Projection unit display quality has a direct impact on the effectiveness of the entire projection walls, using different types of projection units will get very different results. Image processor is the heart of the projection wall system. Its role is to bring the computer, video, Web, etc. to display the signal sent to the image stitching controller, processed image signal is sent to the appropriate projection units, each projection unit shows only one part of the whole image, all projection units together constitute a complete Super resolution, large screen, large screen resolution for each projection unit multiples of the resolution. Each signal of the image are displayed in a window in the projection on the wall. Window position, size, quantity can be changed. Big screen management is implemented by the software. Big screen management software for: projection walls, window works, network control, matrix switches, and other functions.
