For the items that have “Signal Specific” in the “Setting Unit” column of the above table, the setting is 
saved for the specific type of signal (XGA/60Hz, SXGA/60Hz, etc.) that is being input when the setting 
is performed, and not for a specific input source.

Keystone 
Correction
RCVHDWUNSingle Use this sub-menu to perform vertical keystone correction of the 
projected image.
Aspect Ratio
RCVHDSource 
SpecificUse this sub-menu to select an aspect ratio setting for the 
projected image.
Input Source: RGB or HDMI (PC)
Normal*:
Projects at the projector’s maximum possible size while 
maintaining the input signal aspect ratio.
Full:
Projects at the projector’s maximum possible size by enlarging 
or reducing the input signal.
4:3 (XJ-A241/XJ-A246/XJ-A251/XJ-A256 only):
Regardless of the input signal aspect ratio, the image is always 
resized to an aspect ratio of 4:3 for projection.
True (XJ-A241/XJ-A246/XJ-A251/XJ-A256 only):
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.
Input Source: Video, Component or HDMI 
(DTV)
Normal*:
Projects at the projector’s maximum possible size while 
maintaining the input signal aspect ratio.
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 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.
4:3 (XJ-A241/XJ-A246/XJ-A251/XJ-A256 only):
Regardless of the input signal aspect ratio, the image is always 
resized to an aspect ratio of 4:3 for projection.
Letter Box (XJ-A241/XJ-A246/XJ-A251/XJ-A256 only):
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.
NotezWhen 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.
zFor details about projection screen display conditions for 
different aspect ratio settings, see “Aspect Ratio Setting 
and Projection Image” (page 51).
