70 Specifications

Image Size and Aspect Ratio Settings

Digital and analog picture formats include a portion of the image that is not normally visible

on the screen. For example, a 720p digital video signal includes 750 total scan lines, of which

only 720 are active. The projector displays the active picture area, as shown below:

Note: Using the Output Scaling function, you can set the projector to display both the hidden and

visible parts of the image. You can also use the Position and Zoom Caption options to view the

picture’s hidden edges (see page 36).

When the source signal’s resolution differs from the projector’s native resolution (1280 × 720

pixels) or aspect ratio (16:9), the image has to be resized to fit optimally on the screen. In

many cases, the projector can automatically resize the picture when Auto is selected as the

Aspect setting (see page 23).

If necessary, you can select a different Aspect setting to optimize the image. The resolution at

which the image displays for a given setting depends on the currently active picture source, as

listed in the following tables.
