What is a video wall? Our video wall definition

In short, a video wall is a collection of screens that are combined/tiled together to create one large display. Typical display technologies used include LCD, direct LED tiles, rear-projection and laser displays. The purpose for using video walls varies depending on the industry. Industries where video walls can be used include; corporates, hospitals, retailers, government offices, churches, schools, casinos and hotel receptions.

Most video wall installations are going to be LED for a few reasons:

• no seams on the wall
• high brightness
• flexibility in design e.g. curved screens for stone column

Because of their size and clarity, video walls have a WOW factor that makes them very effective for marketing messages and branding. It&#;s important to note that the content displayed is key in reaching messaging goals for the video wall. And in order to optimize the content displayed, content management software is needed.

The software enables users to change the content, adjust the content layout, and update content schedules. It provides a richer set of control features including multi-user access and reporting.

That&#;s what this article is about i.e. video walls with content management software. Surprisingly, only 13% of the video wall systems installed have content management software. Such projects run the risk of showing poor content, which makes the video wall a very expensive decoration.

How does a video wall work?

A video wall is a collection of displays aligned so content can be displayed over the displays continuously. Video walls works by using a specific type of hardware setup to display content without interruption. This also requires software to help plan and configure the content.

Benefits of a video wall

But why should you even use a video wall? Below are the top benefits of a video wall.

• Grabs attention
• Employee time
• Different types of content simultaneously
• Suitable for a wide range of industries
• Flexible installation
• Support content customization
• Increase sales
• Improve customer experience
• Consumers prefer them

1. Grabs attention

Because of their large size, video displays are able to command attention. They are hard to ignore by customers, employees, or visitors, which makes them an ideal tool for an organization&#;s branding or informational campaigns.

2. Employee Time

Video walls can help perform tasks an employee normally would. It can free up employee time so they can work on more pressing tasks. This is done by displaying important information that staff would typically have to answer: For instance:

• Large malls can display maps on video display
• Parks and stadiums can display frequently asked questions
• Hospitals can display services offered online

3. Different Types of Content Simultaneously

A video wall that is powered by content management software is designed to display different types of content simultaneously. For instance, a campus can use a video wall to display maps, school events, and useful information like weather, news and social media.

4. Suitable for a wide range of industries

Traditionally, video walls, especially LED ones, have been used in retail for advertising and at events. Costs were high and content management wasn&#;t as evolved. Today, video walls are cheaper and more affordable for small and medium businesses. They are being installed in corporate offices, schools, government offices, hospitals, hotels, casinos and houses of worship. They are so diverse and thus are used across a large range of industries.

Check out our video wall examples post for some inspiration!

5. Installation is Flexible

LED video walls offer a lot of flexibility in design. For instance, they can be curved to fit around corners and columns. Additionally they can be shaped in architectural ways outside of the traditional rectangle or square install.

6. Support Content Customization

The content management software enables businesses to customize and personalize the content displayed on the screens.

Different content can be displayed at different times of the day e.g. a restaurant video wall can show different breakfast, lunch and dinner menus. The content also auto-updates e.g. when a calendar changes, the events listed on the video wall are updated.

7. Can Increase Sales

Retail businesses that use digital signage can improve their sales by 32%. Retailers can use a video display system to alert thousands of target customers about discounts and other great deals.

8. Can Improve the Customer Experience

An estimated wait time sign can combat customer dissatisfaction resulting from unpredictable waiting times. Leading service providers have been using this trick to keep clients waiting patiently. Thus, like those leading service providers, any business can use this system to improve their customer satisfaction scores.

9. Consumers prefer Shopping in stores with Video Displays

42% of consumers are likely to purchase from stores with video displays rather than those without. The video displays give customers more information about the products, help to upsell complementary products and overall improve the ambiance in the store.

Video wall system components

While the display is the most visible part of a video wall, it isn&#;t the only element. Several other video wall system components collaborate to display those attention-grabbing images on display.

Some of the components are:

Hardware

The hardware refers to all physical components that make up the entire system. The most significant hardware are:

• Digital display
• Media player

Digital display refers to the screens. For instance to form one large display, screens can be tiled together. The screens can be LED  or LCD. We recommend using commercial-grade screens with narrow bezels for seamless viewing and best content display.

LED screens have thinner bezels, the widest viewing angles, best picture quality, and more energy-efficient. They are however much more expensive than an LCD screen of the same size.

The media player is a device you connect to your screen. For example, the media player can be connected via an HDMI cable or VGA ports to the screen. It receives content from the software and displays it on the screen.

Software

Also known as the content management software (CMS), digital signage software is the central platform to allow users to manage their digital signage content.

Without going into too much detail, your software is the command center that lets you upload/create content and deploy it to your video wall. This is where you&#;ll manage the content displayed and the hardware used.

Content

This is undoubtedly the most essential aspect of a success digital display. It&#;s what the target viewers see and interact with.  This content can be in the form of images, screenshots, videos, infographics, GIFs, memes, and presentations.

Designing your content

Video walls display information. Ideally, this would be to the right target audience at the correct time. Otherwise, this communication and advertisement channel will be less effective.

So how does one make sure that their video wall system plays its role effectively? Below are some video wall content design tips:

• Use high-quality realistic images/videos
  • Like any visual, high-quality images and videos will easily command anyone&#;s attention than poor quality visuals. Even so, one should refrain from using heavily filtered pictures or videos.
• Keep text short and to the point
  • As a rule, any text on a display wall system should be as concise as possible. A single line should contain a maximum of 5 words. Anything above five words will look cluttered and harder to read. Also, texts should be large and colorful enough for anyone to read without straining.
• Use the right screen brightness
  • Lighting affects the visibility of the content displayed on the video wall&#;s digital screen. As an example, target viewers can hardly see content on a dim screen during a bright day. It&#;s important to adjust the screen&#;s brightness according to ambient light.
• Do not clutter the video wall
  • While a single video wall system can display multiple types of content, it isn&#;t advisable to stuff it. A professionally designed video wall should contain an adequate white space to let readers view or read through the content easily and quickly.
• Test content often
  • Testing content is the only way one can know if their content is appropriate, understandable, and actionable. Otherwise, your digital signage will not properly pass the desired message. To test your content, the content creator can run periodical surveys to gauge the content&#;s performance and impact. That way, content creators can discover and implement corrections to improve their ROI.

Video wall applications: what is a video wall used for?

Most savvy business owners first question when they see a video wall boils down to, &#;How can I use this technology?&#; The top video wall applications are:

Video wall installation: How to make a video wall

By far the most difficult aspect of the process is the video wall installation. For those looking for how to make a video wall, we have a great mini-guide below.

Video walls are a set of screens that work together to create one continuous and impressive display. You may want a video wall to relay information, create an immersive display, interact with your audience, or for presentations. They are difficult to create for those that are unfamiliar with the process. However, following the tips in this guide should make it easier.

1. Have a Clear Vision

You need to create a draft project document that highlights its important points, goals, or objectives. Some points to consider include:

• The purpose of the video wall, what you plan to display
• Location: is it near WiFi, internet cable, electrical outlet, near a water fountain?
• Size: the size that would accomplish what you want to achieve
• Layout: for instance, in a 4 TV video wall project, do you want that in 4×1 or 2×2 video wall layout?

2. Measure Everything

If you decide on a DIY video wall, you are likely to mess up the measurements. Here&#;s what you should include:

• Display size: people only consider the screen size but overlook display size. Measure the bezels and width
• Clearance: the space behind the display and support structure 
• Frames, supporting structure, walls 
• Distances: to power supply, internet connections, between displays
• Space allowance: for media players, internet or WiFi adapters
• Weight: consider supporting structures, cables, video wall controller 

3. Select Your Hardware

The most important digital signage hardware element is the video wall panels. If they are for digital signage, you want high-quality video wall displays like an LG or Samsung video wall. Using Samsung for illustrative purposes, a single display unit costs $2,000 to $6,000.

When choosing a video wall TV, remember that a thin bezel TV for video wall will look the best. They create an illusion of a seamless video wall, especially if you choose a multiple panel set-up, such as a 3×3 video wall. Another thing to consider is that LCDs are better at close-up viewing, and LEDs look better at further distances. 

Video wall mounts come in various types; make sure you get the right one for your displays. For instance, the Peerless video wall mount can only accommodate 46&#; to 55&#; video wall TVs. A simple Peerless 2×2 mounting kit for 46&#;-55&#; screens costs $534.

4. Consider Media Players 

Digital signage media players allow you to control and show content on digital signage displays. Most media players come bundled with video wall software free of charge.

If you have a simple project such as a 2×2 video wall mount, a simple $350 Mvix Core media player will do. For a bigger set-up like a video wall grid, you need more computing power. A desktop computer that has several display ports will be more suitable as your video wall processor. Alternatively, you can go with video/matrix players or video wall controllers. They are devices that allow streaming of a single video source to multiple screens.

It would help if you had digital signage software or content management software (CMS) to control and display content on your video wall. Although some software is cloud-based, you can choose an onsite solution such as Mvix software.

5. Create a Plan

Video wall signage is not cheap. Create a detailed project draft that lists down all materials before you start. Let others run through the draft to ensure you cover everything, preventing oversight that could prove costly down the road. 

You are likely to overlook some design features; why not create a wall schematic? The wall drawing will give you a rough idea of what the video wall will look like.  

6. Construct Your Wall

A grid-style video wall is the most complicated set-up as it requires a lot of configuring and installation.

1. Displays and mounting &#; match your screens to the right mounting and adjust according to the grid. Bigger set-ups will be bolted to the floor, smaller ones to the wall.
2. Accessibility &#; If you decide on an LCD or DIY LED video wall, leave some space for installing cables and media players.
3. Software installation &#; install and update the software and load it with content.
4. Audio &#; connect the media player to external speakers. Be mindful of the speaker placement to improve acoustics.

7. Customize Your Displays

With your digital signage video wall up and running, you need to create customized content for display. Before you do so, you need to develop digital signage content through research, content creation, and distribution. Some innovative digital signage content ideas of:

1. Live social media feeds
2. FAQs
3. Emergency, News, traffic, weather alerts
4. Quizzes and games
5. Motivational messages

Like any other electronic, you should regularly clean your video wall screens to get rid of dust and dirt. Ensure you update the software to keep it running smoothly. Support needs to check the displays to catch any degradation quickly and prevent downtime. Additionally, keep the video wall display off for at least two hours daily.

You need to keep your content fresh and interesting through updates. Fortunately, there are plenty of digital signage apps that simplify creating and updating rich content. 

Worth the Investment?

Are video walls worth the investment? The short answer is yes. When used, this technology can increase an organization&#;s brand identity and streamline visitor experience. A video wall system can foster good first impressions, support self-service, and free up employees. When video display signage are designed professionally, they tend to deliver the best benefits. Unlike amateurs, professionals will align the system for enhanced visibility, and set up the system appropriately. With an expert&#;s input, a video wall will not disappoint.

LED walls have become the first choice for large digital displays thanks to their versatility, durability and vibrant full-colour graphics (and the fact that they&#;re becoming more affordable!) &#; but what is an LED wall and how do they work?

In this guide we&#;ll look at a what an LED wall is by looking at the components that make them up &#; so, LED tiles, cabinets, frameworks, media players and controllers.

We&#;ll explain how LED walls work, and what the pros and cons of using one are.

We&#;ll also clear up that all too common &#;LED screen vs. LED wall&#; and &#;LED wall vs LED video wall&#; confusion.

What is an LED wall?

Whilst an LED wall may look fairly simple, they&#;re made up of lots of different pieces of hardware. They contain five different types of components (excluding cabling) which are:

LED tiles and cabinets

The part of an LED wall that you can see is a series of lots of small tiles with LEDS (light-emitting diodes) embedded within them. They all clip together to create a seamless space for displaying your content.

The tiles are slotted into a special container called a cabinet to secure them into place. These cabinets are square or rectangular (usually minimum of 50cm²) and generally fit four, six or eight LED tiles within one cabinet (NB: LED tiles are usually sold as part of a complete cabinet, rather than individually).

Once the tiles are embedded within a cabinet they are then mounted onto an LED wall framework (we&#;ll come onto those shortly).

Most LED tiles and cabinets are designed to be easy to remove from the LED wall display so that, should any tiles or cabinets develop a fault, they can easily be removed and replaced.

LED wall framework

LED wall displays need to have a very consistent surface. Any small lumps or bumps on a wall&#;s surface will create inconsistencies that are very obvious when the display is switched on. So, a separate framework is usually used to securely position the cabinets into place on top of and alongside each other, creating a uniformly smooth surface.

An LED wall framework is a modular system that slots together (like a Meccano set) so they can be made in whatever dimensions you want and can be wall or floor-mounted. In addition to creating uniformity across the display, frameworks will also make the LED wall more robust and easier to service. (NB: Some LED tile/cabinet manufacturers say that some led tile products can be affixed directly to a wall without a framework, we definitely wouldn&#;t recommend doing this!)

Although frameworks must provide a consistent surface, that surface doesn&#;t necessarily have to be flat. This allows curved LED walls to be created by placing LED tiles on a curved framework. However, this is a very complex (and fiddly!) task and should only be attempted by experienced installers.

Media player

A media player is a small but powerful computer which is used to run your content management software and communicates with your LED wall controller, instructing it what to show. Usually you only need one media player per LED wall display.

LED wall controllers

LED wall controllers act like a translator between your media player computer and your LED wall display. They are used to convert data from your content management software into a format that the LED wall&#;s circuitry can understand.

Each controller can process data for a set number of pixels within a display. This means that large LED wall displays with a high resolution will need more than one processor.

How LED walls work

LED walls work in a similar way to a traditional television set, with each diode representing a single pixel. By controlling the RGB colour of these pixels, and viewing the display from a suitable distance, you can view the content. By changing the diodes&#; colour several times a second (or switching it on and off), full-motion animation can be achieved.

This is all thanks to the LED wall controller, which transmits the data needed to constantly update each LED&#;s colour value (and on/off status) and change the image or video frame accordingly.

As with a TV screen, if you view an LED wall close up, you can see all the individual pixels that make up the images that you see, but view it from a distance and the pixels merge together to become a single coherent image.

Resolution

With modern TV screens, you can choose the resolution you want (i.e. &#;Standard Definition&#;, &#;High Definition&#;, &#;Ultra-High Definition&#;). With LED wall displays, you have even more choice.

You can choose how closely spaced the diodes are in the display which changes the resolution and therefore how clearly defined the images shown are.

The measure of how densely packed the LEDs on a tile are, is called pixel pitch. It is refers to the gap between each pixel and affects how close up you can view the display, without seeing it as individual dots.

A lower pixel pitch means you can see the image from close range. With a higher pixel pitch, your viewing distance needs to be further away. A good rule of thumb is to take the minimum desired viewing distance and divide it by 1,000 to get the ideal pixel pitch. So, for an LED wall that will only be viewed from at least five metres away (5,000 mm), an LED pixel pitch of 5mm should be sufficient.

Pixel pitch is also important because the cost of a cabinet is determined by the number of diodes within it. This is because LEDs are relatively expensive in large quantities. For a large display that won&#;t be viewed at close range, you can use tiles with fewer LEDs which will cost less than those tightly packed with LEDs. However, if your display will be seen by people at a range of viewing distances, or if clarity is important, you&#;ll need to use a lower pixel pitch for your display which will be more expensive.

Why use an LED Wall?

So, what are LED walls used for? There&#;s a good reason these vivid displays are used for prestige locations like Times Square, Leicester Square and Piccadilly Circus. We&#;ll explain why here.

Key advantages of LED walls

The most obvious benefit is that they&#;re very vivid. This makes them stand out &#; even against other digital displays &#; and they&#;re easy to see from a distance. Furthermore, they don&#;t have bezels so they offer a seamless display, unlike a traditional video wall.

They don&#;t have a glass screen over the display, so they don&#;t suffer from glare from the sun or other light sources. This means that, unlike projectors and traditional video walls, they can be used outdoors and in very bright spaces and still be very easy to see (they&#;re even more vivid than high bright screens which are designed to be easily visible even in full sunlight).

Because they don&#;t have a set size or dimension and don&#;t have to be flat, they&#;re very flexible and can be used almost anywhere.

LED walls are made using lots of component parts, all of which (apart from the framework) are easy to replace, which means that once purchased and installed, maintaining them is fairly easy and cost effective. LED walls will generally last twice as long as a screen or projector.

Key disadvantages of LED walls

LED walls have several advantages over other large displays like video walls and projectors, and only one main key disadvantage which is the initial hardware purchase cost, though they are becoming more affordable as time goes on.

Whilst they are relatively energy efficient (compared to a standard, commercial digital signage screen of a similar size), they are still fairly power-hungry. The cost of running a large LED on an ongoing basis needs to be factored in.

Clearing up some confusion

LED screen vs. LED wall

There is a lot of confusion between whether an &#;LED screen&#; and an &#;LED wall&#; are the same thing. As the technology is still relatively new, different people within the industry refer to them using different names, which unfortunately adds to this confusion.

When we talk about an LED screen, we generally mean an all-in-one television-like display which is a type of LCD screen. The maximum size you can get for an LED screen (at the time of writing) is 110 inches (measured across the diagonal).

As we&#;ve already explained above, an LED wall (also often called a &#;dvLED&#; or &#;LED video wall&#;) is made up of lots of different pieces of hardware. It has no set dimensions or sizes so it&#;s generally measured in square feet or square metres. The largest LED wall display in existence (at the time of writing) is 130,000 sq ft. However, an LED wall display could be as small as 1 square metre.

LED video wall vs. LED wall

As we&#;ve said, different people use different terminology in the digital signage and AV industry, and this context is probably the most confusing.

Most people have heard of the term &#;video wall&#; and understand it to mean a large digital display. As a result, some people refer to LED walls as LED video walls.

However, you can also have a video wall which made using LED screens, and these can often be called an &#;LED video wall&#; for short.

At Saturn, we try to avoid using the term &#;LED video wall&#; for this exact reason because it could refer to either type of display.

Generally speaking, if you use the term &#;LED wall&#; or &#;video wall using LED screens&#;, everyone should have a correct understanding of which type of display you&#;re referring to.

Potential pitfalls when buying/installing LED walls

LED walls are a compelling business choice thanks to their vibrancy, longevity and versatility, and they&#;re rapidly becoming more popular because of the various advantages mentioned above. However, there are pitfalls to be aware of when considering buying or hiring one.

The quality of LED tiles isn&#;t uniform, so the old adage of &#;buy cheap, you buy twice&#; very much applies. Cheaper tiles are usually made with poor quality diodes which can result in inconsistent colours. So, if you were expecting to see a consistent red colour right across your display, it may appear pink-ish, purple-ish or orange-ish in different sections of your display. They&#;re also more likely to fail after a short period of time (which will leave your display looking patchy) so the tiles will need replacing. For the above reasons, always try to purchase your LED tiles from reputable manufacturers (e.g. LG, Absen, Hikvision).

As we&#;ve explained above, an LED wall involves lots and lots of different pieces of hardware being connected up, which is a pretty fiddly business. Subsequently it involves lots of time to complete. However, its likely to take much longer if it&#;s done by an inexperienced installer, which will delay the project&#;s completion and potentially cost more than initially quoted. And if it&#;s done badly, the whole thing could need to be taken apart and reinstalled. For these reasons we would always recommend using a reputable installer with plenty of experience with LED walls.
