NORMAL
ADJUSTMENT
SEQUENCE
Most adjustment functions, when selected, display a
slidebar overlayed on the source image. The slidebar
displays the current setting and indicates which arrow keys
to use for making the adjustment. Adjustment settings are
stored in the current setup memory (Input or Recall). There
are two exceptions: 1) If the current setup memory is
locked, new adjustment settings are shown but not stored;
they are discarded when another setup memory is selected.
2) If ASR is on for the current input and an ASI is
performed, the settings are only temporary and are not
saved in the current setup memory.
For new images, where much adjustment is required, it is
recommended that adjustments be made using the sequence
illustrated above. When making picture or geometry
adjustments, follow the sequence displayed in the
adjustment menu.
Tip: When making many picture or geomet~ adjustments,
press - afier each adjustment to return the cursor back
to its previous menu item position.

Primary Display Brightness
Adjustments
The Brightness function is used to adjust the black level of the image.
~ To adjust brightness, press !Z@l then El or lZ1. If video or data is displayed
with a black background, adjust until the background just disappears (black
becomes a very dark grey).
Note: If room lighting changes, it may be necessary to re-adjust brightness.
Contrast
The Contrast function is used to adjust the contrast between the light and dark
areas of the display image.
~ To adjust contrast, press= then E or @. If contrast is set too high, the
image loses detail and clarity. If set too low, it may be difficult to distinguish
between foreground and background information.
Notes: 1) For best results, adjust brightness before contrast. 2) If room
lighting changes, it may be necessary to re-adjust contrast and brightness.
3) An excessively high contrast level can reduce the life of the CRTs.
Detail
The Detail function is used to adjust the picture sharpness of video signals
when using the optional
Marquee
Multi-standard Decoder.
