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.
This function is only available when a Video signal is selected
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 remote control
Press one of the aspect ratio keys to suit the for mat 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.

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 w ith
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.
