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:
