When Projecting an Image from Image Software
To project an image such as an image shot by a TV set, commercially available DVD software,
or video camcorder (input signal [HDMI (SX80)], [VIDEO], [S-VIDEO (SX80)], [COMPONENT]),
select an aspect ratio according to the image software format as follows.
*1
[Auto] cannot be selected for the aspect setting if the input signal type is [VIDEO].
*2
If an image from image software with aspect ratio of 16:9 is not projected correctly, select [16:9]
as screen aspect.
*3
If you project the 16:9 image with black borders at top and bottom such as in the terrestrial movie
broadcasting, you can project the 16:9 image fully on the screen by selecting [Zoom] in [Aspect].
[Zoom] is available when [16:9] or [16:9 D. image shift] is selected for the screen aspect and
[HDMI (480p)(SX80)], [COMPONENT (480p, 480i)], [VIDEO] or [S-VIDEO (SX80)] is selected for
the input signal.

To perform keystone adjustment ( P58 ), select [4:3] or [16:9] for [Screen aspect].
