PC ADJUSTMENT
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 the Multi-Scan system of this projector.  If this happens, the 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 PC ADJUSTMENT function, to enable you to precisely adjust several parameters to match
with those special signal formats.  This projector has five independent memory areas to memorize those
parameters manually adjusted.  This enables you to recall the setting for a specific computer whenever you use
it. 
Note  : This PC ADJUSTMENT function cannot be operated when “RGB,” “HDTV1035i” or “HDTV1080i” is selected on the
SYSTEM MENU (P22 and 23).
