1. Overview
Multi-screen processor, also called multi-screen display controller, is a dedicated image
processing device based on certain operating system platform and offering multi-screen
driving function to perform remote display and control on various types of signals through
different modes. Generally speaking, it is a computer system with power functions.
However, different from the ordinary computer system, it is also a powerful image server
system.
When there is no multi-screen processor, the signals from the signal sources can still be
directly input to the digital display wall for display, but the display capacity of the digital
display wall system is completely subject to the display capacity of the display wall. The
application of the multi-screen processor can realize the processing and conversion of
signals before they are input to the digital display wall, thus greatly expanding the display
functions, application scopes and application methods of the display wall. It is a component
of great significance in the digital display wall system.

management on hardware resources in the display wall system (e.g., the display unit, multi-
screen processor and other peripherals), so as to realize the management and control on
the signal windows and application windows shown on the display wall. The VWAS can
make full use of the network distributed software system, support simultaneous connection
and operation of several clients, provide simple, friendly and customizable man-machine
interface, thus realizing quick and convenient control and simple operation on the combined
display wall, and completely eliminating the defect of traditional display wall, i.e., complex
operation.
Introduction to main functions of VWAS
To control the multi-screen processor, and operate the relevant windows and
applications on the multi-screen processor (the multi-screen processor windows
include the application window, video window, RGB window , Vlink window, HDMI

To realize the orderly batch operation on the multi-screen processor window and multi-
screen processor applications through the preset mode and scheme (you can
customize the operation modes and schemes according to the actual situations);
To realize the joint control on the relevant peripherals, such as the matrix, camera,
multi-screen equipment, and image splitter;
To provide functional module and equipment expansion and support the development
of the third party;
To provide software registration and hierarchical control of users (users that log on the

4) The display terminal (e.g., display wall) problem;
5) Other unknown reason
Troubleshooting method
1) Check if the signal cable of the multi-screen processor is properly connected, and if the
grounding is normal.
Besides, if the non-original signal cable or other poor quality cable is used, the image
display will be adversely affected. Please check and correct such undesired use.
