9.4 Setp4: Output Settings

Output settings are divided into three cases:
First one: disable Scaling, i.e., the sizes of output image and input image are the same, and original
scale output is used. If the input resolution is smaller than the LED display in one direction, LED display
may not become bright in this direction; if the input resolution is greater than the LED display in one
direction, the input contents may not be displayed completely in this direction. This option is applicable
to the application scenarios requiring point-to-point display. Horizontal offset and vertical offset of images
can be set according to the needs, and at this time the displayed contents may move to the left or top at
the LED display.
