Image Settings Menu
'
Use options in the Image
Settings menu to alter your
image without affecting its
size or position. Changes
made to the Image Settings
menu are applied
immediately and are saved
when you exit the menu
(press Exit or Menu ). Options
not available for the projector
model or source are disabled
and appear dim (grey).
Contrast
(
SHORT CUT:
Press
"Contrast" increases or decreases the perceived difference between light and dark
areas of your image (0-100). For best results, keep close to 50. If contrast is set too
high, the light parts of the image lose detail and clarity. If set too low, the light areas
will not be as bright as they could be and the overall image will be dim. For best
results, start with a low value and increase so that whites remain bright but are not
distorted or tinted, and that light areas do not become white (i.e., are "crushed").
NOTE: If the environment lighting changes, an adjustment of Gamma is
recommended (see below).
Brightness
(
SHORT CUT:
Press
"Brightness" increases or decreases the amount of black in the image (0-100). For
best results, keep close to 50. Start with a high value and decrease so that dark areas
do not become black (i.e., are "crushed"). Conversely, high brightness changes black
to dark gray, causing washed-out images.
Gamma
"Gamma" is a global setting that determines what gray shades are displayed between
minimum input (black) and maximum input (white) for all signals. A good gamma
setting helps to optimize blacks and whites while ensuring smooth transitions for the
"in-between" values utilized in other colors. Thus, unlike brightness and contrast
settings controls, the overall tone of your images can be lightened or darkened
without changing the extremes, and all images will be more vibrant while still
showing good detail in dark areas.
The normal gamma setting of 2.2 is correct for virtually all signals and conditions. If
excess ambient light washes out the image and it becomes difficult or impossible to
see details in dark areas, lower the gamma setting to compensate. This will improve
contrast while maintaining good details for blacks. Conversely, if the image is
washed out and unnatural, with excessive detail in black areas, increase the setting.
Again, good gamma improves contrast while maintaining good details for blacks.
