mainly in the United States and Japan.
• PAL: (Phase Alternation by Line): This is the standard used in Europe, Australia and
many other parts of the world, typically with a 50Hz frame rate.
• SECAM (Sequential Color With Memory): 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 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, 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 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 grayscale accuracy.
Color temperature:
Color temperature defines the “color of gray;” that is, adjusts the 75%
white point to various color points.
To choose a color temperature setting, select Color Temperature from the Advanced menu.
Then, press
◄
►
to select 5500K, 6500K, 7500K, 9300K. The default setting, 6500K, is
appropriate for most situations. Higher settings produce a “bluer picture; lower ones impart
a reddish hue to the image.
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 magenta) 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.

◦
SMPTE C for NTSC, 480i and 480p sources.
◦
