MANUAL PC ADJUSTMENT

This projector can automatically tune to display signals from most personal computers currently distributed. However, some computers employ special signal formats which may not be tuned by the Multi-Scan system of this projector. If this happens, the projector cannot reproduce proper image and it may be recognized as a flickering; non-synchronized; non-centered; or skewed picture.

Manual PC Adjustment of this projector enables you to precisely adjust several parameters to match with those special signal formats. This projector has 10 independent memory areas to store those parameters manually adjusted, which allows you to recall setting for a specific computer whenever you use it.

Note: The PC ADJUST Menu cannot be operated when the digital signal input on the DVI terminal is selected on PC SYSTEM Menu. (p.25)
