The Vdwall LVP615 series processor displays the entire picture as a whole instead of multiple small images by using a synchronization and mosaic function. The process involves:
1. Signal Input and Distribution: All input signals are connected to and switched by the primary processor (#0 LVP615). The same DVI outputs from #0 LVP615 are then looped to other processors (#1, #2, #3, and #4).
2. Image Cropping and Scaling: Each processor (#1 to #4) crops and scales a portion of the image according to predefined parameters. The total LED width is set to 3456 pixels, and the total height is 1920 pixels. Each unit covers a specific section of the display.
3. Mosaic Function: The processors are configured with the correct horizontal and vertical start positions (E.6 and E.7) to ensure that each unit only processes its assigned part of the image.
4. Synchronization: The mosaic function is enabled, and synchronization is turned on to ensure that all output images align correctly without delays or mismatches.
5. Automatic Calculation and Adjustment: The APP calculates and applies the parameters automatically, and manual adjustments can be made if needed.
By following these steps, the processors work together to output a seamless, synchronized image that spans across multiple LED screens, displaying the entire picture as a whole.

Questions and answers
How can we get the processor to reflect the whole picture instead of several small images ?
The Vdwall LVP615 series processor displays the entire picture as a whole instead of multiple small images by using a synchronization and mosaic function. The process involves:
1. Signal Input and Distribution: All input signals are connected to and switched by the primary processor (#0 LVP615). The same DVI outputs from #0 LVP615 are then looped to other processors (#1, #2, #3, and #4).
2. Image Cropping and Scaling: Each processor (#1 to #4) crops and scales a portion of the image according to predefined parameters. The total LED width is set to 3456 pixels, and the total height is 1920 pixels. Each unit covers a specific section of the display.
3. Mosaic Function: The processors are configured with the correct horizontal and vertical start positions (E.6 and E.7) to ensure that each unit only processes its assigned part of the image.
4. Synchronization: The mosaic function is enabled, and synchronization is turned on to ensure that all output images align correctly without delays or mismatches.
5. Automatic Calculation and Adjustment: The APP calculates and applies the parameters automatically, and manual adjustments can be made if needed.
By following these steps, the processors work together to output a seamless, synchronized image that spans across multiple LED screens, displaying the entire picture as a whole.
