Before you invest in an LED video wall controller, you have to be sure that you’re getting the complete set. Here are some of the components of the controller you want to get. 

LED Display Control System

This component refers to the ensemble of the main LED unit board and all the other factors that are connected to the board to make it operate, including the power source, data and power cables, as well as the control cards. 

When it comes to the LED display control system, you have the option of choosing between synchronous and asynchronous. The former produces real-time content with the help of devices like cameras while the latter uses different sources like a computer, flash drive, or CD. 


The LED video wall controller also has a scanner. It helps set the brightness and color contrast of all the LED modules connected in the ensemble. There is a static and a dynamic scanning board and you have the power to choose which is the ideal one for you. The former is all about low-res content while the latter is capable of generating high-res content. 

LED Video Controller

An LED video wall controller sends and receives data from a specific content source. The content source can be in the form of cameras and computers, depending on your requirements. The data is processed and you can edit it however way you want to. Once the data are processed, they are transmitted to the LED modules and screens for showing. 

Cooling System 

This component helps regulate the LED controller’s temperature. It helps prevent the controller from overheating, especially since it produces heat with its operations. The cooling system comes in the form of fans that inject airflow into the device or a heat sink that takes out the heat from the system. A liquid cooling system can also help by distributing moisture all over the device.
