Selecting the aspect ratio
The "aspect ratio" is the ratio of the image width to the image height. The default for this projector is
16:10 while digital TV is usually in 16:9 ratio, and most analog TV signals and DVDs are in 4:3 ratio.
With the advent of digital signal processing, digital display devices like this projector can dynamically
stretch and scale the image output to a different aspect than that of the image input source. Images can
be stretched in a linear manner so the whole of the image is stretched equally, or non-linearly, which
distorts the image.
To change the projected picture ratio (no matter what aspect
the source is):
• Using the control button
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/EXIT 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.
About the aspect ratio
1. Auto: Scales a picture proportionally to fit the projector's native
resolution in its horizontal or vertical width. This makes the most use of
the screen and maintains the aspect ratio of a picture.
2. 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.
3. 16:9:
Scales a picture so that it is displayed in the center of the screen with
a 16:9 aspect ratio. This is most suitable for 16:9 pictures like LCD
monitors, high definition TV and 16:9 aspect DVD movies, as it displays
them without aspect alteration.
4. 16:10:
Scales a picture so that it is displayed in the center of the screen
with a 16:10 aspect ratio. This is most suitable for images which are already
in a 16:10 aspect, as it displays them without aspect alteration.
5. Real: This setting displays the image in a one-to-one pixel mapping
without alteration or resize in the center of the projection. This is most
suitable for use with PC source inputs.
• The black portions are inactive areas and the white portions are active
areas.
• OSD menus can be displayed on those unused black areas.
