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 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.
•
2.5
sets the gamma to a 2.5 power law.
•
2.2
sets the gamma to a 2.2 power law.
•
Video
is similar to 2.2 gamma but differs in dark areas of the image to correspond to
the function that video cameras use to create images.
•
2.0
sets the gamma to a 2.0 power law.
•
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
or
to select 5500K, 6500K, 7500K, 9300K or Native. The default
setting, 6500K, is appropriate for most situations. Higher settings produce a “bluer”
picture; lower ones impart a reddish hue to the image. Select
Native
to disable white
point adjustment of the source signal.
