Each of these has 9 available preset settings of the white

balance. To access the white balance adjustment menu it is

necessary to press key 2 on the remote control.

The default settings are:

STANDARD applies a certain white balance depending on

the standard selected in column “1 RGB”:

HIGH - MEDIUM - LOW (default white balance levels);

NATIVE (the machine's native white balance);

D75 - D65 - D50 - C standard CIE illuminants;

If the default white balance settings are not sufﬁcient, you

can adjust the white balance manually. To manually adjust-

ment the white balance, go to the Personal item and press

3. The 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 tempera-

tures 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 lowest 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 enable 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.).By choosing User you can

deﬁne your own curve. You can thus select the coefﬁcient

which determines the curve.

Coefﬁcient values from 1.5 to 2.2 allow you to emphasise

the detail of dark images, while reducing overall contrast.

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.
