PICTURE
This menu features the adjustments related to picture quality.
Adjustments that are not available for a given input do not
appear on the menu. Table 1 summarises the adjustments avai-
lable for each input. For a complete overview of the on-screen
menus, consult the 'On screen menu layout' in the "Additional
Information" section.
BRIGHTNESS
Use this control to adjust the image's black level without
affecting white areas. Increasing the value will give more detail
in darker parts of the picture. For correct adjustment it may pro-
ve useful to display the signal relative to the grey scale within
which the black level and the level immediately above it must

be separately identifiable. Alternatively use a scene composed
of black objects alongside other dark coloured objects.
CONTRAST
Use this control to adjust the image's black level without af-
fecting white areas.To ensure correct adjustment, it may prove
useful to display the signal relative to the grey scale, within
which the white level and the level immediately below it must
be separately identifiable. Alternatively use a scene composed
of well-lit white objects surrounded by light coloured objects
with lower level lighting.
COLOR
This control (also called Saturation) increases or decreases
the picture colour intensity. When set to zero, colour images
will be shown in black and white. Increasing the value, try to
find the point at which the colours look natural: suitable referen-
ces include skin tones and grass in landscape shots.
TINT
Controls the purity of the colours. Basically determines the
red-green ratio of the picture.
Reducing the value will boost the red contents of the pictu-
re, increasing the value will boost the green tones. For this
adjustment use skin tones or a test pattern image with colour
bars as a reference.
SHARPNESS
Use this adjustment to increase and decrease the level of
picture detail.
When the sharpness value is reduced the image details
appear less pronounced, while increasing the value raises
image definition, making the outline of objects sharper.
Note that an excessively high value may result in a 'noisy' picture
and the edges of objects may be unnaturally defined.
SHARPNESS MODE
This allows you to select the type of processing associated
with sharpness adjustment. In the case of a progressive or in-
terlaced video signal VIDEO mode is advisable; with PC graphic
signals use GRAPHIC MODE.
FILTER
This allows you to select the mode in which the input signal
is processed. Selecting the most appropriate value for a given
input signal ensures the best horizontal and vertical definition
and makes the picture sharper.
