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 , sharpness and keystone correction
settings.
