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.

2.35 sets the gamma to a 2.35 power law.

2.2 sets the gamma to a 2.2 power law.

2.0 sets the gamma to a 2.0 power law.

1.8 sets the gamma to a 1.8 power law.

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.

DLP Frame Rate: Select DLP Frame Rate from the Advanced menu to choose the
output frame rate. You can have the LS-10i 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.

The Color Temperature setting is unavailable when you choose the
“PCE” C
olor Gamut setting (refer to Color Gamut, below).

If PIP is active, the LS-10i converts the PIP source frame rate to the
same frame rate as the main source.
