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.
• 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.
• NTSC: This is the standard format used mainly in the United States and Japan.
Gamma: Select Gamma from the Advanced menu to choose a DLP de-gamma curve. Used correctly, the Gamma con-
trol 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, lower
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.
• Video is similar to Film gamma but differs in dark areas of the image to correspond to the function that video cam-
eras 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 grayscale
accuracy.
DLP Frame Rate: Select DLP Frame Rate from the Advanced menu to choose the output frame rate. You can have the
projector 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: Select Color Gamut from the Advanced menu to select a color gamut (range) that may be different from
the default color gamut.
Each setting defines the precise hue of each primary (red, green and blue) and secondary (yellow, cyan and ma-
genta) color component used to generate the millions of colors produced in displays. Changing either or both of these
numbers changes the hue of the color and relocates the “triangle” for possible colors. For example, changing the x/y
coordinates for red moves the color closer to either orange or violet, which in turn affects all displayed colors having a
red component.
