Description The active video area is filled with multiple rows
of white single pixel dots. The dots define the
corners of what would appear to be square boxes
if all the connecting pixels were lit. The number
of rows of boxes and the number of boxes per
row depends on which version of the image is
selected and the screen aspect ratio of the currently
loaded format. The number in the image’s name
refers to the number of boxes that will be formed
along the minor axis for most aspect ratios. The
firmware calculates the ratio and then finds the
closest match from the following table.
