COMPUTER MODE
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).
Press the MENU button and the ON-SCREEN MENU will
appear.  Press the POINT RIGHT/LEFT buttons to select PC
ADJUST  and press the SELECT button.  Another dialog box
“Where to reserve” MENU will appear. 
In this dialog box, you can store the parameter into the area from
“Mode 1” to “Mode 5.”  When memorizing the new computer
parameter, select the Mode with the message “Free” by pressing
the POINT UP/DOWN buttons and the SELECT button.  To
change the parameters of the Mode previously set, select the
