Selecting the aspect ratio

The 'aspect ratio' is the ratio of the image width to the image height.

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 signal.

To change the projected image ratio (no matter what aspect the source is):

• Using the remote control

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

In the pictures below, the black portions are inactive areas and the white portions are active areas. OSD menus can be displayed on those unused black areas.

1.

Auto: Scales an image proportionally to fit the

 

 

 

projector's native resolution in its horizontal or

 

 

vertical width. This is suitable for the incoming

 

 

image which is neither in 4:3 nor 16:9 and you

want to make most use of the screen without

 

 

altering the image's aspect ratio.

 

 

 

 

16:9 picture

2.Real: The image is projected as its original resolution, and resized to fit within the display area. For input signals with lower resolutions, the projected image will display smaller than if resized to full screen. You could adjust the zoom setting or move the projector towards the screen to increase the image size if necessary. You may also need to refocus the projector after making these adjusents.

3.4:3: Scales an image so that it is displayed in the center of the screen with a 4:3 aspect ratio. This is most suitable for 4:3 images like computer monitors, standard definition TV and 4:3 aspect DVD movies, as it displays them without aspect alteration.
