Video wall solutions

Video walls, sometimes referred to as display walls, are expansive visual platforms made up of an array of displays working in unison. In their initial conception, these structures were simply clusters of televisions or monitors positioned side by side. The primary goal was to create the illusion of one seamless, large display area.

One significant challenge, however, was the bulky frame, or bezel, that encircled each television's functional viewing area. This substantially detracted from the illusion of a singular canvas and compromised the overall visual experience. As a result, advancements in technology emerged that aimed to reduce the 'dead pixel space' separating various displays.

Modern video wall solutions predominantly utilize tiled LCD screens, rear-projection cubes, or direct-view LED panels. These systems find their application in various fields, including command centers, conference rooms, digital advertising, and other high-demand environments.

These video wall systems come in various sizes, typically featuring screen dimensions ranging from 46 to 80 inches. The selection of screen size is dictated by the type of content displayed and the viewing distance. When viewed up close, higher pixel density is crucial to prevent individual pixels from being discernible. The resolution correlates with the overall wall dimensions; for instance, a 4K video wall necessitates four Full HD monitors arranged in a 2 x 2 configuration.

While each technology showcases unique advantages tailored to specific user requirements, there are several commonalities among them:

• Require a video wall controller to manage content on the displays
• Exhibit remarkable flexibility in terms of size (number of individual screens)
• Need a calibration mechanism to ensure uniform brightness and color settings across all screens. Barco's automatic calibration technology achieves this in real-time, optimizing both single displays and entire video walls.
• Demand minimal inter-tile gaps (ultra-narrow bezels) to combat the 'raster effect'.
