projected image.

*:

Projects at the projector’s maximum possible size while 
maintaining the input signal aspect ratio.

Projects at the projector’s maximum possible size by enlarging 
or reducing the input signal.

Projects the input signal at its actual size (1 input source dot 
equal to one projector output pixel dot) in the center of the 
projector’s projection screen. If the input signal resolution 
exceeds the projector’s output resolution, the excess is cut off.

*:

Projects at the projector’s maximum possible size while 
maintaining the input signal aspect ratio.

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 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.

This will resize the image horizontally to 1280 dots and project 
800 vertical dots of the center of the image, maintaining the 
aspect ratio of the input signal.

Note

 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.

 When projecting while “True” is selected as the aspect 

ratio setting for an RGB signal with a resolution that is 
less than SVGA, the image is enlarged to SVGA and 
projected.

 For details about projection screen display conditions for 

different aspect ratio settings, see “Aspect Ratio Setting 
and Projection Image” (page 44).

Important!

Note that enlarging or reducing the size of an image for 
commercial purposes or public presentation may infringe on
