movie screen, high-definition TV, etc. Using this setting when the 
input signal is a 16:9 image that has been squeezed to a 4:3 
image causes the image to be displayed with its normal 16:9 
aspect ratio.

Note

z When the input source is a component or an HDMI (DTV) 

signal with an aspect ratio of 16:9, the aspect ratio is fixed 
at 16:9. The aspect ratio setting cannot be changed in this 
case.

z For details about projection screen display conditions for 

different aspect ratio settings, see “Aspect Ratio Setting 
and Projection Image” (page 50).
