PC ADJUSTMENT
This projector can automatically detect display signals from most personal computers currently distributed. However,
some computers employ a special signal format which is different from the standard one and the projector cannot detect
it. If this happens, the projector cannot reproduce a proper image. And a flickering picture, a non-synchronized picture, a
non-centered picture or a skewed picture may be projected instead.
For those non-standard formats, this projector is provided with PC ADJUST, enabling you to precisely adjust several
parameters to match with the input signal format. The projector has eight independent memory areas where you can
store the parameter you have set. This enables you to recall the setting for a specific computer when you need it.
NOTE: This PC ADJUSTMENT function cannot be operated  when RGB, HDTV1035i or HDTV1080i is selected on
the COMPUTER SYSTEM SELECT menu. (See pages 36 ~ 37).

4. Press the POINT DOWN BUTTON and a red arrow will appear.
5. Move the arrow to one of the Modes (Free position) where you want to store the parameters by pressing the POINT
UP/DOWN BUTTON(s). Press the SELECT BUTTON to select it.
