The menus are grouped by usage: 
The Picture menu provides image adjustments. 
The Settings menu provides set-up type adjustments that are not changed often. 
The About menu provides a read-
only display of information about 
the projector and source.  
Certain menu items may be hidden 
until a particular source is 
connected. For example, Tint is 
only available for NTSC video 
sources and will be hidden when 
other sources are active. Other 
menu items may be grayed out when they are not available....

Native: this mode bypasses the internal scaler, displaying the image with no r\
esizing.  
Since the native resolution is 1280x720 and 4x3 video images are approximately 
640x480, 4x3 images will always be smaller than the display and will be \
centered in the 
display.  Computer images 1024x768 or smaller will also be centered in t\
he display.  If a 
16x9 video source or a 1280x1024 or larger computer source is viewed, it\
 will display up 
to 1280 pixels and 720 lines from the center of the...
