3	Picture stitching setting window, displaying a virtual large screen stitching image.
4	Status bar: It can display information such as operation prompts and physical parameters.

3.3 Stitching settings

The splicing settings are used to set the splicing mode of the processor. Click "Video Wall" in the menu bar, the following interface pops up, including setting, Screen Map, Control, Device Version.

In the splicing settings interface, you can select the screen grouping, large screen type, set the physical screen arrangement, edge width, logic sub-screen, output resolution, and customize the output resolution. 1.“Group”： Support 4 groups of screen grouping, can customize the screen grouping situation;

2.“Type”： Support LCD、LED and matrix three-mode display settings;

3.“Physical Screen”： The actual combination format of large-screen displays, this software can support up to 20 x 20 combined format stitching. Combined with the output channel of the application device and the application requirements, the splicing combination format can be customized; “Logic Sub-screen”： A sub-screen that is virtualized on each physical screen (here

4.defaults to a 2x2 sub-screen, and up to two sub-screens can be set in the vertical and horizontal directions);

5.“Edge Width Setting”： The value is 0-100. When the display device is a liquid crystal display, the black border between the screen and the screen will make the image have a split vision, and the display effect is poor, so the frame compensation function is needed. The software's "edge width setting" can achieve this function;

6.“Output format”： The system comes with a regular output resolution, you can also create a new resolution for the screen by clicking the "Add" button, the new resolution will be added to the "Resolution" list;4.defaults to a 2x2 sub-screen, and up to two sub-screens can be set in the vertical and horizontal directions);
