Values from 1.5 to 2.2 allow you to emphasise the detail of dark
images, but reduce overall contrast. Values higher than 2.2
increase overall contrast, but reduce the detail of dark areas.
For the most common video sources, the overscanning value
can be in the range (no overscanning) to 32 (maximum). The
resulting image always maintains the selected aspect irrespec-
tive of the selected overscan value.
POSiTiON
Use this adjustment to position the image vertically and horizon-
tally. Determines the aspect ratio of the projected image.
These parameters do not normally require adjustment because
the system checks the input signal and automatically sets the
most suitable values. However, if the image is not perfectly
centralised it may prove useful to request the system to repeat
the input signal analysis and image positioning, calling the au-
tomatic control procedure with button A on the remote control
or the AUTObutton on the keypad. When this procedure is called
it is helpful to have a while or light coloured background on the
screen in the current picture.
Frequency/phase
These adjustments, available for progressive signals and for si-
gnals from a PC, ensure correspondence between the number
of pixels making up the signal and the number of pixels that
make up the projected image.
These parameters do not normally require adjustment because
the system checks the input signal and automatically sets the
most suitable values. If however the image is disturbed (loss of
resolution between equidistant vertical bands or instability and
lack of detail in thin vertical lines) it may help to ask the system
to rerun the input signal analysis and set the best parameters
by calling up the automatic adjustment function with A on the
remote control or AUTO on the keypad.
If the automatic procedure fails to have the required effect,
enter the frequency and phase values manually and ap-
proach the screen sufficiently to observe the effects of the
adjustments.
OVERSCAN
Eliminates irregularities around the outer borders of the im-
age.
Some less accurate sources may produce an image with
uneven borders; thanks to the overscan function these im-
perfections can be moved to outside the displayed area. Il
parameter to 2.2, typically yields pleasant, contrasty images.
Y/C DELAY
In the case of Video and S-Video signals, it may be necessary
to correct horizontal colour misalignment within the projected
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 has changed.
SETUP
The setup menu contains less frequently used adjustments that
may be required during installation (e.g. On Screen Display
language selection or the display of Test Patterns).
ORiENTATiON
Reverse the image vertically and horizontally to best fit the
installation: i.e. desktop front, ceiling front, desktop rear and
ceiling rear (Fig.25).
