A videowall is a bank of displays, placed and unified together to create a single larger screen. While this can make a major artistic impact, it has practical uses for producing more effective visual communications as well. A set of displays can serve a useful purpose in venues that see a lot of foot traffic, or spaces that are particularly large. Stadiums, convention centers, airports and universities are some venues that can benefit from the technology, but they also make sense in control rooms. However, setting up such a system is a complex process, and takes special knowledge to handle the project effectively.
What exactly can a videowall be used for?
This technology is much like standard display technology, except it can adapted for much larger applications. Single screen devices, while useful in a number of settings, are harder to manage and manufacture as they are made larger. As screens increase in size, eventually it is no longer cost-effective to stick to a single display option, and it makes more sense economically to go with multiple displays. Enormous screens tend to be more fragile as well, and the bezels built into a tiled display add structural integrity to the installation.
With multiple displays, a business or venue can expect greater image resolution as well. It is difficult to maintain adequate pixel density at extremely large sizes, and a set of smaller displays preserves this density. Because of this, a videowall offers great image clarity from multiple ranges, including long distances. This high-resolution at a distance is the primary reason why stadiums and concert halls opt for the technology. Staring at low-resolution screens for the entirety of a sporting event or concert can leave people with headaches and eye strain. Higher resolution screens handle this concern with ease.
Another significant benefit to the technology is its added versatility and artistic capabilities. As each display can be independently controlled, a venue has additional options for presenting images or text. For example, a 100 inch videowall installed at the Lafayette Library and Learning Center cycles through photos displayed on multiple monitors, while a single monitor is reserved for event schedules and other announcements. The ability to present images in a new way gives venues and artists a lot of creative choices, many of which can do a better job of grabbing peoples’ attention.
What are the challenges with the technology?
It does take additional expertise to set up a bank of monitors, as they require more power and additional infrastructure to operate. Special video cards and graphic processors are often required to run the display effectively, and arranging all of the displays and their bezels requires a strong anchoring spot that can accommodate cables and networking infrastructure.
Fortunately, AV integrators like Data Projections know how to make this infrastructure work, and how to customize a set of displays to meet their client’s needs.
