction of the cost.

Where May a Video Wall Controller be Used?

Here’s a rundown of where a video wall controller can be used:

Control rooms that are crucial to the mission

There’s no room for error in an AV system in mission-critical control rooms, requiring efficiency and minimal hassle. If a video wall is used to display essential information to a large group of people, users must be able to rely on it to work at all times. That’s where video wall controllers come into play.

With software that can accommodate numerous users, video wall controllers improve a video wall’s efficiency and general reliability. Command posts for the police

Video walls are highly effective for keeping track of cases and transmitting critical information to many police personnel. Officers can instantly share information from numerous screens using a video wall controller, allowing them to pick up the necessary information and head to a case. This is accomplished by combining signals from many sources and controlling the required screen size.

Configurations for transportation

We know video wall controllers are lovely at managing enormous amounts of data and transmitting it to a single source, making them ideal for confusing hubs like transportation terminals. Consider a train station: we’ve all experienced the frustration of looking for the correct screen to display your train platform and time; however, this can be a thing of the past with a video wall controller.

We can display all information from a single video wall thanks to video wall controllers’ ability to interpret data from many sources. This means no more scrambling for the proper screen and more time to rest and relax.

What Factors Should You Consider While Selecting?

The key to selecting the best video wall controller is considering your users’ needs. If your project is mission-critical and requires high-performance value, you should invest in a video wall controller with advanced software that can accommodate numerous users and alternative sources.

One of the best things about video wall technology is that customers may choose what they want to buy based on their technical skills and project requirements, so there’s no need to buy.

That’s all there is to it. We hope we’ve answered all of your burning questions about video walls. Check out DEXON Systems’ website to learn more about our product line and how we can help you change your AV project right now!
