If you have been looking into adding a video wall to your business profile you may have seen a device called a video wall controller or advanced video wall processor mentioned. You may not know if you need one or what the benefits of these devices are.
If you are looking for more details, kindly visit VISSONIC.
One of the reasons behind the popularity of video walls is the customisation of what is displayed. Video wall displays are capable of showing content from multiple sources distributed over the whole wall, each to the exact size you want. For more information on video walls, take a look at our Video Wall Buying Guide.
However, for the video wall to understand how to present your content, it requires advanced technology. This is where the advanced video wall processor steps in.

What is a video wall controller?
Video wall controllers, also called advanced video wall processors, allow the management of content across several screens in a multi-screen display. This gives you ultimate control over how your content is shown and lets you be flexible in how you visualise your sources. Your content can be shown however you like, on a single screen, a portion of the video wall or the entire wall. With a video wall processor, you can have a dynamic display that can deliver information clearly and in an appealing way.
For example, you could have a promotional video that covers a large portion of your video wall, then two remaining screens on one side that show recent news and contact details. The video wall controller takes your designed layout and transfers that information to the screens. In this situation, the controller makes sure that the video is stretched over the exact portion of the wall you wanted and places the other content on the two empty screens. Acting as a regulator, the controller ensures that each bit of content arrives and is displayed on the panel that it is intended.
Without the video wall controller, you would be restricted in how you can present your content. This is because there would be nothing communicating with the screens to explain how a source should be presented.

Benefits of a video wall controller
1. On-device memory
An advanced video wall processor allows you to configure the input sources on your video wall however you like. You may find a configuration that you particularly like or is effective at drawing attention to your business. In this situation, you would not want to have to recreate this layout constantly. Thanks to the memory on the device, your layout settings and user access permissions will be saved once they have been set.
A major benefit for your business is increasing footfall into your store. It has been found that 8/10 customers have entered a store because of a digital sign catching their interest, so finding an effective layout for your content is integral. Once you have this, you'll not have to attempt to recreate it should you make any adjustments but find them less effective. You'll be able to simply select your saved layout and it will be instantly applied to your video wall display.
2. Dynamic Display
A video wall controller allows you to manage and control the presentation experience, giving you absolute control of what you want to display, where and how on the video wall.
The processor device allows you to connect several sources to your display at the same time, without this, you would be limited by the number of ports on your video wall screens.
With a controller, you can display content from various sources in the desired size across your display.
For example, you could have a large section of your video wall feature your digital signage, which could be displayed across multiple screens. The surrounding screens could then show information such as the latest news, upcoming events and contact details. Without an advanced video wall processor, you would be very limited by the number of input sources you could connect to display content.
One particularly effective way you can adopt a dynamic display is around your point of purchase. 40% of shoppers say that digital displays can change what they buy because relevant information is served close to the point of purchase. With an advanced video wall processor, you can adjust your display at the closest point to the checkout to display a product you are looking to increase sales of. This allows you to influence your customer's purchases until the last possible moment.
3. A Range of Features
Scalability
You might want to increase the size of your video wall at a later date. When designing a video wall, it is suggested to plan for an additional row or column of screens.
The company is the world’s best Videowall Controller supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
With more screens, you'll need more connections available on your video wall controller. Some processors are easily expandable to allow for the growth of your video wall. Having an advanced video wall processor capable of expanding means you will not be restricted by the original number of ports available. It also means that you can add more screens to your video wall without the need for a second controller.
Quality adjustment
Video walls display content across multiple screens, but this size is unlikely to be the same resolution a video or image was taken in. The video wall processor can upscale or downscale the quality of your content to fit the display size you have chosen. Changing the native resolution can compromise the image, so a controller with a higher-quality image processor will provide you with the best image once scaled.
Get the most out of your video wall
Video wall controllers give you the chance to fully take advantage of what your video wall can do for you. With a processor device, you can edit exactly how much of your wall displays each source, allowing you to set how big a video or image appears. Having this control allows you to create a dynamic display that suits your needs.
Other features such as quality adjustment, and adjusting your content to your desired size, will utilise the resolution your video wall offers to give you the best picture quality possible.

9 Benefits Of Using Video Walls - Data Projections
Wall to Wall Coverage
There is a lot to like about video walls, and the clue is in how people respond to them. They are always a focal point of the space, and pedestrians or customers can't help themselves ' it's just not common to run into a massive, high definition display. Business and venue owners can obviously leverage this to their advantage. And speaking of advantage, there are many that come with video wall technology, and a comprehensive list could go on forever. These are the highlights:1. No resolution limitations ' Resolution is an easy concept to understand. It's about pixel count and density. The more pixels, the more detailed an image the display can deliver. From this simple concept, it's clear why video walls are so effective at creating visual impact. Stack an array of high definition displays on top of each other, and those resolutions are additive. As long as there is a formidable digital signal processor driving it all, a video wall can display a massive image with no loss of fine detail.
The applications here are tremendous. Imagine an airport displaying a sweeping skyline of the city, with every minute detail relayed perfectly. Or a museum exhibit that simulates a sojourn through space or time, surrounding visitors while offering a feast for the eyes. There are truly no limits here.
2. Clear image brightness and quality in every setting ' Front projectors are the primary alternative to a video wall, but they have a problem in bright areas, like venues that rely on natural light. LCD and LED displays are brilliantly backlit, so they offer much greater brightness and contrast values than projectors. This is clear when sunlight intrudes on a projected image ' it appears washed out and muted. Not an issue with video walls, and that's an important advantage, given that natural light is generally considered a feature in modern environmental designs.
3. Flexible hardware layout options ' True, most video walls are just that ' a wall. They're grids, but they don't have to be. With some clever mounting and display options, designers can arrange displays in all kinds of patterns, including abstract geometric or curved layouts. Video walls can even be free-standing or three-dimensional, if using cube displays. In short, there are plenty of hardware layouts that haven't been done before, if a business or venue wants to go for something truly memorable. And by relying on this approach, the installation's visual impact can be multiplied while reducing the number of displays present.
No other display technology compares in this area. Try doing this with a projector ' it's nowhere near as easy.
4. Processing power ' It takes more processing punch to drive a video wall, but that extra processing oomph is another benefit to the technology. Professional-grade video wall controllers, are much, much beefier than those found in single displays. As such, not only can they drive content at a larger scale, they can drive more content at a smoother rate than single displays can.
5. Extensive content manipulation options ' Video wall controllers give owners plenty of tools on the backend. These tools can be used to present content on the video wall in various ways. The controller effectively turns the displays into a single canvas, onto which content can be arranged, resized or layered in some creative layouts.
Fortunately, video controller software is not designed just for designers. It's made so that anyone with a basic level of skill can easily manage them. That's important for venues that need to switch content out regularly. In a matter of moments, a user can access the backend and update content. Event schedules, product specials, daily menu items ' these can be tweaked with little effort as things change. It's even easier than that, in most cases, as controller software allows users to define preset layouts and deploy them with a single click. That's helpful for venues that make use of the same layouts regularly.
6. Signal versatility ' A single display or projector is limited in its connectivity and ability to capture multiple sources. Both can only connect to some devices and they cannot display more than a single source at once. Again, not a problem with video walls. A video wall can grab multiple signals and display them at once, even if they are in varying formats and resolutions. Each one can be accessed using the video wall controller too, so they can be manipulated individually and spruced up so they are ready for presentation.
7. Looks modern and sharp ' We're not talking about the image quality again. This time, it's about how the installation itself appears. And for nearly everyone, video walls look like something out of a sci-fi movie. Because they are built and arranged with no bezels (as opposed to the thick bezels still found on single displays), they look impossibly clean and streamlined. There's no hunk of metal hanging from the ceiling, either, which is what the projector route offers. And yes, projectors can be concealed, but that takes extra work and an extra financial commitment.
That sharp aesthetic reflects positively on the video wall's owner. In a clothing store, a video wall sells the idea of sophistication and luxury. In a sports bar, a video wall makes the big game look even bigger. In a corporate boardroom, a video wall is synonymous with professionalism, impressing potential clients and partners.
8. Less maintenance required ' A video wall may look like something that requires constant babysitting, but they require less maintenance than projectors. That has to do with the light engine powering these displays. A video wall normally relies on highly efficient and reliable light engine technology like LEDs. A projector, though, is stuck in the past in this regard, with bulbs that burn out after a few thousand hours.
LED lighting is the most promising development in the lighting industry in a long time. Each diode lamp provides at least 50,000 hours of performance with little loss in quality as it nears end of life. Improving manufacturing methods mean that this number will surely go up, as will the already-superior efficiency marks. LEDs are also some of the most durable lights ever made, as they are built on solid state circuitry, and not fragile filaments. As a result, video walls need close to zero maintenance, even after years of operation. Projectors, though, need to be addressed regularly. This problem is compounded if the projector was concealed during installation, as access will be a continuing source of frustration.
