Video Standard: Select Video Standard from the ADVANCED menu to specify the color system for composite
video or S-Video input signals.
Different countries use different formats for video signals. Select the appropriate Video Standard for your region:
Auto: The color systems are automatically identified and the format is set accordingly.
NTSC: This is the standard format used mainly in the United States and Japan.
PAL: This is the standard used in Europe, Australia and many other parts of the world, typically with a 50Hz
frame rate.
SECAM: This is a standard format used mainly in France and Russia.
Gamma: Select Gamma from the ADVANCED menu to choose a DLP de-gamma curve. Used correctly, the
Gamma control can improve contrast while maintaining good details for blacks and whites.
If excess ambient light washes out the image and it becomes difficult or impossible to see details in dark areas, low-
er the gamma setting to compensate. This improves 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.
CRT sets the gamma to 2.5.
Film sets the gamma to 2.2.
Cinema is similar to Film gamma but differs in dark areas of the image to correspond to the function that video
cameras use to create images.
Bright sets the gamma to 2.0.
Graphics should only be used for computer presentations that require increased brightness at the cost of gray-
scale accuracy.
Color Temperature: Select to set the projector’s color temperature. Range: Warm, Standard (default), Cool, Cooler.
DLP Frame Rate: Select DLP Frame Rate from the ADVANCED menu to choose the output frame rate. You can
have the H9080FD automatically determine the optimum frame rate, or you can force it to use a specific frame rate.
The default setting, Auto, frame locks to the main source if it has a vertical refresh rate of between 48 and 62Hz.
Vertical refresh rates of from 24 to 31Hz are doubled. Frame rates between 31 and 48Hz and greater than 62Hz are
converted to 60Hz.
Select 48Hz to force the output frame rate to 48Hz. Use this setting to eliminate 2:3 pull-down judder with 60Hz
film-based sources.
50Hz and 60Hz force the output frame rate to 50Hz and 60Hz respectively.
Color Gamut: Press the or buttons to select the Golor Gamut values. The default setting is Auto.
BrilliantColor: Press the or buttons to enable or disable BrilliantColor.
Dynamic Iris: Press the or buttons to enable or disable Dynamic Iris.
Adaptive Contrast: Adaptive Contrast enhancement expands the light and dark portions of an output image ac-
cording to the mean luminance of the input image.
