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: DVD player 720p signal 720 active scan lines 750 total scan lines 720 1280 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). DVD player 575p signal 576 768 4:3 aspect ratio 720 960 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.
