This projector can automatically tune to the display signals from most personal computers currently distributed.  However,
some computers employ special signal formats which are different from the standard ones and may not be tuned by Multi-
Scan system of this projector.  If this happens, projector cannot reproduce a proper image and the image may be recognized
as a flickering picture, a non-synchronized picture, a non-centered picture or a skewed picture.
This projector has a Manual PC Adjustment to enable you to precisely adjust several parameters to match with those special
signal formats.  This projector has 5 independent memory areas to memorize those parameters manually adjusted.  This
