ENGLISH

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

neutral 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 lower horizontal line represent the colours on

the black body curve.

The colour temperature along the vertical lines is constant

but differs to a lesser or higher degree from the black body

curve. This means that by selecting the points on the higher

part of the graph you will increase the green component.

On the contrary, by selecting points in the lower part of the

graph, the purple component increases.

GAMMA CORRECTION

Determines the systems response to the grey scale, em-

phasising or attenuating the different grades of brightness

(blacks, dark, medium and light greys, whites) in the pro-

jected image.

The projector has a range of gamma functions which en-

able you to display any image to the best effect for the type

of video source, the ambient lighting and your subjective

preferences.

There are 3 sets of gamma curves: Standard (ST), Enhanced

SIM2 (EN) and Graphics (GR). The Standard curve has been

deﬁned for general use, and is set for camcorders, digital

cameras, and for viewing ﬁlms or photos from your PC.

The Enhanced set is suitable for watching movies. The

Graphics set is suited to displaying synthetic graphics (PC,

CAD, PC presentations, etc.).

Values higher than 2.2 increase overall contrast, but reduce

the detail of dark areas. For the most common video sources,

if you set the parameter to 2.2, you will obtain pleasant and

well-contrasted 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

imperfections can be moved outside the projected area.

POSITION

Use this adjustment to position the image vertically and

horizontally. These parameters do not normally require ad-

justment because the system checks the input signal and

automatically sets the most suitable values. However, if the

image is not perfectly centred it may prove useful to make the

system repeat the input signal analysis and image position-

ing, requesting the automatic control procedure with button

A on the remote control. When this procedure is requested

it is helpful to have a white or light coloured background in

the current picture on the screen.

Y/C DELAY

Where Video and S-Video signals are concerned, 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 adjustment, unless the source or connection cable

is changed.
