TIP
•If you adjust the sync without adjusting the tracking
g first, it will not
be possible to get the best adjustment results. Incorrect tracking
adjustment may not be noticeable with some types of picture.
However, pictures with lots of lines and shading will tend to show
incorrect tracking adjustments more clearly, so be sure to check the
tracking adjustment first.
•Flickering and fuzziness may also occur when the brightness,
contrast
g, sharpness and keystone correction settings are adjusted.
