select the coefficient which determines the curve.

Values from 1.5 to . allow you to emphasise the detail of dark

images, but reduce overall contrast. Values higher than .

increase overall contrast, but reduce the detail of dark areas.
Value . typically yields pleasant, contrasty images.

OVERSCAN
Eliminates irregularities around the outer borders of the image.
Some less accurate sources may produce an image with
uneven borders; thanks to the overscan function these imper-
fections can be moved to outside the displayed area. For the
most common video sources, the overscanning value can be
in the range (no overscanning) to (maximum). The resulting
image always maintains the selected aspect irrespective of
the selected overscan value.

POSiTiON

Use this adjustment to position the image vertically and hori-

zontally.

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

centralized 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 AUTO button on the keypad. When this procedure is called

it is helpful to have a white or light coloured background on the

screen in the current picture.

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.

fREQUENCY/PhASE

These adjustment 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.
