Video walls are incredibly useful and impressive solutions for indoor applications, outdoor retail, menu boards and billboard advertisements, to name a few.
In fact, the video wall industry is showing impressive growth, such that the market size is expected to be worth almost $18 billion by 2020.
Key trends driving this growth include the continued adoption of video wall solutions by the retail vertical and increasing demand from the educational and corporate segments.

Because video walls can be expensive, solution providers can expect customers to have several questions beyond where to place them and how much “wow” factor they deliver.
These are some of the questions your customers may still have about video wall installations:
1. Where Do I Start?
The best place to start is with a well-organized plan. After that, you’ll need to determine the size and characteristics of the room and the space allocated for the display wall. If you’re designing a video wall solution for government use, ask what size the control room or command center is, including floor dimensions and ceiling height.
Content determines the types of displays you’ll need. If you plan on mixing it up with static images, short animations and video, you may need specialized software and/or media players able to output a variety of content from mixed sources.
2. How Do I Choose a Mounting System?
Almost every pro AV professional who has had to deploy a video wall for a customer has at one time or another had to address the unique challenges of selecting a mounting system.
Many of these challenges are related to design and environment, while others pertain to the size and configuration of the wall or the need to enable touch functionality.
For example, a 2 x 2 video wall mounted to a wall surface may benefit from the use of slide brackets, which are widely available and allow for precise alignment.
However if the video wall is going to be mounted in a recessed wall pocket with limited clearance on the sides, then a pull-out mount would work better for immediate service access and easier maintenance.
3. Are “Prosumer” Displays Just as Good as Commercial Displays?
The decision to use prosumer (consumer/commercial-grade hybrid) video wall displays is almost always a budget-driven decision, but these hybrid displays should not be considered an equivalent substitute for commercial-grade displays.
On one hand, a prosumer display may be less expensive but might not cut it as part of a professional installation for the following reasons:
- Bezels – Prosumer displays have wider bezels than their commercial-grade counterparts. Commercial displays have bezel widths of 3.5mm or smaller, while a prosumer display typically has bezel widths in the 10mm range.
- Brightness – Most commercial-grade LCD video walls offer two brightness levels. The lower brightness level is typically 450 to 500 nits, while the high-bright option of 700 to 1,500 nits can be deployed in areas with lots of indirect sunlight. Prosumer displays are typically rated at 450 nits or lower, limiting where they can be placed.
- Anti-Glare Coating – Prosumer panels do not feature the same anti-glare coating that commercial-grade panels do, meaning a noticeable glare, even if the video wall is located in areas with limited lighting.
- 24/7 Applications – Commercial-grade video wall displays are rated for 24/7 use, whereas prosumer displays often are not.
4. Do I Really Need 4K?
Despite its high price (relative to HD displays) and the persistent scarcity of 4K content, the hype surrounding 4K monitors continues to grow. Deciding on 4K displays really depends on the type of content you’ll be using and the type of impact you want your audience to experience.
For most applications like those used by the hospitality, government and education verticals, HD displays should work fine unless your display solution involves a touch screen or highly detailed maps—then 4K may be the route to take.
5. What’s My Total Cost of Ownership (TCO)?
Video wall systems typically do not need replaceable parts and do not require regular maintenance, factors that make them less expensive to operate over time than, say, projection systems.
Video walls also have much lower power-consumption requirements than many competing technologies. Still, video wall TCO can add up when you take into account things like network configuration, installation and service costs, content creation and facility management costs.
The best way to keep TCO down is to make informed purchasing decisions and buy the best mix of video wall components and servicing that your budget allows.
