							Operation 39
Selecting the aspect ratio
The aspect ratio is the ratio of the picture width to the 
picture height. Most analog TV and computers are in 
4:3 ratio, and digital TV and DVDs are usually in 16:9 
ratio.
With the advent of digital signal processing, digital 
display devices like this projector can dynamically 
stretch and scale the picture output to a different aspect 
than that of the picture input source.
To change the projected picture ratio (no matter what 
aspect the source is):
• Using the remote control
1. Press ASPECT to show the current setting.
2. Press ASPECT repeatedly to select an aspect ratio 
to suit the format of the video signal and your 
display requirements.
• Using the OSD menu
1. Press MENU and then press  /  until the 
Display menu is highlighted.
2. Press  to highlight Aspect Ratio.
3. Press  /  to select an aspect ratio to suit the 
format of the video signal and your display 
requirements.
Shifting the picture around the black areas
If there are unused resolutions along the top and 
bottom sides, you can shift the pictures vertically until 
it reaches the top or bottom of the unused areas.
To shift the picture:
1. In the Display menu, press   or   to highlight 
Digital Screen Shift.
2. Press   or   to adjust the vertical position of 
the projected areas.
About the aspect ratio
1.4:3: Scales a picture so that it is displayed in the 
center of the screen with a 4:3 aspect ratio. This is 
most suitable for 4:3 pictures like computer 
monitors, standard definition TV and 4:3 aspect 
DVD movies, as it displays them without aspect 
alteration.

							40 Operation2.Anamorphic: Scales a picture so that it is displayed 
in the center of the screen using 1280 x 720 pixels. 
This may alter the projected aspect, depending 
upon the original aspect of the source image. 
Anamorphic is most suitable for images which are 
already in a 16:9 aspect, like high definition TV, as it 
displays them without aspect alteration.
3.Fill: Resizes the picture to the full projection area. 
1280 x 768 pixel is used without maintaining the 
original aspect ratio. This is most suitable for 15:9 
pictures.
4.Letter Box: Scales a picture to fit the projector’s 
native resolution in its horizontal width and resize 
the picture’s height to the 3/4 of the projection 
width. 1280 x 960 pixels are used in this projection. 
This may produce a picture greater in height than 
can be displayed, so part of the picture is lost (not 
displayed) along the top and bottom edges of the 
projection. This is suitable for the display of movies 
which are presented in letter box format (with black 
bars on the top and bottom).
5.Wide: Stretches the picture horizontally in a non-
linear manner, that is, the edges of the picture are 
stretched more than the center of the picture to 
prevent distortion of the central part of the picture. 
This is suitable for occasions where you want to 
stretch the width of a 4:3 aspect picture to the width 
of a 16:9 aspect screen. It does not alter the height. 
Some widescreen movies have been produced with 
their width squashed down to the width of a 4:3 
aspect, and are best viewed when restretched back 
to their original width using this setting. 
6.Real: For input sources with lower resolutions than 
1280 x 768, the projected picture will display 
smaller than if resized to full screen. 
If the input source is with higher resolution than 
1280 x 768, the picture will be resized 
proportionally until it fits the width or height of the 
projection.
