The final considerations

What are video walls?

A video wall is a collection of screens that have been tiled together to form one large display. This can then be used to present content such as videos, images or even different types of data.

The number of screens brought together can vary depending on your needs. For example, you may only need a 2×2 presentation (2 screens wide by 2 screens tall) or you may want to cover an entire wall with a vast digital display.

Video walls offer flexibility in the content you display. You can take one input and show this input across the entire video wall. For example, an advertisement like the one shown in the image below on a 2×2 video wall.

Alternatively, you can use a video wall controller to feed multiple inputs onto your video wall to show different content on different panels. For example, you could show different data dashboards or CCTV inputs

A wide variety of industries use video walls to convey information to a large number of people, whether that be customers or employees, such as:

  • Retail
  • Control rooms
  • Education
  • Government and public sector
  • Military
  • Healthcare

In a retail store, a video wall could display a video of your new product covering the entire display, while in a control room, different types of data could be shown on each screen for your employees. With their size and impressive displays, your information can be communicated quickly and clearly. Regardless of the location, video walls are an effective tool for showcasing your desired message and will have a memorable impact on your audience.

What are the benefits of video walls?

Effective external communications

How can video walls help promote your brand?

This technology can be used in a variety of environments to effectively communicate important information and to increase engagement with brand and product messaging.

With the large-format nature of the display, video walls are eye-catching and can engage a large audience at once.

This could mean impressing your visitors in the reception of your building while serving important news and health and safety reminders. In a retail store or shopping mall, the video walls could be used to promote new products and sales. Food and drink vendors in arenas could use video walls to showcase menu items and highlight product promotions.

Outdoor video walls, in particular, are expected to grow in popularity significantly over the next few years as the demand for outdoor digital advertising grows.

Internal communications and engagement

Video walls are an effective outlet for internal communications too. Many organisations use video wall displays in control rooms, command centres and simulation rooms. The size of the display allows for large amounts of data from different sources to be communicated quickly to a room full of employees. As new information becomes available the entire workforce can react as a unit. The increased collaboration can help you to hit deadlines and respond effectively to situations as they arise.

LamasaTech provides video walls that are ideal for control room environments. Chat with our expert team today to learn more about our best-in-class displays.

Long lifetime and low maintenance

Another benefit of video walls is that they require very little maintenance and are designed for long-term usage. Compared to an alternative, such as a projector, a video wall will last much longer and see less degradation in brightness and picture quality over time.

The life expectancy of a video will vary depending on how long it is used, if features like brightness are turned up to maximum and if the display is an LED or LCD. The average lifespan of an LED video wall is 100,000 hours while an LCD is expected to last around 50,000 hours.

What are the types of video walls?

There are two types of video walls – LCD video walls and LED video walls. Deciding which option to go for is your first step in selecting the video wall you wish to invest in.

We’ll cover the main differences below, but for a more detailed breakdown of the differences between LED and LCD video walls, please see this article.

The difference in technology

LCD video wall panels use Liquid Crystal Display (LCD) technology. LCDs are not light-emitting, which means that they have backlights (normally LED) behind the glass to illuminate the display.

LEDs use light-emitting diodes as individual pixels across the entire display. Each LED acts as a tiny bulb that emits colour when electrically engaged. There is no need for a backlight because the LEDs produce light while producing the image. The technology can be referred to as Direct View LED.

Neither option is universally better than the other. Which technology you select depends on your environment and needs. The main factors that will affect your choice are:

  • Resolution
  • Indoor or outdoor use
  • Brightness
  • Size
  • Cost

Resolution

The resolution plays a big role in determining the optimal viewing distance for your video wall. A higher resolution means that the content displayed will remain sharp and detailed when viewed up close from a short distance. This is ideal for indoor setups such as reception areas and control rooms.

LCDs offer the highest resolution of the two types of video walls. A 55″ LCD display will have a resolution of 1920 x 1080. The resolution of your full video wall will depend on the number of panels it has, for example, a 3×4 display will have a total resolution of 5760 x 4320.

LED cabinets will not have as high a resolution, plus the resolution will vary depending on the pixel pitch for your chosen LED display. You can learn more about pixel pitch and how it affects resolution here.

LED options are a great choice for outdoor installations such as at stadiums and along a roadside. These displays will be viewed from a distance so the lower resolution will not matter in these locations.

Brightness and environment

In terms of overall brightness, LED screens can offer a higher level. This is because LED screens can be used in outdoor environments, therefore they need a high brightness for content to be readable in sunlight. LED panels will go up to 6,000 nits in brightness. As LCD video walls are designed for indoor environments, they do not require high brightness levels and therefore range from around 500 nits to 700 nits.

Size

The size you want your video wall to be will be a factor in determining which screen type best suits your needs. LED walls can be scaled to a huge area. Think about the size of the outdoor LED walls you might see running advertisements on city buildings, like in Times Square in New York, or at stadiums and arenas. LCD panels can be tiled together to create a large display wall too, such as a configuration of 18×6 panels for a control room. Yet, LCD has a limit, whereas LED walls are pretty limitless when it comes to size.

Let us know what size you would like your video wall to be we’ll help you find the perfect solution for your requirements.

Cost

We’ll go into more detail about the cost of a video wall project later in this guide. Generally speaking, an LED video is much higher in cost. On average, you would consider a budget of around £5,000 or $6,000 for the lowest specification LCD video wall panels in a 2×2 set-up. Whereas, at the lowest end of LED, you would be looking at around £40,000 or $50,000 for an average project.

Power requirements

Due to the high-brightness capabilities of LED displays, they require a larger amount of power. A 55″ LED cabinet will be consuming around 600W.

An LCD of the same size will only need 250W of power at its peak.

If your organisation has green policies and is looking to use less power, an LCD option would help you to do that.

The table below summarises the key points to compare.

What to look for in a video wall

Once you’ve got a better idea of whether you are going down the LCD or LED route, you can consider the different specifications of the panels on offer to narrow it down to the model and configuration you want.

You can explore our range of video walls here, or get in touch and tell us about your project.

Brightness

Brightness is an important feature to focus on and the location of the display will determine this. In an indoor environment, you will not need as high brightness capabilities as you would outside. This is because brightness is used to counteract the effects of natural light shining on your video wall.

In outdoor locations or indoor areas facing sunlight, glare and reflections can make it difficult to see what is being shown on your display. A video wall that is capable of high brightness levels will be able to negate these effects. Outdoor displays are recommended to have up to 5,000 nits if they are in direct sunlight.

500 nits is usually a completely adequate level for your indoor video wall in standard ambient light, or you may need 700 nits if your video wall is in an area with a lot of sunlight, such as a lobby.

Contrast

Contrast is another key feature when choosing a video wall solution. Contrast is the range between the brightest part of the display and the darkest, this is measured as a ratio. The higher the contrast ratio the more detail and better quality image the screen can produce. A higher contrast also enables easier and faster recognition of the information being displayed to your audience.

Explanation of contrast on a video wall

Some LEDs can dim sections of their screens to make darker areas even darker, which helps to increase the display’s contrast ratio. If contrast is a particularly important feature for your video wall needs, then you should look for options that include this local dimming feature.

Bezel

If you choose an LCD video wall, one of the specifications to consider will be the bezel size. The bezel refers to the frame that goes around the edge of a single panel. When a video wall is built, the bezels of connecting screens meet. You will see this as a thin black line between the panels, as shown below.

Representation of an LCD video wall with an average bezel

You will often see bezel sizes like 3.5 mm and 1.7 mm listed. This size is the screen-to-screen bezel width. The thicker the bezel, the more you will notice a line between your displays, which can affect the viewing experience depending on your content. For example, if you want to display a lot of text or data on your displays, a thinner bezel could be a better choice.

As the technology has developed, video wall providers have been able to reduce the size and impact of the bezel on their displays. Some have been able to produce a display that appears seamless, like LamasaTech’s seamless LCD video wall. This is created using a bezel compensation process, which merges the pixels between displays where the displays meet on each edge.

Mounting system

Various types of mounts are available, such as a standard wall mount, a free-standing floor mount and a pop-out mount. Each has its advantages and it depends on your space.

Standard wall mounts are the lowest cost, simple to install and are sometimes offered free with your panels. The drawback is that the panels have to be removed for any maintenance.

A pop-out wall mount will give the easiest access to perform any maintenance from the front.

How do video walls work?

Normally when users ask how a video wall works, they are wondering how to control the content on a video wall display. In short, you will either choose to daisy chain your displays, or you will need a video wall controller.

Daisy Chaining

If you are looking to display a single piece of content across your entire video wall, such as an advertisement, you will most likely choose to daisy chain. Daisy chaining your displays allows you to present one input across the entire video wall. For example, a digital signage player could be your input. This input is connected to panel 1. Then each panel is connected to the next, which results in your one input being spread across all panels. The image below illustrates how this works:

How a daisy chain video wall works

Choosing a controller

If you wish to have multiple inputs connected to display different content across sections of your video wall, you will need a video wall controller. If you are building a video wall for a control room, network operation centre or command centre, you will require an advanced IP Based & KVM System.

Advanced video wall processor

Video wall processors have multiple inputs and outputs. With a processor, you can display different content instantly on different sections of your display. For example, you could have different dashboards and performance trackers on each panel.

Check out LamsaTech’s Advanced Video Wall Processor on this page, or let us know what you need from your processor and we’ll help you get the most out of your video wall.

You will select the number of inputs and outputs you require when purchasing a controller. For example, two input sources and four output sources. This means you can connect two different inputs (eg a digital signage player and a laptop) and control where they display on a four-panel video wall. It might also be worth future-proofing your controller. If you think you may expand your video wall in the future, it could be worth selecting more inputs and outputs than you currently require.
 
When looking for a control device it’s important to make sure it has the connection ports that you will need. For example, HDMI is a common connection to screens and processors.
 
The ease of operation of the processor is key. You should be able to easily drag, drop and resize your inputs onto different panels or sections (multiple panels) of your video wall from the processor software. A great feature to look out for is a preview feature, so you can preview your different inputs and how they will look on your video wall within the software. A web application can also be incredibly useful if you want multiple employees to be able to change the video wall layout. This means employees can access the web app via a browser, rather than having to download the software suite onto their PC.

IP-Based & KVM System

The best solution for a control room, network operation centre or command centre is an IP Based & KVM System. KVM stands for “keyboard, video, mouse,” and means you can control multiple computers from a single keyboard, mouse, and monitor. Some KVM switches are local, which means they can control nearby servers and computers. IP-based KVM switches allow for IP-based remote access. For your video wall, this means you can control multiple inputs from anywhere in the world that has an internet connection to your network.

If you need a control room video wall solution, contact LamasaTech today and we’ll provide you with expert guidance.

The three main components of the solution are:
– KVM node which connects to the input source (e.g. a PC, server, thin client terminal)
– output node which connects to an LCD panel or LED sending box
– operator station where you can control your inputs and outputs remotely

Unlike traditional command centre solutions by video wall matrix, this system does not require a standalone server or video wall controller and there’s no limit on the channels of inputs and outputs to the video wall. Since there’s no server, a bug in a single KVM node will not affect the entire wall.

How much do video walls cost?

The cost depends on what your needs are. A bigger video wall will be more expensive. Many providers are happy to provide a free consultation to discuss your requirements and follow up with a personalised quote. Prices normally start around $5,000 or $6,000 for the lowest specification LCD video wall in a 2×2 set-up. Whereas, the budget for an LED video wall is much higher and on average starts at around $40,000 or $50,000. You’ll also need to add on the price of the mount that you select.

The main elements that will affect the cost of your video wall are:

  • indoor or outdoor environment
  • total dimensions of the video wall
  • LED or LCD panels
  • bezel size (for LCDs)
  • brightness
  • resolution
  • mounting system
  • video wall processor (if required)
  • installation and training (if required)

An LED solution that has full-array lighting will be the more expensive choice but for that price, you will get the best picture quality and the most flexibility when it comes to the shape and size of your video wall.

You also need to take into consideration the price of your control device. Depending on your requirements, you may be happy to daisy chain your screens without the need for a control device. However, if you want to feed multiple inputs into your video wall or are looking for a control room environment, there will be an additional fee for a video wall control solution.

You may wish to pair your video wall with a digital signage system to create and schedule the content for your display. For the subscription price, you’ll gain benefits such as cloud storage capabilities and support for additional screens.

LED wall displays range in price depending on their size, panel quality, installation type and pixel size. In general, the cost for an LED video panel is between $600 and $3,000. 

Most LED video wall systems consist of several panels plus additional components like audio and processing equipment, which adds to the final cost. Turn-key LED video wall systems can cost anywhere from $10,000 - $50,000+.

LED walls are a huge asset for businesses, venues, churches, or other organizations that host frequent events. If you’re considering purchasing LED products for your space, you may be wondering what the pricing will look like and how to budget for the cost. Keep reading to learn about the four factors that influence LED video wall cost.

1. Product Sizes

It’s probably unsurprising that the size of your LED products’ screens will influence the cost of your project. If you’re unsure what size you need in the space, reach out to an LED company and see what they recommend. The best screen or panel size for you depends on the size of your room or venue and the number of seats in that space. You should also consider your organization’s goals and needs to help you find the perfect products.  

Most panels we use for clients are 1.5 ft X 1.5 ft and can be “built” together in many designs and layouts. Some projects utilize these panels for design, while others build a larger screen. There is no limit to the creativity you can have with your LED panels. If it fits in your space, we can help you create it. Some clients opt for 40 ft X 60 ft, while others prefer 5 ft X 8 ft or choose a different custom size.

For screens under 100 inches, we often encourage customers to incorporate televisions in their design. When it comes to TVs and LED video wall cost, pricing and value for the technology directly correlate. TV screens under 100 inches are generally cheaper than LED panels. The price jumps drastically for TV screens over 100 inches, and at that point LED panels are a more cost-effective technology.

2. LED Panel Quality 

The quality of your product is a major factor in its overall price. If your LED Wall quote seems extremely low, you should ask yourself why. Equipment that works well for years to come will likely fall in the mid-to-high price range. 

Here is a short list of components and features that could impact LED wall prices. 

  1. Refresh Rate: Refresh rates matter with LED panels, especially if you do any sort of broadcasting or online live streaming. Standard Panels come in refresh rates of 1920hz. Upgraded Panels come in refresh rates of 3800hz or higher, thus giving you a greater quality image when being seen online or TV. 
  2. Receiving Card: To put it simply, this multi-function card is the overall control system of the LED panel. This collects and transfers data to the LED screen. A poor-quality card or a high-end receiving card will undoubtedly determine the output quality of your LED Wall. Our recommendation is a Novastar A5S card or higher.
  3. Serviceability: Can your LED Panels be serviced entirely from the front? If so, then your modules, power supply unit, receiving card, and HUB board should all be accessible from the front side of the LED wall. This is an important feature for future servicing and maintenance. 
  4. Lifespan: How many hours is your LED panel rated for? Most panels are rated for at least 50,000-100,000 hours. The higher the rating, the higher the price point. 
  5. Added Features: Manufacturers can add what we call “bells & whistles” features to LED panels. These special features include rear display screens, temperature gauges, corner protectors, detachable cabinet doors, latches, and extra handles.

3. Installation and Design Preferences 

The design, goals, and needs of your project will all influence the final cost. Although custom sizing doesn’t necessarily increase the cost of a project, it could. Understanding how custom sizes affect the user experience is really important. If you’re unsure what sizing or dimensions you need, we recommend engaging with an organization like Refresh LED that can offer insight. 

The installation of your project will also factor into the final cost. Our LED products can be hung, ground supported, or mounted directly to a wall. Whatever the design aesthetic you’re looking for, these options are available, and prices can vary for each. 

4. Viewing Distance 

Have you ever driven past an electronic billboard at night and seen an advertisement or graphic? From 50 feet away, the image looks great! But if you were to walk up 5 feet from a billboard and try to read it, the pixels in the screen become extremely blurry and hard to make out. This is called the viewing distance. With LED walls, pixel size and viewing distance are important in designing your project. 

The pixel size for most LED walls or panels is a standard 3.9 mm. This means that the pixels within the screen are 3.9 millimeters from one another. This screen size is great for viewing from 10-15 feet away from the screen. Much like the billboard, when you look at the screens from a closer distance, the content begins to get pixelated and blurry.  While in person events were on hault however, 2.9mm became a necessity for many projects due to live streaming and recording becoming so prominent. Cameras interact with screens in many different ways, if a pixel pitch is to big for exmaple, you might see scan lines or a moray effect. If live streaming or recording is an imporant factor for you then we recommend a 2.9mm pixel pitch or lower.

3.9 mm and 2.9 mm LED screens are the best value in the market currently. When you choose a pixel pitch smaller than 2.9, the project's cost becomes considerably more expensive. For viewing distances less than 5 feet and dimensions smaller than 100 inches, we encourage our customers to look into a TV.
