How to Decide to Purchase a Video Wall

Your video wall purchase decision is about more than the cost or return on investment, although these factors are essential. It’s also about making sure that the solution best fits your use case. The goal is to find the most appropriately seamless visual experience for your audience and objectives.

We’re here to help you ask the right questions and, ultimately, find the right answers.

1, Screen size and number of panels

Before you buy your video wall, you’ll have to establish the scale of the screen you want. The answer to this will greatly affect which video wall you choose (and how many panels you’ll need). Your decision will depend on how and where your video wall will be used. It will also be determined by the space you have available. You should also consider what you will be displaying on the screens and how the native image size will look on varying screen sizes.

A combination of all these factors will help you decide the size and number of panels you need.

Most video walls will be LCD displays which can offer high total resolution due to their high pixel density, high brightness options, broad color spaces, wide viewing angles (up to 178 degrees), and are moving towards extreme narrow bezel models. LCDs are ideal for showing detailed images.

Another option is LED displays. LED panels do not provide as high of a resolution and pixel pitch as LCDs so you’ll only want to use LED when the video walls are being viewed from further away. Intense brightness (from 800 nit for indoor to 6,000 nit for outdoor) is a feature of LEDs which makes them great for outdoors with direct light emission, but the downside is that they are unsuitable for dark rooms. When viewed from the side, they can also appear less bright and with greater color variability to LCDs.

2, Bezel size

Bezels are the edges of individual panels that can be seen as black lines or gaps between the panels. The smaller the size of these, the less disrupted your images will be.

Minimal bezel sizes reduce the visual disruption caused by black grid-lines in large video wall images, mitigating potential display issues such as aesthetic value and practical usage.

Available bezel sizes for your video wall depend on the technology behind the individual panels that make up your overall display. LCD panels are increasingly available in extreme narrow bezel formats, which reduces bezel width (bezel-to-bezel) to 1.7mm from a standard 3.5mm. LED panels can already produce bezel-less displays. And although DLP panels require a bezel, these can be as narrow as 0-0.5 mm for nearly seamless viewing.

3, Environment and temperature suitability

Your video wall’s performance can be affected by environmental elements such as light, heat, moisture, and air quality. Efficient and enduring video walls must be able to tolerate long hours of use, high temperatures, ambient dust, and humidity – wherever they are used.

Make sure you’ve evaluated the factors in play at your video wall installation site, so you’ll know which additional environmental protection features may be necessary.

For example, ambient light can affect the native contrast ratio of displays. In high ambient light, your display needs a high contrast ratio, and an anti-glare solution to minimize direct reflections of nearby light. High contrast ratios maintain image vividness with deeper blacks that come through even near sunlight.

Generally speaking, LEDs have a long and useful life and can withstand outdoor conditions well with weather resistance to a range of temperatures and humidity levels.

4, Budget

Video walls are a cost-effective way of deploying a large scale of digital display solution. In comparison to alternative options, such as costly LED tiles, video walls offer unbeatable value for large screens.

A quality video wall investment will save you money in the long run, even if the upfront costs are slightly higher. But be careful not to fall for an attractive offer price. Low-quality video wall installations can carry future maintenance and replacement costs that easily exceed any initial savings.

5, Reliability and warranties

To get the most out of your video wall, you’ll need a display that is purpose-built for 24/7 operation. We also recommend that you buy from a manufacturer that provides a warranty of at least 2 years.

For longevity and reliability, look for panels with vertical alignment technology and high TNI liquid crystals. For the best value product, you’ll want a video wall that is resistant to heat, moisture, and dust and protects against black spot.

Another area to take into account is service. Due to the investment cost of a large scale of video wall, professional design and installation are recommended to ensure dependability. Evaluate your supplier’s installation service before you purchase.

Video walls require a professional solution designer and installer who will take into account a number of factors; including video wall parameters (i.e. screen size, brightness tuning, bezel gap) and third party equipment (mounts, cables, switchers and/or video wall controllers). Otherwise even simple mistakes can produce a poor overall result.

The more informed you are on the factors that determine which video wall is best for your business – from budget and maintenance, application, and positioning, to size and performance – the more likely you are to invest wisely.
