Besides, it receives and processes a variety of video signals and forms a large, unified image.  It will then show parts of this image to individual screens of your LED display, which will create one cohesive image.

The LED video processor is also responsible for making it possible for you to have a single image that appears and moves across several LED screens seamlessly. Without video processors, your LED screens can only display different images on each screen.

This device utilizes video image and HD signal processing technology. You can manage your screen resolution format and the RGB chromaticity of your LED display using this device.


2. What Does A Video Processor Do?


The video processor is a crucial element of any large-scale LED video wall display. The main functions of an LED Video Processors are as follows:

  • Multi-screen Processing.

On many occasions, you will need to have your LED screen display multiple images. A video processor is a device that has the function of processing multi-screens. It allows you to manage your large LED screen easily. The video processor is the one that receives various inputs and puts them all together.

  • Image Scaling.

The video image signals need to be scaled to match the screen resolution of your LED display. The role of a video processor is to scale your video images both vertically and horizontally. This scaling will help you achieve excellent picture quality by the pixel resolution of your content and LED screen. A video processor is also capable of converting low pixel resolution into higher resolution using its HDMI output.
