This menu features adjustments relating to picture position,
aspect ratio, magnification etc.
ASPECT
This adjustment allows you to change the dimensions and
aspect ratio (relationship between width and height) of the
displayed image. There are five preset aspects available and
three personalised aspects (with user-settable parameters). You
can select a different aspect for each source: the selected
aspect ratio will be automatically called the next time the
relative source is called.
You can also select the required aspect ratio by repeatedly
pressing the
key, or by pressing
and a numerical key
(1...8).
The following aspects are available:
NORMAL: projects the image occupying the full height of the
screen while maintaining the aspect ratio of the input signal.
When the input signal aspect ratio is 4: black vertical bands
are displayed on the right and left of the picture.
ANAMORPHIC: allows a 16:9 picture to be displayed correctly.
LETTERBOX: serves to display a 4: letterbox image (with source
signal having black bands above and below the picture) so that
it fills the 16:9 screen and maintains the correct aspect ratio.
PANORAMIC: stretches the 4: image, slightly cropping the upper
and lower parts. Panoramic is ideal for displaying a 4: image
on the 16:9 screen of the Display.
PIXEL TO PIXEL: displays the image as it is input without adapting
it to the screen. The image is projected in the centre of the
screen and if its horizontal and/or vertical dimensions are smal-
ler than the display, it is bounded by vertical and/or horizontal
black bands.
USER 1, , : when none of the preset formulas are suitable. The
User formulas are available, with the facility for continuous
horizontal and vertical adjustment of picture size.
SCREEN Control. If an appropriate screen-masking interface is
connected to the 1V output socket it is possible to re-frame
the screen to a variety of aspect ratios and screen sizes (please
refer to the screen manufacturer’s manual).
COLOR TEMPERATURE
Changes the colour balance of the image.
The colour temperature is adjusted by positioning the white dot
in the CIE chromaticity diagram. The system makes it possible
to position the white dot in a grid with 6 dots in the neutral
colour zone

Moving along the horizontal lines changes the correlated colour
temperature, with low temperatures on the right (where the red
component is increased) and high temperature on the left of
the graph (where the blue component is increased).
The dots in correspondence with the lower horizontal line
(Fig. 22)
represent the colours taken on the curve of the black body.
The colour temperature is constant along the vertical lines, but
deviates to a greater or lesser extent from the line of the black
body. This means that by selecting the dots at the top of the
graph there will be an increase in the green component. On
the contrary, by selecting elements at the bottom of the graph
there will be an increase in the purple component.
