Appendix
The aspect ratio is the ratio of the horizon-
tal dimension (width) to the vertical
dimension (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.
[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 broad-
casting.
[16:10]
The aspect ratio for the wide PC screen
such as WUGA (1920 x 1200), WSXGA
(1440 x 900), and WSXGA+ (1680 x 1050).
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 into the
brightness signal (Y), color signal (C), B-Y
color difference signal, and R-Y color dif-
ference signal. Its image quality is higher
than that of the composite video. This sys-
tem can project a better-quality image as
compared with the composite signal sys-
tem. Connect the component video termi-
nal on the AV equipment and the ANALOG
PC-2/COMPONENT IN terminal on this
projector with a component cable. Select
[COMPONENT] at projection.
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.
