For use of settings in the column
"1 RgB"
, there are 9 available
preset settings of the white balance.
The default settings are:
STANDARD applies a certain white balance depending on the
standard selected in column
“1 RgB”
(Fig. 23)
HIGH - MEDIUM - LOW (default white balance levels);
NATIVE (the machines native white balance);
D75 - D65 - D50 - C standard CIE illuminants;
If the default white settings are not sufficient, you can adjust the
white balance manually.
Colour temperature can be adjusted by positioning the white
point within the CIE chromaticity diagram. The system permits
you to place the white point inside a grid positioned in the neu-
tral colour zone. Moving along the horizontal lines changes the
related colour temperature, with low temperatures on the right
(thus increasing the red content) and high temperatures on the
left of the graph (thus increasing the blue content). Points along
the yellow horizontal line represent the white balances on the
black body curve. The colour temperature along the vertical lines
SUBTITLES: this moves the image upwards, making room for the
subtitles to be seen.
PIXEL TO PIXEL: makes a pixel to pixel map of any image, without
introducing any alteration to adapt it to the screen. The image is
projected in the centre of the screen and if its horizontal and/or
vertical dimensions are smaller than the display, it is bordered
by vertical and/or horizontal black bands.
PERSONAL 1, 2, 3: can be used if none of the preset formats are
satisfactory. User formulas make it possible to continuously
adjust the picture size horizontally and vertically and hence
the aspect ratio.
The PULL DOWN menu, available for each aspect, permits you
to enable/disable the outlet to control the motorised curtains
used to block off the sides of 16:9 format projection screens
or the top and bottom of 4:3 format screens.
COLOUR TEMPERATURE

It is possible to define the position of the primary colours (red,
green and blue) using 5 preset settings (Fig.22).
The default settings are:
NATIVE (the projector’s native primary colours)
HDTV, EBU, SMPTE-C, primary colours defined by the standards
AUTO, mode that applies one of the standard settings described
above.
PC, mode available only if the projector has received Colour
Temperature instructions by connection to a PC and using Live
Colours Calibration software.
