What equipment is used to control the video wall?

Due to the impressive image scale that a video wall can transmit, the signal quality is an important condition for its successful operation. That is why special attention should be paid not only to the characteristics of individual panels, but also to the equipment for their synchronization and control. If we are talking about a really bulky structure, then controlling multiple modules turns out to be an extremely challenging task. For this reason, signal processing and transmission is carried out using a special and expensive device – a controller. In some cases, more budget options are used to control a video wall, but we will analyze them in order.

Budget option for video wall equipment

The most budget option for video wall control equipment is a sufficiently powerful computer equipped with multi-channel video cards, with the help of which the video signal is transmitted. Thus, the function of the controller is performed by a video server specially created for these purposes. This approach has a number of disadvantages compared to the use of special, professional equipment for video walls. First of all, the video server imposes limitations related to the absence of some input ports and the impossibility of overlaying additional layers on the broadcast video.

Professional video wall equipment

A professional and at the same time quite expensive option for controlling a video wall is a special controller that can receive data from several sources, and then process and broadcast it to a virtually unlimited number of video wall modules. The content presented with the help of the controller becomes higher quality due to the increased detail of the image, and the ports are represented by both digital and analog inputs, which allows you to create a whole combination of images with additional layers and windows on a single canvas. It is also important that the controller often differs from the video server in a more stable and reliable signal.
