how to use the projectors control panel to adjust the sync.
For adjustment using the configuration menus: 
See Video - Sync.   p.73

TIP
 If you adjust the sync without adjusting the tracking first, it will not 
be possible to get the best adjustment results. Incorrect tracking 
adjustment may not be noticeable with some types of image. 
However, images with lots of lines and shading will tend to show 
incorrect tracking adjustments more clearly, so be sure to check the 
tracking adjustment first.
 It may also be possible to fix flickering and fuzziness by adjusting 
the brightness, contrast
g, sharpness and keystone correction 
settings.
