Videowall:What is it?

A video wall is a system of video display devices (projection cubes, plasma, or LCD displays) that are interconnected and form a single screen that allows you to display large amounts of information from different sources in multiple windows. A large number of video sources is very important when using the system for operational decision-making. By comparison, a traditional projector can use a maximum of three sources.

Due to the modular principle, you can create video walls of any size, there are screens of over one hundred square meters. The only condition is a multiple of the size of the video modules from which the video wall is assembled.

Hull gaps (edging) of the modules, when viewed, will distort the image, so an important factor in creating video walls is seamless. In addition, small seams are especially important for mapping (objects falling on the joints of the screens should not be lost). Modern projection modules after installation allow you to leave an almost imperceptible seam of less than 1 mm.

If the size of the room does not allow the use of projection cubes, LCD displays can also be used to install a video wall.

There are several main characteristics of video walls:

A number of panels (modules) of which the video wall consists. The most common options are 2×2 and 3×3 video walls.

Diagonal. Usually, it’s 55- or 46-diagonal, with a special professional matrix (P-IPS), which is designed to work 24/7 for several years. This is exactly the main difference between video wall panels and household TV sets whose matrix is designed for continuous operation for only 12-16 hours instead of the 24 hours of professional video wall displays.

The seam thickness, or “frame,” as it’s also called. Modern versions are 1.7-1.8 mm or 3.3-3.5 mm seam. Walls with such seams are also called “seamless video walls. The 5.3 mm joints and above are considered outdated and we do not recommend purchasing panels with such joints, since there is a chance they will be discontinued this year.

Display brightness. The standard brightness of video wall displays is 500 cd/m2 (candel per square meter). There are also panels with the brightness of 700 and 800 cd/m2, but they are usually used for rooms with high illumination, so you can clearly distinguish the picture on the video wall.

Type of mounting. The main types of video wall mounts are wall, floor, ceiling, and floor-ceiling.

A number of sources. If you have only one source, then you do not need an additional controller to display the content on the video wall. In that case, the video wall simply serves as a large monitor for your computer, laptop, video player, or any other device from which you want to output content to the video wall.
