Video walls

Video walls

A big picture is a prerequisite when displaying content in front of a large auditorium, and it simultaneously means better view of numerous details for many people at the same time. For decades, the projectors have been serving as the simplest and the most convenient solution for big displays, but there’s a series of situations where a projector isn’t the ideal choice. An image projected from only one projector usually doesn’t have a high enough resolution, which isn’t bigger than 1920×1200 pixels even with the strongest projectors. Also, projectors have limited brightness strength and are less convenient in brighter conditions. The principle for getting a big picture on video-walls is getting an accumulative image by means of several smaller elements, and by adding the dimensions and resolutions of individual elements this picture can be of enormous dimensions as well as an exceptionally high total resolution (e.g. by placing 4 HD-resolution screens in a 2×2 matrix you can get a resolution of 3840×2160 pixels).
