Aspect Ratio

Source 
Specific

Use this sub-menu to select one of the following aspect 
ratios for the projected image.

*:

This setting specifies a 4:3 aspect ratio, which is the 
same as a standard television.

16:9:
This setting specifies a 16:9 aspect ratio, which is the 
same as a movie screen, high-definition TV, etc. Using 
this setting when the input source image is a 16:9 image 
that has been squeezed to a 4:3 image causes the 
image to be projected with its normal 16:9 aspect ratio.

When the input source is a component signal with 
an aspect ratio of 16:9, the aspect ratio switches 
automatically to 16:9. When this happens, the 
aspect ratio cannot be changed using this setting.
