Selecting the aspect ratio

The 'aspect ratio' is the ratio of the image width to the image height. Most analog TV and computers are in 4:3 ratio, which is the default for this projector, and digital TV and DVDs are usually in 16:9 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.

You can change the projected image ratio (no matter what aspect the source is) by pressing ASPECT on the remote control or in the DISPLAY > Aspect Ratio menu. Select an aspect ratio to suit the format of the video signal and your display requirements. There are four aspect ratios available:

In the pictures below, the black portions are inactive areas and the white portions are active areas.

1.Auto: Scales an image proportionally to fit the projector's native

resolution in its horizontal 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.

2.Actual Size: The image is projected as its original resolution, with no

pixel conversion. 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 adjustments.

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.

4.16:9: Scales an image so that it is displayed in the center of the screen

with a 16:9 aspect ratio. This is most suitable for images which are already in a 16:9 aspect, like high definition TV, as it displays them without aspect alteration.

16:9 aspect ratio is only sourced through the Component Video input when

being fed an appropriate 16:9 aspect signal. See "Connecting a Component Video source device" on page 27 and "Obtaining a preferred projected image size" on page 19 for details.
