13
(no overscanning) and 32 (maximum overscanning). The resulting
image always maintains the selected aspect irrespective of the
selected overscan value.
POSITION
Use this adjustment to position the image vertically and horizontally.
These parameters do not normally require adjustment because the
unit examines the input signal and automatically sets the most suita-
ble values. However, if the image is not perfectly centralised it may
prove useful to repeat the input signal analysis and the consequent
image positioning procedure. This automatic control procedure is
activated by pressing
AUTO
key on the remote control (or the key
on the front panel keypad when the OSD is not displayed). When
this procedure is called it is helpful to have a white or light coloured
background on the screen in the current picture.
FREQUENCY/PHASE
These adjustments, available for progressive signals and for signals
from a PC, ensure correspondence between the number of pixels
making up the signal and the number of pixels that make up the
image.
These parameters do not normally require adjustment because the
unit examines the input signal and automatically sets the most
suitable values. However, if the image appears disturbed (loss of
resolution within equidistant vertical bands or instability and lack of
sharpness on narrow vertical lines) it may help to prompt the unit to
repeat the input signal analysis and consequent determination of the
frequency and phase parameters. This automatic control procedure
is activated by pressing key
AUTO
on the remote control (or the
key on the front panel keypad when the OSD is not displayed).
If the automatic procedure fails to have the required effect, enter the
frequency and phase values manually and move sufficiently near to
the screen to observe the effects of the adjustments.
Y/C DELAY
In the case of Video and S-Video signals, it may be necessary to
correct horizontal colour misalignment within the image.
For a given video standard (e.g. PAL or NTSC) the stored value
does not normally require further fine-tuning, unless the source or
connection cable is changed.
PANORAMIC:
stretches the 4:3 image, slightly cropping the upper and
lower parts. Panoramic is ideal for displaying a 4:3 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 displayed in the centre of the screen and if its hori
-
zontal and/or vertical dimensions are smaller than the display, it is
bounded by vertical and/or horizontal black bands.
USER 1, 2, 3
: when none of the preset formulas are suitable, three
User controls are available, with the facility for continuous horizontal
and vertical adjustment of picture size.
COLOUR TEMPERATURE
Changes the colour balance of the image and is referred to the
colour temperature of white.
Colours can be adjusted towards the red end of the spectrum (low
colour temperature values - expressed in degrees Kelvin) or the
blue end (high values). Colour temperature can be selected with
three preset values:
HIGH, MEDIUM
and
LOW
. In addition, a
USER
setting
is provided in which the user can set the white point by making
separate adjustments for Red, Green and Blue.
Generally, the
HIGH
value is more suitable for displaying graphic
images, while
MEDIUM
and
LOW
values are preferable for video
images.
GAMMA CORRECTION
Determines the response to the grey scale, emphasising or atte-
nuating the different grades of brightness (blacks, dark, medium,
light grey, whites) in the image. The
GRAPHIC
setting is more suitable
for computer images, while the
VIDEO
and
FILM
settings are more
suitable for video images.
OVERSCAN
Eliminates irregularities around the outer borders of the image.
Certain relatively inaccurate sources can produce an image with
more or less pronounced irregularities around the outer edges;
thanks to the overscan function these imperfections can be moved
to outside the displayed area. Overscan values can be between 0
