Appendix
Relationship between Aspect and Screen Aspect
This section describes the relationship between screen aspect (P55) and aspect (P58).
To project an image on the whole screen, select the most appropriate screen aspect ratio 
and aspect according to the aspect ratio of the screen and input signal type.
When Projecting an Image from a Computer
When the input signal is [ANALOG PC-1], [ANALOG PC-2], or [DIGITAL PC], select screen 
aspect and aspect as follows according to the resolution of the...

When Projecting an Image from Image Software
To project an image such as an image shot by a TV set, commercially available DVD software, or 
video camcorder (input signal [HDMI], [VIDEO], [S-VIDEO], [COMPONENT]), select an aspect ratio 
according to the image software format as follows. 
*1[Auto] cannot be selected for the aspect setting if the input signal type is [VIDEO].*2If an image from image software with aspect ratio of 16:9 is not projected...

An international standard of color repre-
sentation (color space) which is applied to 
general digital cameras, displays and oth-
ers. In this projector, if you select [sRGB] 
in the [Image mode] setting, the projector 
can project the best-quality image con-
forming to the sRGB Standard.

The aspect ratio is the ratio of the horizon-
tal (longer) dimension to the vertical 
(shorter) dimension of a screen. It is 
expressed as longer dimension : shorter 
dimension.
The following aspect ratio is normally 
used:
[4:3]
The aspect ratio widely accepted in the 
standard screen resolution, for example the 
traditional television screen and VGA (640 
x 480) and XGA (1024 x 768) in computer. 
The aspect ratio for this projector is 4:3.
[5:4]
This aspect ratio is used if you select the...

Number of pixels in each resolution
If you select SXGA+ (1400 dots x 1050 
dots) as the display resolution for the con-
necting computer, this projector can 
project high-resolution images. If your 
computer does not have the SXGA+ 
option, select the maximum resolution 
among the selectable options.

A memorized color is a color in our mem-
ory. The memorized color such as blue for 
the sky is more vivid than the real color, so 
you may feel colors of a projected image 
are dull. If such is the case, enable the 
memorized color correction function to 
make the colors close to the ones in our 
memory. You can enable the memorized 
color correction function in the image 
adjustment menu.

advanced user. You can adjust color bal-
ance and color level for...
