‘Aspect adjust’ = ‘Advanced’
This item allows the independent setting of the horizontal and vertical zoom values.
The third number (1.333 in the example) is the Aspect Ratio resulting from the
adjustments, which is automatically calculated for you based on the incoming
resolution and the H & V Zoom values.
Most resolutions are 4:3 ratio, thus the third number will be 1.333 (4 divided by 3).
Another common aspect ratio is 16:9 (16 divided by 9 = 1.777). PAL and NTSC
inputs are physically 4:3 on your video monitor, but their actual pixel/line ratios are
different and so will not display as 1.333.
This item allows the setting of different Horizontal and Vertical ‘shrink’ sizes. The
third number (1.333 in the example) is the Aspect Ratio resulting from the
adjustments, which is automatically calculated for you based on the output resolution
(the actual pixels & lines, not your physical screen size) and the H & V Shrink values.
Most resolutions are 4:3 ratio, thus the third number will be 1.333 (4 divided by 3).
Another common aspect ratio is 16:9 (16 divided by 9 = 1.777). Therefore, to
convert your 4:3 output into a 16:9 output, reduce the vertical (V) Shrink value to
75% and this will simulate a 16:9 output. PAL and NTSC inputs are physically 4:3 on
your video monitor, but their actual pixel/line ratios are different and so will not
display as 1.333.
