Setting 3D Comb Filter

This feature separates composite signal to Y (brightness) signal and C 
(color) signal, and can help produce clearer and sharper images with 
correct colors in place.

Selecting the aspect ratio

The "aspect ratio" is the ratio of the image width to the image height. Digital TV is usually in 16:9 ratio, 
which is the default for this projector, 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. 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.
