The aspect ratio is the ratio of the horizon-
tal dimension (width) to the vertical dimen-
sion (height) of a screen. It is expressed 
as "width : height."
The following aspect ratios are normally 
used in Computer or AV equipment.
[4:3]
The aspect ratio for SXGA+ (1400 x 1050) 
and XGA (1024 x 768) display resolution in 
PC or for the traditional television screen.
The aspect ratio for this projector is 4:3.
[5:4]
The aspect ratio for SXGA (1280 x 1024) 
display resolution.
[16:9]
The aspect ratio for the high resolution digital 
television or digital terrestrial broadcasting.
For the aspect ratio for movie screens, 
"vista vision size" and "cinema scope size", 
etc. are used.
"Vista vision size"
The aspect ratio close to 16:9. Select 
[Auto] or [16:9] for [Aspect]. The back 
belts are added at the top and bottom of 
the image.
"Cinema scope size"
The landscape-oriented aspect ratio of 
8:3. Select [Auto] or [16:9] for [Aspect]. 
The back belts are added at the top and 
bottom of the image.
A signal system in which an image is 
transmitted by being broken down the 
brightness signal (Y) and the color signal 
(C) into the B-Y color difference signal and 
the R-Y color difference signal. Its image 
quality is higher than that of the composite 
video. This system can project a better-
quality image as compared with the com-
posite signal system. Connect the compo-
nent video terminal on the AV equipment 
and the ANALOG PC-2/COMPONENT IN 
terminal on this projector with a compo-
nent cable. Select [COMPONENT] at pro-
jection.
To reproduce an image from an analog 
image signal, the process to accumulate 
image information at the appropriate tim-
ing with reference to the synchronization 
signal within the image signal is required. 
This process is called the tracking. This 
projector can display an image properly 
by automatically adjust the tracking with 
the auto PC adjustment function even if 
there is a small difference in the synchroni-
zation signal from an analog imaging 
device.
The number of dots (horizontal dots x ver-
tical dots) that can be displayed on the 
screen. It describes the fineness (informa-
tion amount) of the displayed image.
