numbers on the projector's input panel. The last two, 7 and 8, require the Dual

you reach the desired level of white—for best results, start low and increase so that
whites remain bright but are not distorted or tinted, and that light areas do not
become white (i.e., "crushed"). Conversely, low contrast causes dim images. See 3.7
Adjusting the Image (Image Settings subsection).
Brightness
Bright
Press to increase or decrease the amount of black in the image. Use
Bright
keys until you reach the desired level of black—for best results, start high and
decrease so that dark areas do not become black (i.e., "crushed"). Conversely, overly
high brightness changes black to dark gray, causing washed-out images. See 3.7
Adjusting the Image (Image Settings subsection).
Gamma
Gamma
"Gamma" determines what gray shades are displayed between minimum output
(black) and maximum output (white) for a given signal. The proper setting helps
maintain optimized blacks and whites while ensuring a smooth transition for the "in-
between" values utilized in colors. Thus, unlike brightness and contrast settings
controls, the overall tone of your images can be lightened or darkened without
changing the two extremes, and all images will be more vibrant yet with good detail
in dark areas.
The normal Gamma Table setting of 2.5 is correct for most 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. Conversely, if the
image is washed out and unnatural, with excessive detail in black areas, increase the
