What Is A Video Wall?

A video wall is a collection of screens used to display one or multiple coherent images. The resolution of the video is the sum total of the individual monitor’s screen resolution. Video walls can display one large image to create your very own movie theater experience, or isolate each monitor to revolutionize your conference room experience.

You may have seen a video wall before without even realizing it! Video walls are most prevalent in spaces where information needs to be given out to lots of people at once. An example of this is a train station where screens display train platforms, times, and destinations. Video walls allow information to be centralized to minimize confusion and miscommunication.

Video walls can be used in the following settings:

  • Sports stadiums
  • Offices
  • Home theaters
  • Transport facilities
  • Museums
  • Newsrooms
  • Mission control centers
  • Security facilities

Just for your information, the video wall market is expected to skyrocket in the next five years to almost 24.5 billion dollars’ worth in industry!

How Does It Operate?

Video walls require extensive management in order to create engaging and informative displays. Processors, matrix and different kinds of monitors all contribute to creating your perfect video wall experience.

Your choice of video wall management systems should be mostly dependent on your project requirements, as this can optimize your video wall experience. Below, we’ve listed all the essential components of a video wall and how they contribute to your experience:

Video Wall Processors

Most video wall projects require processors or controllers to process input signals and display content on any of the screens. Video processors are essential for managing large quantities of data, so the more sophisticated your AV project is, the more you will need a processor. Processors allow users to create effects, play audio and isolate individual screens to create a truly engaging display in their home, office, or entertainment facility.

LCD Panels

LCD panels are the most traditional example of a video wall and create effective displays by grouping LCD monitors together. There are some drawbacks of LCD panels as they use significant energy and have some interruption in display due to screen boundaries.

Rear Projected Cubes

Rear projected cubes integrate projection and screens to create a seamless and detailed display. They consist of multiple cubes to narrow the screen boundaries and ensure image continuity.

LED Panels

LED panels are great for displaying highly detailed bright displays for museums, shopping malls, and newsrooms. LED panels are thin and have very few boundaries, improving user experience significantly. In fact, LED panels have seen considerable growth over the last few years due to their energy efficiency and better alternative to LCD panels.
