About the aspect ratio
1. Anamorphic (ANA): Scales an image so that it is displayed in the center of the screen with a 16:9 aspect ratio. This setting stretches and resizes linearly, except that it treats the vertical and horizontal dimensions independently. It stretches the
height of the source image until it reaches the full projected height, and stretches the width of the source image until it reaches the full projected width. 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.
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.Letter Box (LB): 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. 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).
4. Wide: Stretches the picture horizontally in a
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.
5.Real: This setting displays the image in a
mapping without alteration or resize in the centre of the projection. This is most suitable for use with PC and RGBHD 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.
