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
resolution such as SXGA (1280 x 1024) in
computer. The shorter dimension in [5:4]
is a little longer than that in [4:3].
An image is displayed with proper screen
aspect if you select [Auto] or [True size]
for [Screen aspect]; however, the margins
are displayed on both sides of the screen.
[16:9]
The aspect ratio for the high definition or
wide-screen. WXGA (1280 x 768 and 1360 x
768) is used as the aspect ratio close to 16:9
for the wide screen monitor in computer. An
image with aspect ratio of 16:9 is properly
displayed if you select [Auto] for [Aspect];
however, the margins are displayed at the
top and bottom of the screen.
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 used to send a color sig-
nal (C) with it divided into a B-Y color dif-
ference signal and an R-Y color difference
signal. 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 a
computer is called “resolution of display”.
Resolution indicates the size of the display
area (amount of information).
