Video walls have become increasingly popular in recent times, especially in control rooms and for entertainment purposes. They are also often used to make fast and accurate decisions when people are working as a team, or for projecting messages that need to be seen by a large number of people. So, it is clear that there are many uses for video walls, both for business and leisure purposes.
As well as this, there are different video wall technologies available, including Rear Projection Cube (RPC), direct view LED and only tiled LCD, among others. Because of the availability of different options, it is paramount to know what to consider when purchasing a video wall. Below, we have outlined some considerations to take when you are choosing a product that is right for you.
Quality of the Images
It is paramount to select a video wall that will be able to display the images that you want to convey with clarity. This means that you should look for a video wall that can give you a crisp image quality on a large scale, one in which your images can be upscaled without compromise. Features such as the color, consistency of the contrast and brightness of the video wall are the ones that determine the quality of the images.
It is also helpful to consider whether these features are controlled manually so that you know whether it will be easy to change these particular features depending on the images being displayed. We would say that this is probably the most important feature for you to consider. After all, a video wall is a visual medium. Without picture quality (and this is irrespective of the purpose of your video wall), your video wall will not have the desired impact.
Viewing Distance and Angle
It is also important to determine the viewing angle and distance of the video wall from your intended audience before purchasing. The importance of this is to ensure that the people who will be using it will be able to view everything clearly depending on where the video wall will be placed. The operator of the video wall should be able to view everything, even when on a tight angle.
Often video walls are utilized in large venues, and this makes the placement of the video wall all the more important. Without giving this a lot of thought, you may not give the device the opportunity to make the desired impact.
Serviceability and Reliability
A video wall becomes an integral part of any business, where it needs to be operational around the clock. If it breaks down, it can result in a crisis, as you may not have the expertise in house to fix it. The ideal video wall should be easy to repair if it does experience a problem. The spare parts to do the repairs should also be readily available so that it can be fixed quickly.
It is also helpful to get a video wall that is designed to work 24/7 without needing to be switched off so that it can cool off. This is a particularly important economic consideration, as video walls can cost tens of thousands of dollars, which means that you will want to make sure that you can make a return on your investment.

Upgradeability and Lifespan
The common video walls that are available on the market have lifespans of about eight years. However, there are some which have longer lifespans, such as the laser illuminated models which have lifespans of about eleven years. The one you choose will determine how long it will take before you need a replacement. It is advisable to choose a video wall with supplier End Of Life (EOL) and End Of Service (EOS) policies.
When it comes to upgradeability, you should ensure the one you choose can be upgraded in the future as technology advances. As we mentioned above, choices like this can be a very important indicator of cost, and should not be taken lightly.
The Total Cost of Ownership (TCO)
This is the total cost of ensuring that the video wall remains functional and it is serving its purpose. The cost includes maintenance, cooling, procurement, and operation. While considering this, it is important to consider how long the video wall will remain operational. It is also helpful to consider at what point the video wall might need to be replaced or to be upgraded.
As we have outlined above, video walls can be extremely useful, both for leisure and business purposes, and they can be an extremely astute investment. If you take account of the tips above and do not make a quick and ill-informed decision, then a video wall can be an amazing addition to your business or home.
