Video Wall System Basics

What is a Video Wall System?

When you think of a video wall system, what comes to mind? For most people it’s the displays that make up the video wall itself, which are a group of screens tiled together to create a single, large video surface.

While the display wall is certainly the most visible part of a system, it’s actually just only one piece of a complex solution. Have you ever wondered about the technology behind a video wall? What does it take for those individual screens to “talk to each other” and act as a single display surface? How do you control what appears on the wall and where? What is used to get your content onto the system to begin with?

To help answer these questions, join us for a quick tour of video wall system basics and the components of a typical solution.

1. Video Wall Displays

Video wall displays provides a largescale, high-resolution “visual canvas” for your content.

Quick facts:

  • A display wall is usually made from a tiled arrangement of monitors, panels, or projection screens. Tiling multiple display panels together can create an extremely large, multi-HD display surface.
  • A large range of display technologies are used to create video walls, such as LCD, LED, projection cubes, blended projection, and more. Each display type has specific pros and cons in terms of resolution, brightness, reliability, cost, and other factors.
  • Depending on the display type and its mounting system, video walls can be built in flat, curved, or even three-dimensional shapes. They can be small enough to be portable or large enough to fill a multi-story atrium.

2. Video Wall Processor

Video wall processors, also known as controllers, connect your content sources to the displays. They let you control what content is shown on the video all, when and where it appears, as well as how it looks.

Quick facts:

  • Using IP streaming or physical inputs, the processor captures content from all of your desired sources such as video cameras, computer workstations, and cable boxes. The controller makes the content visible and accessible on a single interface.
  • Based on the commands you make through the control software, the processor sends content to the displays and lets you arrange, scale, and adjust the content in real-time. Some controllers also let you build and save content arrangements offline before displaying them as custom layouts.
  • The processor allows all of the individual displays in your video wall to work together as a single canvas. This means that content can be placed on a single display, stretched across multiple displays, or dragged across the display surface.

3. Video Wall Software

Video wall software provides a user interface to control your displays, processor, connected system devices, and source content.

Quick facts:

  • Most video wall management software provides a “dashboard” of the system that includes a real-time view of the displays and a list of your available content sources.
  • At its most basic level, the interface allows you to select content sources and place them on your video wall in real-time. Most programs also include tools for adjusting the appearance of content such as scaling, zooming, and cropping options, brightness and contrast controls, and so on.
  • Some video wall software offers special presentation-building functionality. This may include the option to build and save a sequence of pre-arranged content layouts, which can then be presented manually or automatically on the displays. Select platforms also offer custom labels, graphical transitions, and other tools for enhancing presentations.
