Adjustments move only the right side of the image; outwards to make the
image wider, or inwards to make the image narrower.
N A setting increment widens the picture out to the right, and a setting decrement
narrows the picture in from the right. The vertical dimension does not change,
and the image remains anchored at the active pixel horizontal and vertical start
point, at the top left of the display.
Use the right front panel encoder ( {
) to adjust the image vertical size.
N A setting increment makes the picture taller, and a setting decrement shrinks the
picture. The horizontal dimension does not change.
With ISM RGB boards, the image remains anchored at the active pixel
horizontal and vertical start point. The vertical size adjustment moves only the
bottom of the image, moving it down to make the image taller or up to make the
image shorter
