Precautions - Pioneer PDP-V402 Technical Manual

Integrator mode
13) Mask for screen top/bottom for NTSC input
This function is valid only when NTSC signals are input. With the remote control, use the 5 and ∞ buttons to select the
item to be set, and confirm your selection with the SET button. With the operation panel, select the item with the + and
– buttons, then confirm your selection with the SET button.
This function selects black or gray mask (MASK GRAY/BLACK) processing for approximately 10 lines at the top or
bottom of the screen, or reproduction of images (MASK OFF) for the whole screen (480 lines).
The factory-preset value is BLACK.

Precautions

• If masked display is used for extended periods, the unmasked and masked areas of the display may begin to exhibit
slightly different display characteristics, as a result of varying rates of phosphor deterioration.
For example, on a masked display receiving NTSC signals that rarely displays a full-screen 480 lines, the top and
bottom masked sections will experience no phosphor deterioration, resulting in possible differences in luminance
and white-balance from the image area.
• Depending on the input source, the display may exhibit some anomalies when the mask is removed, such as a
wavering display at the top on the screen.
14) MP (Motion Picture) mode-setting mode
This function is valid only for PC-9800, VGA, and MAC input signals (and for NTSC inputs double-rate-converted from
RGB-1 and RGB-2 terminals). With the remote control, use the 5 and ∞ buttons to select the item to be set, and
confirm your selection with the SET button. With the operation panel, select the item with the + and – buttons, then
confirm your selection with the SET button. This function allows the selection appropriate for image-sequence processing
or for stills or animations. Select ON for stills and OFF for animations.
• MP mode
When animations such as those used in games are reproduced in the input of non-interlaced signals, including non-
interlaced computer signals, the "stripe-like shadow" may appear in parts of the resulting image. Known as pseudo-
contour, this phenomenon results from the method of gradation expression used to express. Changing the MP mode
to ON can greatly reduce pseudo-contour, though gradation expression may be less sharp, depending on the particular
input signal.
