LED Screen Setup
This feature is available in VP-798ASV model. With this menu the user can define an area within the
output raster where the output scaled image will be positioned. This area should match exactly the
size of your LED wall. The image size is defined and positioned according to the right, left, top and
bottom edge settings.
The output image can be reduced to as few as 128x96 pixels. The adjustments are performed
horizontally in 4-pixel increments and vertically 1 line increment. If the source is 4K, the horizontal
increment is 8-pixels and vertically is 2 lines. A reset function is also provided to reset all parameters
to full output resolution.
In the example below, the unit is outputting a full resolution of 1920x1080, but the output image is
only present in the corner occupying an area of 1760x880. The LED processor/Sender box that
receives the signal, will only process this area (1760x880 pixels) and transmit it to the LED wall. The
rest of the 1920x1080 area will be ignored, and that is why is left black.
