screen. For video sources, you can use the Resize option to select from among
four different re-sizing options. The default is Standard, which resizes the
image from its original version to fit a standard 4 x 3 aspect ratio screen.
Widescreen Letterbox
preserves the 16 x 9 aspect ratio of the original theater
version, but the image is placed in a 4 x 3 space, so black bars are displayed
at the top and bottom of the image. Enhanced Widescreen also preserves the
aspect ratio of the original theater version and is designed to be used with
content that is enhanced for wide-screen TVs. This option yields more detail
than Widescreen Letterbox. Native reduces the Standard size to match the
height of Enhanced Widescreen.
Manual sync
The projector adjusts signal synchronization automatically for most
computers. But if the projected computer image looks fuzzy or streaked, try
turning Auto Image off and then on again. If the image still looks bad, try
adjusting the signal synchronization manually:
1.
Turn Auto Image off.
2.
Highlight Manual sync, and then press the left or right navigation button
repeatedly until the image is sharp and free of streaks.
Manual tracking
The projector adjusts tracking automatically to match the video signal from
your computer. However, if the image has evenly spaced, fuzzy, vertical lines
or if the projected image is too wide or too narrow for the screen, try turning
Auto Image
off and on again. If the image is still bad, try adjusting the
tracking manually:
Note: The Manual sync, Manual tracking, Horizontal position and Vertical

options are available only for computer sources. The projector
sets these options automatically for video sources.
1.
Turn Auto Image off.
2.
Highlight Manual tracking, and then press the left or right navigation
button repeatedly until the fuzzy vertical bars are gone.
