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 entering DISPLAY > Aspect Ratio. 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 to fit the projector’s native resolution(4:3).
This is suitable when you want to make most use of the screen
2.Native: The image is projected as its original resolution, and
resized to fit within the display area proportionally. 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 fit for 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 14 and "Obtaining a preferred projected image size" on page 8 for details.
