Relationship between Aspect and Screen Aspect
This section describes the relationship between screen aspect (P60) and aspect 
(P66).
Select an optimum aspect ratio of the projected image (screen aspect) or an 
optimum screen mode (aspect) according to the aspect ratio of the screen, type of 
input image signal and so on for the projection to make best use of the screen size.
•If a computer image with an aspect ratio of 16:9 is not projected correctly when 
the setting is [Auto], select [16:9] as the screen aspect.
•For a 16:9 image with black borders at the top and bottom, such as a terrestrial 
broadcast movie, you can project the 16:9 image area so that it is projected on 
the entire screen by selecting [Zoom] in [Aspect].
There may be some cases that [Zoom] cannot be selected depending on the 
input signal and/or resolution.
•For keystone correction (P68), select an option other than [4:3 D. image shift] or 
[16:9 D. image shift] for [Screen aspect].
