Generally, the HIGH value is more suitable for displaying graphic
images, MEDIUM and LOW for video images.
We recommend that only expert users make these adjustments
since there is a risk of obtaining results that could lower the
quality of the projected image.
GAMMA CORRECTION
Determines the system’s response to the “grey scale,” placing
more or less emphasis on the various tones of brightness (black,
dark grey, medium, light grey, white) making up the projected
image.
The GRAPHIC value is more suitable for computer images, while
the FILM and VIDEO values are more suitable for video images.
Y/C DELAY
In the case of Video and S-Video signals, it may be necessary
to horizontally align the colours within the borders of the various
objects making up 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 the cable connection has
changed.
MAGNIFICATION
Allows you to magnify the image (electronic zoom) and select
the area to be enlarged.
The level of magnification is adjusted in Zoom mode (identified
by a magnifying glass in the centre of the image) using the keys
and
. The area of the image to be enlarged is selected in Pan
mode (symbol in the centre of the image) using the arrow keys
and

It is possible to switch from one mode to the other with the remote
control by pressing

one of the 9 predefined positions.
OSD BACKGROUND
Determines the type of background for the On Screen Display.
OSD TIMEOUT
Adjusts the amount of time before the On Screen Display is
automatically erased from the projected image.

•
Make sure the selected input is connected to a video signal
or graphic source and that that source is working.
•
Check the integrity of the cables used to connect the system
to the various sources.
•
Make sure the video or graphic signals supplied by the source
are compatible with the system’s technical specifications and,
in particular, with those of the selected input.
