OPERATION
Contrast
(SHORT CUT: Press and adjust the slidebar.)
"Contrast" increases or decreases the perceived difference between light and dark areas of your
image (0-100). 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 it may be difficult to distinguish
between foreground and background information. Adjust so that whites remain bright but not dis-
torted or tinted. For best results, keep close to 50.
NOTE: If environment lighting changes, it may be necessary to re-adjust both options.
Brightness
(SHORT CUT: Press and adjust the slidebar.)
"Brightness" increases or decreases the amount of perceived light in the dark part of the image
(0-100). If video or data is displayed with a black background, adjust until the background just
changes from black to very dark gray. For best results, keep close to 50.
Sharpness
(SHORT CUT: Press and adjust the slidebar.)
“Detail” adjusts the sharpness of the video image. Use or until the display is as sharp
as possible, keeping in mind that any level of detail above 3 (default) will increase the level of
detail as well as introduce some level of noise in the image. Set below 3 to filter the signal and
remove noise from a noisy source. Keep at 3 to apply no detail. NOTE: DETAIL is not available
in the RGB mode.
Signal
Type
This option determines how the color components of an input signal
are decoded for accurate color in the display. Selecting a color balance
option is useful only for analog signals connected to INPUT 1 or
INPUT 2. Although the color space for such a signal is automatically
determined by the projector, in some circumstances you may wish to
override this and manually set a different color space.
NOTE: For digital signals or for signals connected to INPUT 3 or INPUT 4, the color space
function is entirely automatic and the pull-down list disabled.
The current color space appears in the Image Adjustments menu. Press to select a different
option:
Select RGB unless you are using component video at INPUT 1 or 2.
Select Component Video (video) if you are using a standard definition televised sig-
nal (SDTV)
Select Component HDTV (HDTV) if you are using a high definition decoder
(HDTV).
