Resize

allows you 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 4x3 aspect ratio screen.

 preserves the 16x9 aspect ratio of the original 
theater version, but the image is placed in a 4x3 space, so black 
bars appear at the top and bottom of the image. 
Enhanced Wide-
screen
 also preserves the aspect ratio of the original theater ver-
sion and is designed to be used with content that is Enhanced for 
Widescreen TVs. This option yields more detail than Widescreen 
Letterbox.

on again. If the image is still bad, try adjusting the tracking man-
ually:

cally based on the input signal it receives. (The video standard 
options may vary depending on your region of the world.) If the 
projector is unable to detect the correct standard, the colors might 
not look right or the image might appear “torn.” If this happens, 
manually select a video standard.
