Extended scaling controls
The ‘Aspect adjust’ parameter is used to change the way that scaling of windows is controlled. By default,
it is set to ‘Simple’ which allows basic control of the window zoom and shrink sizes and positions – enough
for simple tasks.
In ‘Advanced’ mode, it allows the horizontal (H) and vertical (V) components of the Zoom and Shrink
functions to be adjusted independently, thus allowing custom aspect ratios to be created, or to convert
from one aspect ratio to another.
In ‘Pixel’ mode, the user has direct access to pixel and line-accurate scaling functions. This lets the user
specify the exact co-ordinates and size of the source image (within the video source), and the position and
size of where this is placed in the output video signal.
The table below summarizes the different menu items in the different modes – the ‘Simple’ items have
already been described earlier in this section, so only the ‘Advanced’ and ‘Pixel’ ones that are different
(highlighted in bold) will be detailed here.

‘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.
