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
when projecting
images that are neither 4:3 nor 16:10 ratio.
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.
